Hi Rahul Barpha,

Access the DropDownList control rendered in EditForm and attach the 'SelectedIndexChanged' event from code behind in ItemCreated event. Then in the SelectedIndexChanged event, you can easily access second DropDownList and set the value. Here is the code example.

ASPX:

    <telerik:GridDropDownColumn UniqueName="DropDownColumn1" ListTextField="CustomerID"
        ListValueField="CustomerID" DataSourceID="SqlDataSource1" HeaderText="Dropdown"
        DropDownControlType="DropDownList">
    </telerik:GridDropDownColumn>
    <telerik:GridDropDownColumn UniqueName="DropDownColumn2" ListTextField="CustomerID"
        ListValueField="CustomerID" DataSourceID="SqlDataSource1" HeaderText="Dropdown"
        DropDownControlType="DropDownList">
    </telerik:GridDropDownColumn>

C#:

    private void list_SelectedIndexChanged(object sender, System.EventArgs e)
    {
        DropDownList dropDown = (DropDownList)sender;
        GridEditFormItem editForm = (GridEditFormItem)dropDown.NamingContainer;
        DropDownList dropDown2 = (DropDownList)editForm["DropDownColumn2"].Controls[0];
        dropDown2.SelectedValue = dropDown.SelectedValue;
    }
    private void list_SelectedIndexChanged(object sender, System.EventArgs e)
    {
        DropDownList dropDown = (DropDownList)sender;
        GridEditFormItem editForm = (GridEditFormItem)dropDown.NamingContainer;
        DropDownList dropDown2 = (DropDownList)editForm["DropDownColumn2"].Controls[0];
        dropDown2.SelectedValue = dropDown.SelectedValue;
    }
