Selecting a cell value from a row in radgrid

[naheedkassam]

Hi,

I am having an issue where i want to be able to read the value of a particular cell from a selected row in telerik radgrid.

I am using the following code:

<%@ Page Language="C#" MasterPageFile="~/Page.master" AutoEventWireup="true" CodeFile="ProductSignup.aspx.cs" Inherits="ProductSignup" Title="Untitled Page" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
    <style type="text/css">
        .style2
        {
            width: 100%;
        }
    </style>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
    <table class="style2">
        <tr>
            <td>
                <asp:Panel ID="Panel1" runat="server" Height="416px">
                    Select A Product Type:<br />
                    <asp:RadioButton ID="rdPersonal" runat="server" AutoPostBack="True" 
                        GroupName="G2" oncheckedchanged="rdPersonal_CheckedChanged" 
                        Text="Personal Drives" />
                    &nbsp;&nbsp;&nbsp;&nbsp;
                    <asp:RadioButton ID="rdBusiness" runat="server" AutoPostBack="True" 
                        GroupName="G2" oncheckedchanged="rdBusiness_CheckedChanged" 
                        Text="Business Drive" />
                    <br />

                    <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />
                    <br />
                </asp:Panel>
            </td>
            <td>
                <asp:Panel ID="Panel2" runat="server">
                </asp:Panel>
            </td>
        </tr>
    </table>
</asp:Content>

c# code behind is as follows:

protected void Button1_Click(object sender, EventArgs e)
    {
        string s3;
        foreach (GridDataItem selectinganItem in RadGrid1.MasterTableView.Items)
        {
            if (selectinganItem.Selected)
            {
                Label1.Text = selectinganItem["item_price_iy"].Text;
            }
        }
    }

Whenever i select a row and click on the button - the label1.text does not change. In debugging it shows that the radgrid row selected value is always false.

I used similar code elsewhere in my site and it works fine.

Please help.

I am assuming you are using this:

http://demos.telerik.com/aspnet-ajax/grid/examples/client/selecting/defaultcs.aspx

I don't know what is string s3?

Read this:

http://www.telerik.com/help/aspnet-ajax/grid-accessing-cells-and-rows.html

For your button that goes with the link above:

protected void Button1_Click(object sender, EventArgs e)
   {
       foreach (GridDataItem item in RadGrid1.MasterTableView.SelectedItems) 
       {
           string name = item["item_price_iy"].Text;
       }
   }
