RadGrid, TemplateColumn and ImageButton

[Mattia]

Hi all,
I have a Rad grid with a column template like the following:

<telerik:GridTemplateColumn HeaderText="Actions" UniqueName="Actions">
 <ItemTemplate>
 <div class="sfBasicLangs">
  <asp:ImageButton runat="server" CommandName="delete" OnCommand="Delete" />
 </div>
</ItemTemplate>
</telerik:GridTemplateColumn>

the Delete method present in the OnCommand is never fired.... how can  have radGrid fire it.
I've already tried to enable viewstate on the grid

Thanks,
Mattia

Hi,

method 1 :

<asp:ImageButton runat="server" CommandName="Userdelete">

ItemCommand()
{
    if(e.CommandName == "Userdelete")
    {
      // write your logic here
     }
}

method 2 :

<asp:ImageButton runat="server" CommandName="Delete">

Deletecommand()
{
   // wrote your logic here
}

Thanks,

Hi Jayesh,
thanks for the answer but I have already implemented the Delete function... The problem is that the function is never fired.

Thanks,
Mattia

Hello Mattia,
I was unable to recreate the issue at my end. Please make sure that you have attached the event correctly. Here am pasting the full code.
aspx:

<telerik:RadGrid AllowAutomaticUpdates="true" ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1"
   AllowPaging="True" CellSpacing="0" GridLines="None" OnItemCommand="RadGrid1_ItemCommand">
  <MasterTableView DataKeyNames="OrderID" PageSize="10" AllowFilteringByColumn="true" CommandItemDisplay="Top" AutoGenerateColumns="False" EditMode="InPlace">
    <columns>
      <telerik:GridBoundColumn DataField="ShipCountry" FilterControlAltText="Filter ShipCountry column" HeaderText="ShipCountry" SortExpression="ShipCountry" UniqueName="ShipCountry">
      </telerik:GridBoundColumn>
      <telerik:GridTemplateColumn HeaderText="Actions" UniqueName="Actions">
         <ItemTemplate>
           <asp:ImageButton ID="ImageButton1" runat="server" CommandName="delete" OnCommand="Delete" />
         </ItemTemplate>
      </telerik:GridTemplateColumn>
     </Columns>
 </MasterTableView>
 </telerik:RadGrid>

C#:

protected void Delete(object sender, CommandEventArgs e)
   {
   }
protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
   {
   }

Thanks,
Princy.

Hi,
i found the problem. The command is fired only if I do the databinding in the Page_Load.
The problem is that I need to have the value of a dropdown to filter the datasource and, as far as the Page_Load event if fired before the controls event I always get the old value.
If I can only bind the grid in the page load how I can I accomplish this?

Thanks,
Mattia

Hello Mattia,

Please examine this help topic to see how the desired functionality can be implemented.

I hope it helps.

Thanks Mira,
I solved my problem by binding the grid with a objectDataSource instead of manually doing it in dropdown onSelectedIndexChanged event.
But I still don't understand why if I do it manually in the onSelectedIndexChanged event the commands are not fired. 

Thanks,
Mattia

Hello Mattia,

In order the RadGrid to work correct, you should data-bind it properly.
Please examine the Telerik RadGrid data binding basics help topic and the Data-binding help section for additional information.

I hope this helps.

All the best,

Hello,

If I am not wrong than this is the IE version specific issue. Please make sure you used latest telerik version.

If you are not able to resolved this issue than please provide your code snippet.

The error was thrown from dadgrid's in-built js file. So, if we add the external style than also it will not resolved your existing issue.

Let me know if any concern.

Thanks,
