How do I bind data from a SP to my gridview which all have textboxes for each cell. My asp for is below.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
<Columns>
<asp:TemplateField HeaderText="Year">
<ItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Year") %>'></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Period">
<ItemTemplate>
<asp:TextBox ID="TextBox2" runat="server" Text='<%# Bind("Period") %>'></asp:TextBox>
</ItemTemplate>
Use a SQL datasource: Heres an example of mine. I have my connections in it so you would need to substitue yours.
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ProjectCISConnectionString %>" ProviderName="<%$ConnectionStrings:ProjectCISConnectionString.ProviderName %>"
<SelectParameters>
<asp:ControlParameter name="Textbox1"
ControlID="txttextbox1" Propertyname="Text"/>
</SelectParameters>
</asp:SqlDataSource>

I have two dropdown lists in a detailsview one called College and the other is Department. If the user select a college, the department dropdown list should generate all the departments for the selected college.
Here is the detailsview and the dropdown lists:
<asp:DetailsView ID="DetailsView1" runat="server" Height="50px" Width="600px" AutoGenerateRows="False" CssClass="table table-bordered mtop" DataKeyNames="ID" DataSourceID="SqlDataSource1" OnDataBound="DetailsView1_DataBound">
<FieldHeaderStyle CssClass="DetailsViewHeader" Width="200px" />
<Fields>
<asp:TemplateField HeaderText="College" SortExpression="Colleges">
<EditItemTemplate>
<asp:DropDownList ID="DropDownList2" runat="server" DataSourceID="SqlDataSource3" DataTextField="ArName" DataValueField="Code"></asp:DropDownList>
<asp:HiddenField ID="HiddenColl" runat="server" value='<%# Eval("Colleges") %>' />
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label15" runat="server" Text='<%# Bind("Colleges") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Department" SortExpression="ArName">
<EditItemTemplate>
<asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="SqlDataSource2" DataTextField="ArName" DataValueField="Code"></asp:DropDownList>
<asp:HiddenField ID="HiddenDep" runat="server" value='<%# Eval("ArName") %>' />
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label11" runat="server" Text='<%# Bind("ArName") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField ShowHeader="False">
<EditItemTemplate>
<asp:Button ID="Button1" runat="server" CausesValidation="True" CommandName="Update" Text="Update" />
<asp:Button ID="Button2" runat="server" CausesValidation="False" CommandName="Cancel" Text="Cancel" />
</EditItemTemplate>
<ItemTemplate>
<asp:Button ID="Button1" runat="server" CausesValidation="False" CommandName="Edit" Text="Edit" />
<asp:Button ID="btnDelete" runat="server" CausesValidation="False" Text="Delete" OnClientClick="return confirm('Do you want to delete ?');" OnClick="btnDelete_Click" />
</ItemTemplate>
<ControlStyle CssClass="btn-login" />
<ItemStyle CssClass="text-center" />
</asp:TemplateField>
</Fields>
</asp:DetailsView>
Here is the SqlDataSources:
<asp:SqlDataSource ID="SqlDataSource3" runat="server" ConnectionString="<%$ ConnectionStrings:UEDConnectionStringMarwaMarwa %>" SelectCommand="SELECT [ArName], [Code] FROM [College]"></asp:SqlDataSource>
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:UEDConnectionStringMarwaMarwa %>" SelectCommand="SELECT [Code], [ArName] FROM [Department] WHERE ([CollegeCode] = #CollegeCode)">
<SelectParameters>
<asp:ControlParameter ControlID="DetailsView1$DropDownList2" Name="CollegeCode" PropertyName="SelectedValue" Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
This is the error message:
Could not find control 'DetailsView1$DropDownList2' in
ControlParameter 'CollegeCode'
I did this DetailsView1$DropDownList2 so it can access the dropdown list that is inside the detailsview
What is the problem ?
I am unfamiliar with the DetailsView and not experienced with the SqlDataSource, but I will try to help.
In my experience, I have learned that you shouldn't try to assume a control's ClientID. So, first I would recommend getting the ClientID from the server control.
Using an inline expression, I would try something like this:
<asp:ControlParameter ControlID='<%= DetailsView1.Rows(0).FindControl("DropDownList2").ClientID %>' Name="CollegeCode" PropertyName="SelectedValue" Type="Int32" />
For more about asp.net inline expressions see Introduction to ASP.NET inline expressions in the .NET Framework.
Because I am unfamiliar with the DetailsView control, I don't know if there will be a row at index 0 in the DetailsView when it executes this inline expression (which would throw an exception).
If that code doesn't work, I would suggest dynamically setting the ControlID on the back end that executes after the DetailsView1 rows are bound (such as inside the DetailsView1's DataBound event method).
