Hi I was wondering if there is any way to bind my server side panel which contains multiple textboxes ,so my textboxes show associated bound fields which coming from data base automatically .
something like this:
in code behind:
myPnl.DataSource=myContext.TableName;
in aspx page:
<asp:Panel runat="server" ID="myPnl">
<asp:TextBox runat="server" Text='<%# Bind("Title") %>' ID="txtTitle" ReadOnly="true">

I have a FormView that is binded to model.
And use such controls inside it:
<asp:TextBox runat="server" ID="txtName" Text='<%#: BindItem.Name %>'></asp:TextBox>
After i've added annotations to the object the form is binded to- validation started to work, but i can't see any validation messages. How to properly do that?
PS:
ValidationSettings.UnobtrusiveValidationMode = UnobtrusiveValidationMode.WebForms;
Have you tried the <asp:ValidationSummary> control?
Like this:
<asp:ValidationSummary ID="ValidationSummary1" runat="server"
DisplayMode="BulletList" ShowModelStateErrors="true" />
I have a table with the following structure,
I need to restructure the table to show the CustomSpaceName in the following order,
Space3 Personal Case Quick case
Space1 Space2
For each entry I will create a link button and pass the CustomSpaceId in query string.
So which is the ASP.NET Data Control matches best with my requirement. I think using the loop and generate table structure is a BAD idea.
No Need of doing that with a old method when ASP.net gives you GridView and other Data Bounding controls
Basically gridview will do the same operation that you told in a efficient way.
You can use the in-built methods.
Grid View
Repeater
ListView
DataList
Here I will recommend DataList.
Use RepeatColumns="4" property.
<asp:DataList ID="DataList1" RepeatColumns="4" runat="server">
<HeaderTemplate>
<asp:Label runat="server" ID="lbl1" Text='Header'></asp:Label>
</HeaderTemplate>
<ItemTemplate>
<asp:Label runat="server" ID="lbl1" Text='<% Eval("CustomSpaceName ") %>'></asp:Label>
</ItemTemplate>
</asp:DataList>
I have datagridview with multiple columns in my asp.net website. And I am displaying a backend sql stored procedure output into this grid using page OnLoad event. First column in the grid contains a checkbox. I have added this checkbox through ItemTemplate, so that all rows will have a checkbox for selecting the row. I want user able to select the checkbox and based on this selection I would like to perform a DB operation.
currently i am using like below, but couldn't able to trigger the event.
<asp:GridView ID="resultGridView" runat="server" >
<Columns>
<asp:TemplateField HeaderText="Processed">
<ItemTemplate>
<asp:CheckBox ID="CheckBoxProcess" runat="server" OnCheckedChanged="resultgrid_CellContentClick"
Checked="false" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
on my code behind, I have method resultgrid_CellContentClick() for checkbox selection change event. But this code, never executed when select checkbox on/off.
You didn't set AutoPostBack="true" in your checkbox, that's why your checkbox event handler did not work. Just set it...
<asp:CheckBox ID="CheckBoxProcess" AutoPostBack="true" runat="server"
OnCheckedChanged="resultgrid_CellContentClick" Checked="false" />
i have used grid view to display data. Now i need to edit the row. I have kept edit link button in template field of grid-view. Now when i click the edit button, i need to retrieve the data for particular row into the server controls, so that user can enter the data into it.
How can i do that?
let me know if any info required..
thanks!

Now, when i click edit from below grid, the data in grid should come up in above form.
There is a different template available in Gridview and you have to use it properly. For example, if you want to edit something, the editTemplate is available for that.. look at the following sample:
<asp:GridView runat="server" ID="grd">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Label runat="server" ID="lbl"></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox runat="server" ID="Textbox1"></asp:TextBox>
<asp:HiddenField runat="server" ID="hdf" />
</EditItemTemplate>
<InsertItemTemplate>
<asp:TextBox runat="server" ID="Textbox1"></asp:TextBox>
<asp:HiddenField runat="server" ID="hdf" />
</InsertItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
have a look on these article
http://www.asp.net/data-access/tutorials/using-templatefields-in-the-gridview-control-cs
http://programming.top54u.com/post/ASP-Net-GridView-Edit-ItemTemplate-Mode.aspx
This is such a general question that you should really review how the GridView works in the first place.
Try reviewing the following example from MSDN regarding GridView editting;
http://msdn.microsoft.com/en-us/library/ms972948.aspx
I have a GridView DataBind with entity ClassA's properties that is working fine.
I am able to directly bind below properties in ASPX file.
ClassA.Id
ClassA.Name
etc.
But ClassA also have a navigation property to related ClassB. I would like in a the same GridView to display related classB's properties.
I try to bind the following in the GridView but it does not work even if I am able to properly evalute the below value in debug mode (entity performs lazy loading when required).
ClassA.classB.Name
How should I proceed ?
You can achive your goal by a template column with an eval function as below;
<asp:TemplateField HeaderText="Name" SortExpression="Name">
<ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server"
Text='<%# Eval("ClassA.ClassB.Name") %>'></asp:TextBox>
</EditItemTemplate>
<asp:Label ID="Label1" runat="server"
Text='<%# Eval("ClassA.ClassB.Name") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
The downside of this approach is disabling the two-way databinding feature by using the late-bound eval method.
