Issue assigning a MultiLine ConfirmText on a BgridButtonColumn

[Tim]

So, I am unable to assign a MultiLine Message as my Confirmation Text for a Delete ImageButton.

The below code, when not REM'd out, does not throw an error but when I hit Delete, the confirmation does not appear at all and it merely Deletes the record.  If I use a single Line of text, it appears and prompts for confirmation.

Not a deal breaker for me but I thought I would mention it.

Private Sub RecipientsGrid_ItemCreated(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles RecipientsGrid.ItemCreated

If TypeOf e.Item Is GridDataItem Then

Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)

Dim DeleteBtn As GridButtonColumn = TryCast(RecipientsGrid.MasterTableView.GetColumn("DeleteOrganization"), GridButtonColumn)

Dim DeleteMsg As New StringBuilder

'DeleteMsg.Append("Delete this Organization?")
'DeleteMsg.Append(ControlChars.NewLine)
'DeleteMsg.Append("Note: This will DELETE all Contacts for this Organization!")
'DeleteBtn.ConfirmText = DeleteMsg.toString

DeleteBtn.ConfirmText = "DELETE ME!"


End If



End Sub

Hi Tim,

Please try the following code snippet.

C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem item = (GridDataItem)e.Item;
        GridButtonColumn DeleteBtn = RadGrid1.MasterTableView.GetColumn("DeleteOrganization") as GridButtonColumn;
        StringBuilder DeleteMsg = new StringBuilder();
        DeleteMsg.Append("Delete this Organization?\\n");
        DeleteMsg.Append("Note: This will DELETE all Contacts for this Organization!");
        DeleteBtn.ConfirmText = DeleteMsg.ToString();

    }
}

Thanks,
Shinu.

Thx, I tried the code and while it does now prompt me, all the text is still on one line and it look slike the below

'Delete this Organization?\nNote: This will DELETE all Contacts for this Organization!'

Just add @ before your strings  (@"text goes here\n")

[Tim]

When I do that, VS gets upset as says Expression Expected.

I tried the Telerik Translator and it can't translate the below.

DeleteMsg.Append(@"Delete this Organization?\\n")
DeleteMsg.Append(@"Note: This will DELETE all Contacts for this Organization!")
DeleteBtn.ConfirmText = DeleteMsg.ToString

Oh, that's right, you use Telerik control :) From your code I see that it could be done using plain Javascript confirm window. I just did it with DataTable, looped through all rows, added one column and it worked perfectly

DataSet ds = data from somehwere;
                StringBuilder campaignsToBreak = new StringBuilder();
                foreach (DataRow row in ds.Tables[1].Rows)
                {
                    campaignsToBreak.Append(row["CampaignName"] + @"\n");
                }

                l.Enabled = true;
                l.Attributes.Add("onclick", @"javascript:return confirm('All related Campaigns will have their link broken.\n\n" +
                    campaignsToBreak + @"\nContinue?')");

Ok, so I did a fair mount of testing, here's what's happening.  If I put any kind of text in the ConfirmText para in the Markup, that text is what's displayed, no matter that I overwrite it from the code-behind. 

Scenario 1. The below example will ALWAYS display XxX.

<telerik:GridButtonColumn ConfirmText="XxX" ConfirmTitle="Delete" UniqueName="DeleteOrganization"  ButtonType="ImageButton" CommandName="Delete" ConfirmDialogHeight="100px" ConfirmDialogWidth="220px"  HeaderStyle-Width="25"  />

If TypeOf e.Item Is GridDataItem Then

          Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)
          Dim DeleteBtn As GridButtonColumn = TryCast(RecipientsGrid.MasterTableView.GetColumn("DeleteOrganization"), GridButtonColumn)
          Dim DeleteMsg As New StringBuilder

          Select Case PageName
              Case "Agreements.aspx"
                  DeleteMsg.Append("Remove from this Agreement!")
              Case "ManageRecipients.aspx"
                  DeleteMsg.Append("Delete Organziation, including all Contacts!!")
          End Select

          DeleteBtn.ConfirmText = DeleteMsg.ToString
      End If

Scenario 2.  This will always just delete the item in question, Without prompting the user.  Can anyone replicate this issue?

<telerik:GridButtonColumn ConfirmTitle="Delete" UniqueName="DeleteOrganization" ButtonType="ImageButton" CommandName="Delete" ConfirmDialogHeight="100px" ConfirmDialogWidth="220px"  HeaderStyle-Width="25"  />

If TypeOf e.Item Is GridDataItem Then

    Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)
    Dim DeleteBtn As GridButtonColumn = TryCast(RecipientsGrid.MasterTableView.GetColumn("DeleteOrganization"), GridButtonColumn)
    Dim DeleteMsg As New StringBuilder

    Select Case PageName
        Case "Agreements.aspx"
            DeleteMsg.Append("Remove from this Agreement!")
        Case "ManageRecipients.aspx"
            DeleteMsg.Append("Delete Organziation, including all Contacts!!")
    End Select

    DeleteBtn.ConfirmText = DeleteMsg.ToString
End If

Greg, thanks for the suggestion, I haven't tried using Javascript instead.
