[Solved] ComboBox in RadGrid issue

[El]

I want to update a Label control which is inside the same GridItem (row).

I have added the OnSelectedIndexChanged Event to the combobox but i just cannot get the current row as it's (i assume) not selected when you change the combobox index.

I just want to select a new item in the combobox and make it updates the Label1 in the same ItemTemplate (findControl i guess but as mentioned i cannot find the currently selected index.

I tried something along the following but, i am missing something.

01.Protected Sub cmbSetMarkup(ByVal sender As Object, _
02.                ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs)
03.        Dim combo As RadComboBox = DirectCast(sender, RadComboBox)
04.        Dim NewValue As String = combo.SelectedValue
05.
06.        For Each markupItem As GridItem In RadGrid1.MasterTableView.GetItems( _
07.            New GridItemType() {GridItemType.Item, GridItemType.AlternatingItem})
08.            Dim LblPercent As Label = CType(WHATHERE.FindControl("MyPercent"), Label)
09.            LblPercent.SelectedValue = NewValue
10.        Next
11.
12.    End Sub

Hello,

In this event handler you can access the grid dataitem using NamingContainer property of RadComboBox and then access the Label using FindControl() method. Check out the following code below.

ASPX:

<telerik:GridTemplateColumn>
  <ItemTemplate>
    <telerik:RadComboBox ID="RadComboBox1" runat="server" AutoPostBack="true" DataSourceID="SqlDataSource1" DataTextField="FirstName" DataValueField="FirstName" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">
    </telerik:RadComboBox>
  </ItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn>
  <ItemTemplate>
      <asp:Label ID="MyPercent" runat="server" Text='<%#Eval("FirstName") %>'></asp:Label>
  </ItemTemplate>
</telerik:GridTemplateColumn>

VB.Net

Protected Sub RadComboBox1_SelectedIndexChanged(o As Object, e As RadComboBoxSelectedIndexChangedEventArgs)
    Dim combo As RadComboBox = DirectCast(o, RadComboBox)
    Dim NewValue As String = combo.SelectedValue
    Dim item As GridDataItem = DirectCast(combo.NamingContainer, GridDataItem)
    Dim LblPercent As Label = DirectCast(item.FindControl("MyPercent"), Label)
    LblPercent.Text = NewValue
End Sub

Thanks,
Princy.

Thanks princy. I will try that and get back to you. By the way i solved it in a bit different way:

1.Dim combo As RadComboBox = DirectCast(sender, RadComboBox)
2.Dim NewValue As String = combo.SelectedValue
3.Dim row As GridItem = DirectCast(DirectCast(sender, Control).Parent.Parent, GridItem)
4.CType(row.FindControl("LblPercentage"), Label).Text = NewValue

Do you think it's right? Maybe your way is more efficient? Thanks again