VB:
If DetailsView1.Rows.Count > 0 Then
Dim objDropDownList2 as Control = DetailsView1.Rows(0).FindControl("DropDownList2")
If objDropDownList2 IsNot Nothing Then
SqlDataSource1.SelectParameters("CollegeCode").ControlID = objDropDownList2.ClientID
End If
End If
C#:
if (DetailsView1.Rows.Count > 0) {
Control objDropDownList2 = DetailsView1.Rows(0).FindControl("DropDownList2");
if (objDropDownList2 != null) {
SqlDataSource1.SelectParameters("CollegeCode").ControlID = objDropDownList2.ClientID;
}
}
I hope this helps!
I present to you my issues (And i apologize for my english ...):
I have a GridView containing the data of my database, from two SqlDataSource, one for my simple items and the second for a dropdown list.
They are:
<asp:SqlDataSource ID="source_personnes" runat="server"
ConnectionString="<%$ ConnectionStrings:Formation_2014ConnectionString %>"
SelectCommand="SELECT Personnes.id_personne, Personnes.nom_personne, Personnes.prenom_personne, Personnes.actif_personne, Personnes.agence_personne, Organismes.raison_sociale FROM Personnes INNER JOIN Organismes ON Personnes.agence_personne = Organismes.id_organisme WHERE (Personnes.actif_personne = 1)"
UpdateCommand="UPDATE Personnes SET nom_personne=#nom_personne, prenom_personne=#prenom_personne, agence_personne = #id_organisme WHERE (id_personne = #id_personne) "
DeleteCommand="UPDATE Personnes SET actif_personne = 0 WHERE (id_personne = #id_personne)">
<SelectParameters>
<asp:Parameter DefaultValue="1" Name="actif_personne" Type="Int16" />
</SelectParameters>
<UpdateParameters>
<asp:ControlParameter Name ="id_organisme" ControlId="id_organisme" />
</UpdateParameters>
</asp:SqlDataSource>
The second one :
<asp:SqlDataSource ID="source_organisme" runat="server"
ConnectionString="<%$ ConnectionStrings:Formation_2014ConnectionString %>"
SelectCommand="SELECT * FROM [Organismes]">
</asp:SqlDataSource>
To explain things, I have the following two tables in my database :
Personnes ( id_personne(PK), nom_personne, prenom_personne, actif_personne, #agence_personne)
Organismes ( id_organisme(PK), raison_sociale, actif_organisme)
agence_personne related to id_organisme.
My goal is by the integrated update function of the GridView, change my entry in the database for the table Personnes.
Thanks to Tuto found on MSDN, here or here, I managed to built my dropdown list, however once you get to step 19 to 20 not for me to make a data bindings as explained. So I have a completely independent list.
I now give you the code for my GridView:
<asp:GridView ID="GridModif" runat="server" AllowPaging="True" AutoGenerateColumns="False"
DataKeyNames="id_personne" DataSourceID="source_personnes" SkinID="dataGrid">
<Columns>
<asp:TemplateField HeaderText="id" SortExpression="id_personne">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("id_personne") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("id_personne") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="nom_personne" HeaderText="Nom" SortExpression="nom_personne" />
<asp:BoundField DataField="prenom_personne" HeaderText="Prénom" SortExpression="prenom_personne" />
<asp:TemplateField HeaderText="Agence" SortExpression="raison_sociale">
<EditItemTemplate>
<asp:DropDownList ID="id_organisme" runat="server"
DataSourceID="source_organisme" DataTextField="raison_sociale"
DataValueField="id_organisme" AutoPostBack="True">
</asp:DropDownList>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="id_organisme" runat="server" Text='<%# Bind("raison_sociale") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:CommandField ShowEditButton="true" />
<asp:CommandField ShowDeleteButton="true" DeleteText="Désactiver" />
</Columns>
</asp:GridView>
My ultimate goal: When I click on my "Edit" button, the selected item in my list is the ID from the table Personne, I would select an element from the "Organismes" table and use it in my update parameters to update the "Personnes" table .
I posted that on other french forum, but i have no answer, I hope you could help me more !
-- Edit --
I've forgot to post my error ><
-> System.InvalidOperationException: Can not find control 'id_organisme' in ControlParameter 'id_organisme
Thanks a lot,
Krishnak
I finally found !
So on my DropDown List, I'd Bind a selected value :
<asp:TemplateField HeaderText="Agence" SortExpression="raison_sociale">
<EditItemTemplate>
<asp:DropDownList ID="agence_personne" runat="server"
DataSourceID="source_organisme" DataTextField="raison_sociale"
DataValueField="id_organisme" AutoPostBack="True"
SelectedValue='<%# Bind("agence_personne") %>' >
</asp:DropDownList>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="agence_personne" runat="server" Text='<%# Bind("raison_sociale") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
And I just remove the Update Parameters in my SqlDataSource. After that, my update works perfectly !
