Problem with control in radgrid itemtemplate

[Marta]

Hi,
I am trying to access the selected value of a radiobuttonlist which is placed inside a radgrid. The problem is that the control is directly in radgrid>MasterTableView>ItemTemplate. It is not in a TemplateColumn or anything of the sort. I tried acessing it directly through the name of the radgrid "FichaConteudo" but I get the error "Object reference not set to an instance of an object." so I figure I'm not accessing the control in the correct way. Here is part of my aspx code:

<telerik:RadGrid ID="FichaConteúdo" DataSourceID="GET_DETAILS_CONTEUDO" runat="server"
                GridLines="None" MasterTableView-CommandItemStyle-BorderColor="Transparent" BorderColor="transparent" ShowHeader="False">
                <MasterTableView TableLayout="Fixed" CellSpacing="-1" DataSourceID="GET_DETAILS_CONTEUDO" >
                    <ItemTemplate>
                    <p></p>
                            <asp:RadioButtonList ID="RadioBtnListTipo" runat="server" DataSourceID="GET_TIPOS" DataTextField="Tipo" DataValueField="Tipo" />
...

Here is how I am trying to access the control:

 

RadioButtonList myRadioBtnListTipo = (RadioButtonList) FichaContedo.FindControl("RadioBtnListTipo");

Thank you for your help!
Marta

Hello Marta,

You can try out the following code to access the RadioButtonList in the ItemTemplate of the MasterTableView:
c#:

 protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        foreach (GridDataItem item in FichaConteúdo.Items)
        {
            RadioButtonList myRadioBtnListTipo = (RadioButtonList)item.FindControl("RadioBtnListTipo");

        }
    }

Thanks
Princy.

Thanks! I had to add this line outside the foreach so that I could acess the control in my select statement afterwards as I have this code in a protected void button_submit and not in  protected void RadGrid1_PreRender(object sender, EventArgs e) like you suggested.

 

RadioButtonList myRadioBtnListTipo = new RadioButtonList();

It works, hope it's fine!
