ConfirmText with item data

[miksh]

Is it possible to add the current record data into ConfirmText message? The code below does not work. I know that it can be done in the code behind but I look for simpler solution. 

<telerik:GridButtonColumn UniqueName="DeleteColumn"
    ButtonType="ImageButton"
    CommandName="Delete"
    ConfirmText='Are you sure you want to delete this record with id: <%# Eval("ID")%> ?'
    ConfirmTitle="Delete Record"
    ConfirmDialogType="RadWindow"
    Text="Delete" >
    <ItemStyle HorizontalAlign="Center" Width="20px" />
</telerik:GridButtonColumn>

Hi Miksh,

I'm afraid its not possible from the ASPX side since Telerik.Web.UI.GridButtonColumn does not have a DataBinding event. You can achieve it from code behind as follows:

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
  if (e.Item is GridDataItem)
  {
    ImageButton btn = (e.Item as GridDataItem)["DeleteColumn"].Controls[0] as ImageButton;
    string id= (e.Item as GridDataItem)["ID"].Text;
    btn.OnClientClick = String.Format("if(!confirm('Are you sure you want to delete this record with id: {0}?'))return false;", id);
  }
}

Thanks,
Princy

Thanks Princy,

We tried to use the code below. The weird thing as that the message is always applied to the next row, i.e. if you bind data with IDs: 1,2,3,4 etc, the message will be

ID       Delete Message 
1         ... with ID:
2         ... with ID:1
3         ... with ID:3

Is it a bug? We use Q1 2014 release.

protected void g_ItemDataBound(object sender, GridItemEventArgs e)
{
   if (e.Item is GridDataItem)
   {
       GridDataItem dataItem = e.Item as GridDataItem;
       if (dataItem != null)
          {
               GridColumn deleteColumn = e.Item.OwnerTableView.Columns.FindByUniqueNameSafe("DeleteColumn");
               if (deleteColumn != null)
               {
                    ((GridButtonColumn)deleteColumn).ConfirmText = string.Format("Are you sure you want to delete the record with ID: {0}?", dataItem["ID"].Text);
                }
           }
     }
}

Correction: it should be

ID       Delete Message 
1         ... with ID:
2         ... with ID:1
3         ... with ID:2
etc

Hi Miksh,,

The proper means to invoke a confirm dialog and set its text on a per-row basis (obtaining cell text value from the same row) is by setting onclick attribute for the button inside the GridDataItem as shown in my previous post. Please take a look at this article on Adding a Delete Confirmation.

Thanks,
Princy

If the proper way doing it is onclick then why should I purchase the sophisticated set of well-integrated controls???
Btw, the documentation says that
In this case you need to implement a different approach (without setting the ConfirmText property for the delete column),...

My point is:

1. radGrid delete functionality provides seamless integration with radWindow.
2. It simplifies the process with ConfirmText, ConfirmTitle properties
3. If needed these properties could be easily changed in the code-behind
4. My code snippet shows that it works
5. But there seen to be a bug as the updated messages is applied to the next row.

Hello Michael,

You can use ConfirmTextFields to achieve the requested functionality. I believe we discussed this requirement with your colleague in ticket with ID:803446. In any case, I'm attaching the sample project to this post, too.

Hope this helps.
