Template columns with radiobutton

[Alyssa]

Hi
I have two template columns one with radiobutton the other with a textbox. I want the textbox to be visible only if the radiobutton is selected. How to get this done?

Hi Alyssa,

Please try the following code snippet:

ASPX:

<telerik:GridTemplateColumn HeaderText="Radio" UniqueName="Radio">
    <ItemTemplate>
        <asp:RadioButton ID="RadioButton1" runat="server" AutoPostBack="true" OnCheckedChanged="RadioButton1_CheckedChanged" />
    </ItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn>
    <ItemTemplate>
        <asp:TextBox ID="TextBox1" runat="server" Visible="false"></asp:TextBox>
    </ItemTemplate>
</telerik:GridTemplateColumn>

C#:

protected void RadioButton1_CheckedChanged(object sender, EventArgs e)
{
    RadioButton radio = (RadioButton)sender;
    GridDataItem gdd = (GridDataItem)radio.NamingContainer;
    TextBox txt = (TextBox)gdd.FindControl("TextBox1");
    if (radio.Checked)
    {
        txt.Visible = true;
    }
}

Thanks,
Shinu
