[Solved] DropDownList in RadGrid

[GarryP]

Hi, I have added dropdownlist for the each raws in a radgrid. I have managed to add "low,normal and high options  inside the dropdownlist but". I can not get the selected value. in the dropdownlist. I used the code below;

Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.WebControls.GridItemEventArgs) Handles RadGrid1.ItemDataBound


        If TypeOf e.Item Is Telerik.WebControls.GridDataItem Then
            Dim item As Telerik.WebControls.GridDataItem = DirectCast(e.Item, Telerik.WebControls.GridDataItem)
            Dim ddl As DropDownList = DirectCast(item("Temp").FindControl("DropDownList1"), DropDownList)
            
            ddl.Items.Add("Low")
            ddl.Items.Add("Normal")
            ddl.Items.Add("High")
           

            MsgBox(ddl.SelectedValue)
          
           End If


    End Sub

ddl.SelectedValue only gives me the Low option, when i run the page but when i select normal or high or low again. It doesnt seem to be doing anything so i also added the code below.

Protected Sub RadGrid1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadGrid1.SelectedIndexChanged
        MsgBox(ddl.SelectedValue)
    End Sub

But still no use. So is there a way of getting the selected item of the dropdownlist in radgrid?

I have the same problem, but i  use a ObjectDataSource to retrieve data and populate the DDL.
Thanks.

Hi Garry,

The dropdownlist should behave as expected and its selected value be accessible through its SelectedValue property. Could you post your aspx and code behind for the relevant page (please, use the Code Formatter tool of the html editor).

Thank you.

Hi,

I used the code below only to add dropdownlist for each coloumn.


<radg:GridTemplateColumn UniqueName="TemplateColumn">
        <ItemTemplate>
            <asp:DropDownList ID="DropDownList1" AutoPostBack="true" DataTextField="Priority" DataSourceID="SqlDataSource1" DataValueField="Priority" runat="server" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
            </asp:DropDownList>
        </ItemTemplate>
        </radg:GridTemplateColumn>

and I used, the vb.net code below to populate the lists but it only gets the first one, when aspx form loads then when i select other items it doesnt do anything.

Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.WebControls.GridItemEventArgs) Handles RadGrid1.ItemDataBound


        If TypeOf e.Item Is Telerik.WebControls.GridDataItem Then
            Dim item As Telerik.WebControls.GridDataItem = DirectCast(e.Item, Telerik.WebControls.GridDataItem)
            Dim ddl As DropDownList = DirectCast(item("Temp").FindControl("DropDownList1"), DropDownList)
            
            ddl.Items.Add("Low")
            ddl.Items.Add("Normal")
            ddl.Items.Add("High")
           

            MsgBox(ddl.SelectedValue)
          
           End If


    End Sub

Protected Sub RadGrid1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadGrid1.SelectedIndexChanged
        MsgBox(ddl.SelectedValue)
    End Sub

Is there an easier way in vb.net?

Thanks
