Hi Naresh,

Please try the sample code snippet. I have used CustomerID column ,to compare from both the grids.Hope this sample helps,let me know if any concern.

ASPX:
<telerik:RadGrid ID="RadGrid1" runat="server">
    <MasterTableView >
        <Columns>
            <telerik:GridTemplateColumn>
                <ItemTemplate>
                    <asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="true" OnCheckedChanged="CheckBox1_CheckedChanged" />
                </ItemTemplate>
            </telerik:GridTemplateColumn>
            <telerik:GridBoundColumn UniqueName="OrderID" DataField="OrderID" HeaderText="OrderID"/>          
            <telerik:GridBoundColumn DataField="CustomerID" HeaderText="CustomerID" UniqueName="CustomerID" />
            <telerik:GridBoundColumn DataField="ShipCity" HeaderText="ShipCity" UniqueName="ShipCity" />
        </Columns>
    </MasterTableView>
</telerik:RadGrid>
<br />
<br />
<telerik:RadGrid ID="RadGrid2" runat="server" >
    <MasterTableView DataKeyNames="CustomerID">
        <Columns>
            <telerik:GridTemplateColumn>
                <ItemTemplate>
                    <asp:CheckBox ID="CheckBox2" runat="server" />
                </ItemTemplate>
            </telerik:GridTemplateColumn>
            <telerik:GridBoundColumn UniqueName="CustomerID" DataField="CustomerID" HeaderText="CustomerID"/>      
            <telerik:GridBoundColumn DataField="ContactName" HeaderText="ContactName" UniqueName="ContactName" />
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

C#:
protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
{
    CheckBox check = (CheckBox)sender;
    GridDataItem item = (GridDataItem)check.NamingContainer;
    string id = item["CustomerID"].Text;
    RadGrid radgrid2 = (RadGrid)form1.FindControl("RadGrid2");
    foreach (GridDataItem ditem in radgrid2.Items)
    {
        string customerid = ditem.GetDataKeyValue("CustomerID").ToString();
        if (string.Compare(customerid, id) == 0)
        {
            CheckBox chk = (CheckBox)ditem.FindControl("CheckBox2");
            chk.Enabled = false;           
        }     
    }
}

Thanks,
Princy

Looks like it is working fine Thanks for the code!! but I have a problem here radgrids are in two different update panels how do I set trigger??
This is the checkbox error that I am getting
Error Message: A control with ID 'Election4CB' could not be found for the trigger in UpdatePanel 'UpdatePanel4'.
Because checkbox is inside telerik so update panel is not detecting event ID.

Hi Princy,
In the below code I have a issue my code is not enabling checkbox for RadGrid2 on Radgrid1 checkbox checked.
UI Code:
<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false" OnNeedDataSource="RadGrid1_NeedDataSource"
        AllowPaging="true">
        <MasterTableView>
            <Columns>
                <telerik:GridTemplateColumn>
                    <ItemTemplate>
                        <asp:CheckBox ID="Check1" runat="server" AutoPostBack="true" OnCheckedChanged="Check1_CheckedChanged" />
                    </ItemTemplate>
                </telerik:GridTemplateColumn>
                <telerik:GridBoundColumn UniqueName="OrderID" DataField="OrderID" HeaderText="OrderID" />
                <telerik:GridBoundColumn DataField="CustomerID" HeaderText="CustomerID" UniqueName="CustomerID" />
                <telerik:GridBoundColumn DataField="ShipCity" HeaderText="ShipCity" UniqueName="ShipCity" />
            </Columns>
        </MasterTableView>
    </telerik:RadGrid>
 
    <br />
 
    <telerik:RadGrid ID="RadGrid2" runat="server" AutoGenerateColumns="false" OnNeedDataSource="RadGrid2_NeedDataSource"
        AllowPaging="true">
        <MasterTableView DataKeyNames="CustomerID">
            <Columns>
                <telerik:GridTemplateColumn>
                    <ItemTemplate>
                        <asp:CheckBox ID="Check2" runat="server" AutoPostBack="true" disabled="disabled" />
                    </ItemTemplate>
                </telerik:GridTemplateColumn>
                <telerik:GridBoundColumn UniqueName="OrderID" DataField="OrderID" HeaderText="OrderID" />
                <telerik:GridBoundColumn DataField="CustomerID" HeaderText="CustomerID" UniqueName="CustomerID" />
                <telerik:GridBoundColumn DataField="ShipCity" HeaderText="ShipCity" UniqueName="ShipCity" />
            </Columns>
        </MasterTableView>
    </telerik:RadGrid>

Code Behind:
protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
       {
 
           dynamic data1 = new[] {
 
              new { OrderID = 1, CustomerID =123,ShipCity = "Tampa"},
              new { OrderID = 2, CustomerID =234,ShipCity = "Tampa"},
              new { OrderID = 3, CustomerID =345,ShipCity = "Tampa"},
              new { OrderID = 4, CustomerID =456,ShipCity = "Tampa"},
              new { OrderID = 5, CustomerID =567,ShipCity = "Tampa"},
 
          };
 
           RadGrid1.DataSource = data1;
 
       }
       protected void RadGrid2_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
       {
 
           dynamic data2 = new[] {
 
              new { OrderID = 1, CustomerID =123,ShipCity = "Tampa"},
              new { OrderID = 2, CustomerID =234,ShipCity = "Tampa"},
              new { OrderID = 3, CustomerID =345,ShipCity = "Tampa"},
              new { OrderID = 4, CustomerID =456,ShipCity = "Tampa"},
              new { OrderID = 5, CustomerID =567,ShipCity = "Tampa"},
 
          };
 
           RadGrid2.DataSource = data2;
 
       }
       protected void Check1_CheckedChanged(object sender, EventArgs e)
       {
           CheckBox check = (CheckBox)sender;
           GridDataItem item = (GridDataItem)check.NamingContainer;
           foreach (GridDataItem itemRG2 in RadGrid2.MasterTableView.Items)
           {
 
               CheckBox chk = (CheckBox)itemRG2.FindControl("Check2");
               if (item["CustomerID"].Text == itemRG2["CustomerID"].Text)
               {
                   if (check.Checked == true)
                   {
                       chk.Enabled = true;
                   }
                   else
                   {
                       chk.Enabled = false;
                   }
               }
           }
       }

Hi Naresh,

I guess you want the checkbox of the second radgrid to be disabled until the CheckBox of first RadGrid is checked. Please set the Enabled property of the CheckBox to false.

ASPX:
<telerik:GridTemplateColumn>
 <ItemTemplate>
<asp:CheckBox ID="Check2" runat="server" AutoPostBack="true" Enabled="false" />
 </ItemTemplate>
</telerik:GridTemplateColumn>

Thanks,
Princy