I am getting this exception at runtime which says it cannot find a column 'M' in datasource, but i am not using 'M' anywhere. I am trying to bind data to dropdownlist inside gridview.
I need to do this in .aspx page rather than code behind.
Here's the code i am using:
<asp:GridView ID="grdDrpDownlistSample" runat="server" AutoGenerateColumns="false" DataSourceID="sqlDS1">
<Columns>
<asp:TemplateField HeaderText="User Name">
<ItemTemplate>
<asp:Label ID="lblName" runat="server" Text='<%# Eval("Name").ToString()%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Logged In Status">
<ItemTemplate>
<asp:CheckBox ID="chkStatus" runat="server" Checked='<%# Eval("LoggedIn") %>'></asp:CheckBox>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Sex">
<ItemTemplate>
<asp:DropDownList ID="drpSex" DataSourceID="sqlDS1" runat="server" DataTextField='<%# Eval("Sex") %>' DataValueField='<%# Eval("id") %>' ></asp:DropDownList>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="sqlDS1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="select * from Users"> </asp:SqlDataSource>
It's working now.
I have got this working by removing Eval from dropdownlist, as it was expecting just the column name not the Eval expression.
I have two dropdown within a DetailsView and I want to work in cascade, the idea is that an area contains various issues and these issues depend on the selected area, but I get the following error:
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
in the next line:
<asp:DropDownList ID="ddlIssue" runat="server"
DataTextField="NameIssue" DataValueField="IdIssue"
The complete code is:
<asp:TemplateField HeaderText="Area" SortExpression="IdArea">
<EditItemTemplate>
<asp:DropDownList ID="ddlArea" runat="server"
DataSourceID="SqlDataSource145711" DataTextField="NameArea"
DataValueField="IdArea" AutoPostBack="true"
AppendDataBoundItems="true" SelectedValue='<%# Bind("IdArea") %>'>
</asp:DropDownList>
<asp:SqlDataSource ID="SqlDataSource145711" runat="server"
ConnectionString="<%$ ConnectionStrings:BaseDatosCJConnectionString %>"
SelectCommand="SELECT IdArea, NameArea FROM AREA">
</asp:SqlDataSource>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label5" runat="server"
Text='<%# Bind("IdArea") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Issue">
<EditItemTemplate>
**<asp:DropDownList ID="ddlIssue" runat="server"
DataTextField="NameIssue" DataValueField="IdIssue"**
DataSourceID="SqlDataSource22" SelectedValue='<%# Bind("IdIssue") %>'
</asp:DropDownList>
<asp:SqlDataSource runat="server"
ID="sqlDataSource22"
ConnectionString="<%$ ConnectionStrings:BaseDatosCJConnectionString %>"
SelectCommand="SELECT IdIssue, NameAIssue, IdArea FROM ISSUE"
FilterExpression="IdArea = '{0}'">
<FilterParameters>
<asp:ControlParameter Name="Param" ControlID="ddlArea"
PropertyName="SelectedValue" />
</FilterParameters>
</asp:SqlDataSource>
</EditItemTemplate>
</asp:TemplateField>
Can you help with the solution to this error?
I have to do something from the code?
blessings
Don't you want the problematic area to look like this:
<asp:DropDownList ID="ddlIssue" runat="server"
DataTextField="NameIssue" DataValueField="IdIssue"
DataSourceID="SqlDataSource22" SelectedValue='<%# Bind("IdIssue") %'>
Note that apostrophe ' goes before the closing paren.
How do I get the old values in a gridview row in the row_updating event?
I'm using a sqldatasource control to populate the grid and want to write the update code in the RowUpdating event.
There are 10 fields displayed in the grid.
I can get the value of the first field using
string old_Category = e.OldValues[0].ToString();.
But it doesn't work for index items greater than 0. This doesn't work
string old_Category = e.OldValues[1].ToString();
it returns an error message
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
even though there are 10 columns in the grid.

Just set Enableviewstate property to false of gridview you can get new value
Reference:
http://www.codeproject.com/Questions/139076/not-getting-new-entered-values-on-grid-view-row-up
Just a long shot really. Have you tried setting the DataKeyNames property?
<asp:gridview id="GridView1"
...
DataKeyNames="ProjectID"
/>
From msdn
Use the OldValues property
(dictionary) to access the original
values of the fields in the row to
update. This dictionary contains all
fields in the row except the key
fields. The key fields are defined in
the DataKeyNames property of a
GridView control.
