[Solved] Grid disable insert row and Edit/Delete Buttons on edit column

[MikeS]

Hello,

There is a way to disable insert row in radgrid from codebehind if it matches some criteria? 
also, i found a way to disable GridEditCommandColumn, but it disables the two buttons, i only want to disable one.

thanks in advance

Hi Mike,

I guess you want to hide the AddNewRecord based on some condition, you can use the PreRender event for this, and to hide a rows edit button you can check condition in the ItemDataBound event as follows:

C#:

protected void RadGrid1_PreRender(object sender, EventArgs e)
{
 if (Some Condition)
 {
  RadGrid1.MasterTableView.CommandItemSettings.ShowAddNewRecordButton = false;
  RadGrid1.Rebind();
 }
else
 {
  RadGrid1.MasterTableView.CommandItemSettings.ShowAddNewRecordButton = true;
  RadGrid1.Rebind();
 }
}
protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
  if(e.Item is GridDataItem)
  {
    GridDataItem dataItem = (GridDataItem)e.Item;
    if (some condition)
    {
     //Access the edit button using its unique name
      LinkButton lnkEdit = (LinkButton)dataItem["GridEditCommandColumn"].Controls[0];
      lnkEdit.Enabled = false;
    }
  }
}

Thanks,

hello princy.

i was able to hide edit button using this code:

Private Sub RadGrid1_ItemCreated(sender As Object, e As GridItemEventArgs) Handles RadGrid1.ItemCreated
If TypeOf e.Item Is GridDataItem Then
Dim btnEdit As ImageButton = TryCast(e.Item.FindControl("EditButton"), ImageButton)

If Not (Condition) Then

    btnEdit .Visible = False

End If
End If
End Sub

however, i cannot do the same thing to delete button. i tried FindControl("DeleteButton") but it doesnt work.

i've already found a way to hide insertrow.

thanks in advance

actually i need to disable InsertItemDisplay, and i still cant do it properly. 

There is a way to disable InsertItemDisplay on code behind?

Hi Mike,

I'm not clear about your requirement on hiding the InsertItemDisplay, if you want to hide the insert form you can set RadGrid1.MasterTableView.IsItemInserted = false. To hide a delete button try the following. If this doesn't help, please elaborate on your requirement.

APSX:

<telerik:GridButtonColumn UniqueName="DeleteButton" Text="Delete">
</telerik:GridButtonColumn>

VB:

Protected Sub RadGrid1_ItemDataBound(sender As Object, e As GridItemEventArgs)
    If TypeOf e.Item Is GridDataItem Then
        Dim dataItem As GridDataItem = DirectCast(e.Item, GridDataItem)
        If condition Then
            Dim lnkDelete As LinkButton = DirectCast(dataItem("DeleteButton").Controls(0), LinkButton)
            lnkDelete.Visible = False
        End If
    End If
End Sub

Thanks,
Princy

Hi Princy,

i was able to disable insert row using RadGrid1.MasterTableView.IsItemInserted = false.
Also, i solved the problem with the delete button in the editRow of the grid so i have all my problems solved.

thanks!
