Hi Sahil,

One suggestion will be to use a GridTemplateColumn witha CheckBox in its ItemTemplate. You can update the database with the current status of the CheckBox in the CheckChanged event.

ASPX:
 <telerik:GridTemplateColumn UniqueName="TempCol" DataField="Discontinued" HeaderText="Discontinued" > 
                       <ItemTemplate> 
                           <asp:CheckBox ID="CheckBox1" runat="server" Checked='<%#Eval("Discontinued") %>' AutoPostBack="True" OnCheckedChanged="CheckBox1_CheckedChanged" /> 
                       </ItemTemplate>  
                     </telerik:GridTemplateColumn> 

CS:
   protected void CheckBox1_CheckedChanged(object sender, EventArgs e) 
    { 
        CheckBox chkbx = (CheckBox)sender; 
        GridDataItem item = (GridDataItem)chkbx.NamingContainer; 
        bool chkSatus= chkbx.Checked; 
       // perform Update operation 
    } 


Thanks

Hi Sahil,

You can access the CategoryID column value using the Column's UniqueName property in the CheckChanged event of the CheckBox.

CS:
protected void CheckBox1_CheckedChanged(object sender, EventArgs e)  
    {  
        CheckBox chkbx = (CheckBox)sender;  
        GridDataItem item = (GridDataItem)chkbx.NamingContainer;  
        bool chkSatus= chkbx.Checked;  
        // access the cell value using column's UniqueName property 
        string strCategoryid = item["columnUniqueName"].Text; 
       // perform Update operation  
    }  


Thanks
Shinu
