I have a checkbox on my griview and its able to be clicked before the edit button is clicked, this doesn't make sense to me and its not something I have came across before. In theory the checkbox should be greyed out until a user clicks the edit button.
Nothing can be updated but it just doesn't make any sense as to why this functionality would be available. I have set up Gridviews before using checkboxes and never came across this. Below is my code:
<asp:GridView ID="gvLeagues" runat="server"
AutoGenerateColumns="False"
onpageindexchanging="gvLeagues_PageIndexChanging"
onrowcancelingedit="gvLeagues_RowCancelingEdit"
onrowdatabound="gvLeagues_RowDataBound"
onrowediting="gvLeagues_RowEditing"
onrowupdating="gvLeagues_RowUpdating"
onsorting="gvLeagues_Sorting" EnableModelValidation="True"
CssClass="footable"
EditRowStyle-CssClass="table table-bordered" >
No Data Found.
<asp:TemplateField HeaderText="Name" SortExpression="Name">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Name")%>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate><asp:Label ID="Label1" runat="server" Text='<%# Bind("Name")%>'></asp:Label></ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Created Date" SortExpression="CreatedDate">

<EditItemTemplate>
<asp:TextBox ID="TextBox4" runat="server" Text='<%# Bind("Season")%>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate><asp:Label ID="Label4" runat="server" Text='<%# Bind("Season")%>'></asp:Label></ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Enabled" SortExpression="Enabled">
<EditItemTemplate>
<asp:CheckBox ID="chkEnabled" runat="server" Checked='<%# Eval("Enabled")%>' />
</EditItemTemplate>
<ItemTemplate><asp:CheckBox ID="chkEnabled" runat="server" Checked='<%# Eval("Enabled")%>' /></ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
When using the ItemTemplate, you are the one specifying what and how you want to see it. Just set that checkbox as disabled.
<asp:TemplateField HeaderText="Enabled" SortExpression="Enabled">
<EditItemTemplate>
<asp:CheckBox ID="chkEnabled" runat="server" Checked='<%# Eval("Enabled")%>' />
</EditItemTemplate>
<ItemTemplate><asp:CheckBox ID="chkEnabled" runat="server" Checked='<%# Eval("Enabled")%>' enabled="False"/></ItemTemplate>
</asp:TemplateField>

I have GridView:

It work fine, but when I add RegularrExpressionValidator for textbox with id="tbDate" mygrid does not work
This regular expression must accept datetime in format "dd.MM.yyyy"
<asp:GridView ID="MyGridView" runat="server" ShowFooter="true"
AutoGenerateColumns="False" Visible="True">

<asp:BoundField DataField="id" ItemStyle-HorizontalAlign="center"/>

I think you typed "tbData" instead of "tbDate" in the ControlToValidate property
<asp:RegularExpressionValidator ID="RegularCert" runat="server"
ControlToValidate="tbDate" ErrorMessage="Incorect Data" ValidationExpression= "(0[1-9]|[12][0-9]|3[01])[-.](0[1-9]|1[012])[-.](19|20)[0-9]{2}"
Display="Dynamic"></asp:RegularExpressionValidator>
I changed ClientIDMode to Predictable for TextBox, RegularExpressionValidator and RequiredFieldValidator and began to work
change ControlToValidate="tbData" to ControlToValidate="tbDate" for <asp:RegularExpressionValidator
Have you tried placing the <asp:RegularExpressionValidator ...> inside the
<ItemTemplate>
<asp:TextBox ID="tbDate" runat="server"></asp:TextBox>
</ItemTemplate>
also you need to indicate some text to display if it fails the regex validation
actually what Hallie said is more than likely the answer ha
I am trying to build a simple GridView.
I have a Products table and it contains ProductID and ModelName.
I am using LINQ to SQL
My GridView code is
<asp:GridView ID="GridView1" runat="server" DataSourceID="objData" AutoGenerateColumns="false" AutoGenerateEditButton="true" DataKeyNames="ProductID,ModelName">
<Columns>
<asp:TemplateField HeaderText="Product ID">
<ItemTemplate>
<asp:Label runat="server" Text='<%#Eval("ProductID") %>'/>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Model Name">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%#Eval("ModelName") %>'/>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox runat="server" Text='<%#Eval("ModelName") %>'/>
</EditItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
and my datasource code is
<asp:ObjectDataSource ID="objData" runat="server" SelectMethod="GetAll" UpdateMethod="UpdateProduct"
DataObjectTypeName="TestLINQProto.tblProduct" TypeName="TestLINQProto.ProductsList"></asp:ObjectDataSource>
I have my update method written like this
[DataObjectMethod(DataObjectMethodType.Update,true)]
public void UpdateProduct(tblProduct product)
{
EshopDataAccess.UpdateProduct(product);//This will call a LINQ function to update the product
}
The issue is that the tblProduct that the UpdateProduct contain original values. It is not getting the updated values.
I think the issue is that you are using Eval method which only supports reading/fetching of data. Use Bind Method in your grid aspx code. Like this
<asp:GridView ID="GridView1" runat="server" DataSourceID="objData" AutoGenerateColumns="false" AutoGenerateEditButton="true" DataKeyNames="ProductID,ModelName">
<Columns>
<asp:TemplateField HeaderText="Product ID">
<ItemTemplate>
<asp:Label runat="server" Text='<%#Eval("ProductID") %>'/>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Model Name">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%#Eval("ModelName") %>'/>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox runat="server" Text='<%#Bind("ModelName") %>'/>
</EditItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

You can use a
Validation Group
Define a separate group for each operation
SaveRecords
&
EditRecords
. You have to specify each validation group on the Save/Edit buttons & all corresponding validation controls to fire them for that event.
MSDN
After a long Time
but you must add in footer requiredfieldvalidator a validationgroup with a unique name and add this validationgroup to add button
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

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.
