Hi Tony,

You can try the following code snippet in the PreRender event to set a Grid row in edit mode depending on the cell value.

VB:

    Protected Sub RadGrid1_PreRender(ByVal sender As Object, ByVal e As EventArgs)
        For Each item As GridDataItem In RadGrid1.MasterTableView.Items
            If item("ProductID").Text = "3" Then
                item.Edit = True
            End If
        Next
        RadGrid1.MasterTableView.Rebind()
    End Sub

You may also refer the following forum discussion if you are trying to achieve cell editing in Grid.

Hi Shinu

Thanks for the quick reply but what i'm trying to do is something different
I have a grid that consists of 2 checkboxes Checkbox1 Readonly = false and checkbox2 readonly = true , When loading the grid i loop thru all the item and make them editable. But what i want to is when looping thru the grid, I check if the checkbox1 is checked then i change the Checkbox2 readonly = false so i'm able to select.

Please let me know

Thanks

Tony

Hello Tony,

Try the following approach and let me know whether it is suitable for your scenario.

<telerik:GridTemplateColumn ...>
   ...
    <EditItemTemplate>
        <input type="checkbox" id="CheckBox1" runat="server"  checked='<%# Eval("Checked") %>'  />
    </EditItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn ....>
    ....
    <EditItemTemplate>
        <input type="checkbox" id="CheckBox2" runat="server"  />
    </EditItemTemplate>
</telerik:GridTemplateColumn>

Protected Sub RadGrid1_ItemDataBound(sender As Object, e As GridItemEventArgs)
    If e.Item.IsInEditMode Then
        Dim cb2 As HtmlInputCheckBox = TryCast(e.Item.FindControl("CheckBox2"), HtmlInputCheckBox)
        Dim cb1 As HtmlInputCheckBox = TryCast(e.Item.FindControl("CheckBox1"), HtmlInputCheckBox)
        cb2.Disabled = Not cb1.Checked
    End If
End Sub
