Hello There, I have a RadGrid, populated using NeedDataSource Event.
Now, I want to get the names of all my groups(ie, values of cells in a column) on a button click as follows
(note: the button is on the same page as grid, not inside the grid)

On Button Click Event :
foreach (GridItem item in rgGroups.Items)
{
GridDataItem ditem = item as GridDataItem;
if (ditem["GroupType"].Text.Trim() == "Customer") //GroupType is a Template Column
{
string grpname = ditem["GroupName"].Text; //GroupName is BoundColumn
customers.Add(gname);
}
}

listGroups.DataSource = customers;
listGroups.DataBind();

But, the string grpname is always null. Not sure, if this the right way.

Thanks,
Sri

Hello,

<Columns>

<telerik:GridBoundColumn DataField="Name" UniqueName="Name" HeaderText="Name">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn>

<ItemTemplate>

<asp:Label ID="Label1" runat="server" Text='<%# Eval("Name") %>'></asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

protected void LinkButton1_Click(object sender, EventArgs e)

{

foreach (GridDataItem item in RadGrid1.MasterTableView.Items)

{

// Bound column

string strName = item["Name"].Text;

// Template Column

string StrNAME = (item.FindControl("Label1") as Label).Text;

}

Thanks,
