How to get row index from OnSelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs

[Alec]

I have a radGrid, which contains a list of rows, each row contains a panel and and a radcombox. When user selects a new value in radcombox, i want to update the panel in that row. I am having problem in getting the row index. Apparently, here's my method:

 

protected void rcbContent_OnSelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)

 

{
          int intIndex = //how do i get the current row index?

 

          Panel pnlPreview = rptZones.Items[intIndex].FindControl("pnlPreview") as Panel;

Hi Alec,

Try the following code for getting row index.

ASPX:

 . . .
<telerik:GridTemplateColumn UniqueName="RadCombobBox1">
<ItemTemplate>
    <telerik:RadComboBox ID="RadComboBox1" runat="server" AutoPostBack="true" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">
    <Items>
        <telerik:RadComboBoxItem Text="Item1" />
        <telerik:RadComboBoxItem Text="Item2" />
    </Items>
    </telerik:RadComboBox>
</ItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn UniqueName="Panel1">
<ItemTemplate>
    <asp:Panel ID="Panel1" runat="server">
    </asp:Panel>
</ItemTemplate>
</telerik:GridTemplateColumn>
 . . .

CS:

protected void RadComboBox1_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
{
    RadComboBox combo = (RadComboBox)o;
    GridDataItem item = (GridDataItem)combo.NamingContainer;
    int index = item.ItemIndex;  // Index of row

    Panel pnl = (Panel)item.FindControl("Panel1");  // Corresponding Panel control
    Panel pnlPreview = RadGrid1.Items[item.ItemIndex].FindControl("Panel1") as Panel; // Other way to get corresponding Panel control
}

Thanks...um..it does get the index and update the preview image right for that particular row, but it also clears other rows preview image....Unless i re-bind the datagrid at the beginning of the method...but thats not right....

protected void rcbContent_OnSelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
        {
            RadComboBox combo = (RadComboBox)sender;
            GridDataItem item = (GridDataItem)combo.NamingContainer;
            int index = item.ItemIndex;  // Index of row

            Panel pnlPreview = rptZones.Items[index].FindControl("pnlPreview") as Panel;
            Image imgPreview = new Image();

            int intSelectedContentId = Convert.ToInt16(e.Value);
            if (intSelectedContentId > 0)
            {
                imgPreview.ImageUrl = "//something...new";
                pnlPreview.Controls.Clear();
                pnlPreview.Controls.Add(imgPreview);
            }



        }
