Provided of course that the ordinal of the columns doesn't change.

This is a bit brute force and not really necessary.

First way would be to have the database query return only the column you are looking for.

Otherwise try this

DataTable EmployeeName = new DataTable();<br />
EmployeeName.Columns.Add("EmployeeName");<br />
EmployeeName.Merge(fullDataTable);

How to add events to exec time rendered controls?

Hi everybody.

Currently i'm developing a system in Visual Basic .NET under 1.1 Framework, that requires add a couple of webcontrols (mainly Buttons), and i need these controls to respond to events, like the Click one. Is very easy to do this to a control added to a project on design time. But if i want to add buttons on execution time, and that every button responds to a click doing something (something simple like raise a javascript message, or delete a database record) i get confused.

I tried using Button.Attributes.Add("onclick", "something-to-do") but this approach is not working at all.

I really apreciate if someone knows how to do this.

Kind regards,
Leistath. Sniff | :^)

In vb.net use

<br />
'After you create your control<br />
AddHandler Button1.Click, AddressOf Button1_Click<br />
<br />
<br />
 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)  <br />
<br />
'put your code here, it should fire on postback<br />
End Sub

I didn't get any requirements for the signature

hi,

its Asp.net discussion forum. i think you are trying to use the asp.net method in the

vb.net.

you have to add some handlers for this.

eg.

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

AddHandler Me.Click, AddressOf form_click

End Sub

Sub form_click(ByVal sender As Object, ByVal e As System.EventArgs)

End Sub

This handler will be called when the form has been clicked.

Try this type and you can remove it

through

removehandler Me.Click, AddressOf form_click

All The Best

add header after each 15 Records

Hi all,
Some time before I was struggling with Page break. now I found the method for page break nad still finding to add columns headers after 15 rows.
I am using the following script to set up the page break after printing 15 items in a page. It is working all right. Is there any other way to insert page break after certain page margin?

protected void GVMaterialMovement_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
count++;
if(count > 15)
{
e.Row.Style.Add("page-break-after", "always");
count = 0;
}
}
}

Is there any similar way to add header after each 15 Records?

I am not sure what programming language and what version of .net you are looking for. Here is an example in vb.net for .net 1.1

Private Sub ShowMessageBox(ByVal aMessage As String)
        'This procedure will cause a dialog box to pop up with whatever message is passed in.
        aMessage = aMessage.Replace(vbCrLf, "\n").Replace("""", "'")

        Dim myScript As New StringBuilder
        With myScript
            .Append("<script>")
            .Append(Environment.NewLine)
            .Append("alert(""").Append(aMessage).Append(""");")
            .Append(Environment.NewLine)
            .Append("</script>")
            Page.RegisterStartupScript("Promo Error", .ToString())
        End With
    End Sub

It is slightly different for .net 2.0 and the syntax is a little different for C#.

Hope that helps.

Thanks for all ur Replies. I will check your suggestions,

Im using dotnet2005 i.e version2.0 and vb.net as codebehind

Re: Message box

kubben6-Jul-07 4:34

In that case the code is slightly different:

Private Sub ShowMessageBox(ByVal aMessage As String)
        'This procedure will cause a dialog box to pop up with whatever message is passed in.       
        aMessage = aMessage.Replace(vbCrLf, "\n").Replace("""", "'")
        Dim myScript As New StringBuilder
        With myScript
            .Append("<script>")
            .Append(Environment.NewLine)
            .Append("alert(""").Append(aMessage).Append(""");")
            .Append(Environment.NewLine)
            .Append("</script>")
            ClientScript.RegisterStartupScript(Me.GetType(), "Promo Error", .ToString())
        End With

    End Sub

There are some things you can do with javascript, but nothing works all the time. I would guess you aren't interested in javascript you want something to happen on the server side like expire a session or something like that. There really isn't any good way of doing it. If you do a google search on browser closing event you will see some discussions on this and what other people have tried.
