Hi all,
   I'm using outlook type RadGrid for grouping of my records based on certain status. here I'm having couple of doubts.
       1) when I select a row through mouse, and I click the cancel linkbutton the selected row in Grid should be deselected. I tried lot of examples available in forums. but no one is working fine. May be the problem with the type of Grid that I'm using.
       2) I can navigate the records through the arrow keys. It makes me happy... but when i press Enter key on the certain row, I can handle the functionality based on selected row in server side. But here, inline form is opening. I dont want to open the form. Instead, I want to call a server side method.
    
     Hope this problem can be solved easily in Telerik controls.

    Happy coding...:)

    Thanks in advance

Hi Prabhu,

1) Try the following code snippet to cancel the row selection on clicking the cancel button in a row.

ASPX:
<telerik:GridButtonColumn Text="Cancel"  CommandName="Deselect" ButtonType="LinkButton" ></telerik:GridButtonColumn> 
                       

CS:
  protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e) 
    { 
        if (e.CommandName == "Deselect"
        { 
            e.Item.Selected = false
        }  
    } 


2) Here is the code snippet to prevent editing on pressing the 'Enter key'.

ASPX:
<ClientSettings  AllowKeyboardNavigation="true"  > 
    <ClientEvents OnKeyPress="KeyPressed" /> 
  </ClientSettings> 

JS:
 
<script type="text/javascript">  
  
 function KeyPressed(sender, eventArgs)  
{  
  if(eventArgs.get_keyCode() == 13)    
  {  
       alert('Cancel?')  
       eventArgs.set_cancel(true);     
       // to Perform PostBack 
       __doPostBack("RadGrid1");  
        
   }  
}  
</script>  

Thanks
Shinu

Hi Shinu,

          Thanks for you reply... Since I'm not yet implement the Point (2) on my application, It seems to works well.
          For Point 1 - I forget to tell you that I'm placing the "CANCEL" Linkbutton outside the grid. I want that deselection process should be handled in w/ Post back (in JAVASCRIPT).

Thanks in advance,
Prabhu.K

Dear Telerik team,

                Is it possible to collapse/expand the records using Arrow keys in outlook format grid? If yes, please tell me how to do that in client side?

Thanks in advance,
Prabhu.K

Hi Prabhu,

Try the following code snippet to deselect an item on the client side.

ASPX:
   <asp:LinkButton ID="LinkButton1" OnClientClick="Deselect();"  runat="server">Deselect</asp:LinkButton> 

JS:
<script type="text/javascript"
 
function Deselect() 
  var masterTable = $find("<%= RadGrid1.ClientID %>").get_masterTableView(); 
  //Deselect items 
  masterTable.clearSelectedItems(); 
   
</script> 



Thanks
Shinu.
