                          </table>
                        </FormTemplate>
                     </EditFormSettings>

                   <CommandItemTemplate>
                        <asp:LinkButton ID="lnkbtn_AddNew" runat="server" CommandName="InitInsert" Text="Add New Name"></asp:LinkButton>
                    </CommandItemTemplate>
                  </MasterTableView>
            </telerik:RadGrid>

My scenario is When one process doing no other opertions are allowed. So when i click "add new name" i disbale the add new button and also the links in name field. In edit command and insert command i need to do this and in update and cancel command i need to enable again.? 

I tried but i dont know why it not working. but i had one combo box outside the gridview and when i disable that combobox and enable that working nicely. The add new button's text is set in the itemcreated event of grid. i tried in the item command after databind the insert mode, but after disbale again the itemcreated event calling from override skin property?

Can anyone please give the solution?

Hello Akhil,

I hope the following code snippet will work for you.

C#:

protected void Rad_grd1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if ( e.Item.OwnerTableView.IsItemInserted && e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            LinkButton editbutton = (LinkButton)item.FindControl("lnkbtn_Edit");
            editbutton.Enabled = false;
        }
        if (e.Item.OwnerTableView.IsItemInserted && e.Item is GridCommandItem)
        {
            GridCommandItem commandItem = (GridCommandItem)e.Item;
            LinkButton editbutton = (LinkButton)commandItem.FindControl("lnkbtn_AddNew");
            editbutton.Enabled = false;
        }
     }

Hello Akhil,

Make the following changes in the above code and check whether it works for you.
C#:

 protected void Rad_grd1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if ((e.Item.OwnerTableView.IsItemInserted || Rad_grd1.EditIndexes.Count > 0) && e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            LinkButton editbutton = (LinkButton)item.FindControl("lnkbtn_Edit");
            editbutton.Enabled = false;
        }
        if ((e.Item.OwnerTableView.IsItemInserted || Rad_grd1.EditIndexes.Count > 0) && e.Item is GridCommandItem)
        {
            GridCommandItem commandItem = (GridCommandItem)e.Item;
            LinkButton editbutton = (LinkButton)commandItem.FindControl("lnkbtn_AddNew");
            editbutton.Enabled = false;
        }
    }

Shinu.
