[Solved] How to Dynamically get Label text in EditFormSettings in a RadGrid

[Sanjay]

Hello,
I am getting errors on getting a label text value (in EditFormSettings) from the code behind '<%# DataBinder.Eval(Container,"SIDX1H") %>'
in the aspx page. Please see the code below...
I have tried Container.DataItem also but still error.
Any solutions to get the value correctly?
Also Can I get the row header (column) value in the EditFormSettings ?

Here is the Code Behind for Grid Item Command:

 

Protected Sub gv_Search_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles gv_Search.ItemCommand

 

 

'Get the Row index of the click and load the DataKeys (Columns)

 

 

Dim index As Int32 = Convert.ToInt32(e.Item.ItemIndex)

 

 

Select Case e.CommandName

 

 

Case "edit"

 

 

Dim SIDX1H As String = _user.Containers(0).CustomView.SIDX1.ToString ..........

 

Here is the aspx code for Editformsettings:

<

 

EditFormSettings EditFormType="Template">

 

 

<EditColumn ButtonType="LinkButton" CancelText="Cancel" InsertText="Insert Order" UniqueName="col_Edit" UpdateText="Update">

 

 

<ItemStyle BackColor="Black" />

 

 

</EditColumn>

 

 

<FormTemplate>

 

 

<div class="divGVEdit" style="padding-left: 10px;">

 

 

<div style="padding-left: 10px; text-align: left">

 

 

<table id="tblReg" style="border-collapse: collapse;" cellspacing="2" cellpadding="1">

 

 

<tr>

 

 

<td align="left">

 

 

<itemtemplate>

 

 

<asp:Label ID="lbl1" runat="server" Text='<%# DataBinder.Eval(Container,"SIDX1H") %>' />

 

 

</itemtemplate>...........

 

Thanks
Sanjay

Hello Sanjay,

You cannot access the label placed inside a form template in the EditCommand(code behind) of the grid. Instead you can try accessing the label in the ItemDataBound event of the grid:
aspx:

<EditFormSettings EditFormType="Template">
     <FormTemplate>
          <table id="tblReg" style="border-collapse: collapse;" cellspacing="2" cellpadding="1">
              <tr>
                 <td align="left">
                     <asp:Label ID="lbl1" runat="server" Text='<%# DataBinder.Eval(Container.DataItem,"SIDX1H") %>' />
                 </td>
              </tr>
           </table>
      </FormTemplate>
</EditFormSettings>

c#:

protected void RadGrid_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if (e.Item is GridEditableItem && e.Item.IsInEditMode)
        {
            GridEditableItem editItem = (GridEditableItem)e.Item;
            Label lbl = (Label)editItem.FindControl("lbl1");

        }
    }

Thanks
Princy.

HI Princy,

 

Thanks for your reply! The solution to access the label in the ItemDataBound event of the grid is working fine. But there was the same error if I left the label Text='<%# DataBinder.Eval(Container.DataItem,"SIDX1H") %>'. So I replace with Text='' and let the code behind
(as per you c# code) take care of it. I added the line :
lbl.Text = _user.Containers(0).CustomView.SIDX1.ToString() as the last line in the if {} block.

I wanted to know : Can I directly access the row header (columnname )  of the radgrid value in the EditFormSettings  or ItemDataBound? If so how?

Many Thanks,
Sanjay

Hello Sanjay,

You can access the column header in the ItemDataBound event of the grid as shown below:
c#:

protected void gv_Search_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridHeaderItem)
        {
            GridHeaderItem headerItem = (GridHeaderItem)e.Item;
           string strtxt = headerItem["ColumnUniqueName"].Text;
        }
    }

Regards
Princy.
