    Creating LinkButton_Click event

    hi all,

    i'm having some linkbuttons in a datagrid. how could i explicitly create an 'on_Click' event for those linkbutton. Because using that link button, i have to open some other applications like MS-Word, Adobe Acrobat reader and all..

    An image button example from a reporting intranet application of mine:

    Code:
    <asp:DataGrid ID="DataGrid1" runat="server" CssClass="d_greyTones" Width="95%" AutoGenerateColumns="False" AllowSorting="True" OnSortCommand="DataGrid1_SortCommand" OnItemCommand="DataGrid1_ItemCommand">
    
    ...
    
    <asp:ImageButton ImageUrl="images/arrow_down.png" ID="btnMoveDown" runat="server" AlternateText="DOWN" CommandName="DOWN" CommandArgument='<%# DataBinder.Eval(Container.DataItem, "REPORT_ID")%>' />
    In the code behind:
    Code:
        protected void DataGrid1_ItemCommand(object sender, DataGridCommandEventArgs e)
        {
    
            if (e.CommandName != "UP" && 
                e.CommandName != "DOWN" &&
                e.CommandName != "SELECT") return;  // other things fire this event, too, such as sorting
            
            long rptId = Int64.Parse(e.CommandArgument.ToString());
            Report report = new Report(rptId);
    
            if (e.CommandName == "SELECT")
            {
                this.ViewReportLink.NavigateUrl = "AdminReportDefinitions_details.aspx?report_id=" + rptId;
    
    ...and so on

    If this post contains any code, I may or may not have tested it. It's probably just example code, so no getting knickers in a bunch over a typo, OK? If it doesn't have basic error checking in it, such as object detection or checking if objects are null before using them, put that in there. I'm giving examples, not typing up your whole app for you. You run code at your own risk.
