[Solved] Selecting text values in a grid row

[JohnW]

I have searched and searched and all available solutions are not working for me.

I have a RadGrid that I am databinding at runtime. Each time I select a row, it will fire the SelectedIndexChanged, but I get an index error or the value selected is nothing. I'm at my wits end here and I'm not sure how to proceed.

Here's my aspx page:

                <asp:Panel runat="server" ID="DrugList" Height="370px" Width="550" ScrollBars="Auto">

<telerik:RadGrid ID="rgDrugList" runat="server" AllowMultiRowSelection="True"
                    AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" GridLines="None"
                    Height="350px" OnItemCommand="rgDrugList_ItemCommand"
                    Skin="Vista" Width="545px" OnselectedIndexChanged="rgDrugList_SelectedIndexChanged">
                    <MasterTableView>
                        <PagerStyle Mode="NextPrevAndNumeric" />
                        <Columns>
                            <telerik:GridBoundColumn DataField="Name" HeaderText="Drug Name" SortExpression="Name" UniqueName="Name">
                            </telerik:GridBoundColumn>
                        </Columns>
                    </MasterTableView>
                    <ClientSettings EnablePostBackOnRowClick="true">
                        <Selecting AllowRowSelect="True" />
                    </ClientSettings>
                </telerik:RadGrid>

                </asp:Panel>

And here's my vb code:

    Protected Sub form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles form1.Load
        InitializeData()
    End Sub

    Protected Sub InitializeData()
        Dim o As New localhost.Service1
        Dim ds As New DataSet

        ds = o.GetNumbderDrugData

        If ds Is Nothing Then
            errorPanel.Visible = True
            Exit Sub
        End If

        If ds.Tables(0).Rows.Count = 0 Then
            errorPanel.Visible = True
            Exit Sub
        Else
            errorPanel.Visible = False
            rgDrugList.DataSource = ds
            rgDrugList.DataBind()

        End If
    End Sub


Protected Sub rgDrugList_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles rgDrugList.SelectedIndexChanged
        Dim item As GridDataItem = DirectCast(rgDrugList.SelectedItems(0), GridDataItem)
        ' Get the first selected item
        If True Then
            MsgBox(item("Name").Text)
        End If
    End Sub

I have tried using a button as well to fire the event. This doesn't seem to be the issue, as the event fires, I just can't get the value selected. Any help here would be greatly appreciated.

Daniel, thank you so much... I'm not sure what I was doing wrong, because even when I used the OnSelectedIndexChanged I still would not get a value.

OK, next minor issue, the SelectedIndexChanged event is firing twice, any quick fix for that?

Hello John,

Please remove one of the following:

Handles rgDrugList.SelectedIndexChanged

or:

OnSelectedIndexChanged="rgDrugList_SelectedIndexChanged"
