Change in oneRadgrid should update another Radgrid

[Naresh]

Hi,
 I have 2 radgrids with checkbox for each row and ID column, now If I select some row in grid1 if grid2 has same rowID as grid1 then disable checkbox in grid2 for that ID. Please send me if you have any sample code.
Thanks in advance!!

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,

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.

Never mind its working. Thanks!!

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>

           dynamic data1 = new[] {

          };

           RadGrid2.DataSource = data2;

       }
       protected void Check1_CheckedChanged(object sender, EventArgs e)

               }
           }
       }

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
