Examples

Customizing auto-generated columns

C#

protected void RadGrid1_ColumnCreated(object sender, GridColumnCreatedEventArgs e)
{
    if (e.Column.UniqueName == "FirstName")
    {
        e.Column.HeaderText = "Name";
        e.Column.AutoPostBackOnFilter = true;
    }
}

VB

Protected Sub RadGrid1_ColumnCreated(ByVal sender As Object, ByVal e As GridColumnCreatedEventArgs)
    If e.Column.UniqueName = "FirstName" Then
        e.Column.HeaderText = "Name"
        e.Column.AutoPostBackOnFilter = True
    End If
End Sub

Localizing the Grid Headers

<telerik:RadGrid RenderMode="Lightweight" ID="RadGrid1" DataSourceID="SqlDataSource1" AllowSorting="True" runat="server" OnColumnCreated="RadGrid1_ColumnCreated">
  <MasterTableView Width="100%" AutoGenerateColumns="True" />
</telerik:RadGrid>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>" SelectCommand="SELECT * FROM [Customers]"> </asp:SqlDataSource>

C#

protected void RadGrid1_ColumnCreated(object sender, GridColumnCreatedEventArgs e)
{
    GridColumn boundColumn = e.Column as GridColumn;
    switch (boundColumn.UniqueName)
    {
        case "ContactName":
            boundColumn.HeaderText = "My customized contact name";
            break;
        case "ContactTitle":
            boundColumn.HeaderText = "My customized contact title";
            break;
        case "Address":
            boundColumn.HeaderText = "My customized address";
            break;
    }
}

VB

Protected Sub RadGrid1_ColumnCreated(ByVal sender As Object, ByVal e As GridColumnCreatedEventArgs) Handles RadGrid1.ColumnCreated
    Dim boundColumn As GridColumn = CType(e.Column, GridColumn)

    Select Case boundColumn.UniqueName
        Case "ContactName"
            boundColumn.HeaderText = "My customized contact name"
        Case "ContactTitle"
            boundColumn.HeaderText = "My customized contact title"
        Case "Address"
            boundColumn.HeaderText = "My customized address"
    End Select
End Sub
