Problem adding multiple header rows to a gridview

Posted By:      Posted Date: October 22, 2010    Points: 0   Category :ASP.Net
 

Hello all!

I'm having difficulty adding a repeating header row, every x rows, to a gridview.  I'm able to add the header only once with the below code.  For some reason it will only add it during the last iteration through the for/next statement.  I tried manually adding three separate .addat statements to different rows and it only executed the last .addat statement.  I couldn't find any information on why it's only working the one time and I hope someone has a fix or better solution.

Thanks in advance!

Code snippet (Note the IsWhole() function verifies that the rownumber divided into a whole number):

Protected Sub Gridview1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles Gridview.DataBound

        Dim grid As GridView = TryCast(sender, GridView)

        If grid IsNot Nothing Then

            Dim row As New GridViewRow(0, -1, DataControlRowType.Header, DataControlRowState.Normal)
            Dim header As GridViewRow = POSTURE_RESULT.HeaderRow
            For i As Integer = 0 To POSTURE_RESULT.Columns.C

How to access multiple header rows of the gridview in Render method

  

I have extended a gridview to add an additional header with following two hyperlink controls "Select All" and "Clear All". These will operate on checkboxes in the data rows of the grid. I hide the column headers as I only want to show one column with checkboxes and "Select/Clear All" links. Everything is working as expected. 

Now, I wanted to add a scrollbar to my grid control, I did add the scroll bar using div but what it does is, it includes the "Select All and Clear All" links aswell. I only need to add the scrollbar to datarows and not to the header.

I am trying to extend my control to include hte scrollbar by adding div during Render function. But how will I determine or loop through header rows? How will i get the header row with hyperlinks that I created above?? In Render if I do this.HeaderRow, it gets the original column header and not the custom header. Please help!!!

Gridview Header & table data alignment problem

  

Hi,


Newbie to ASP.net. Programming in C#.

I'm querying a SQL database and displaying the results in a gridview.

The results can be many records so I need to provide the facility to scroll. To display the headers when scroling I have implemented ( in my asp code) the headers in another table and the data is in another table. I see now I cannot align the column headers with the table data.

Appreciate any help to fix this issue.

If this method is not a good one to display headers with data please suggest another method.( Some example code guidance would really help)


Here is my ASP code.

<div id="divProjectTableHeaderFullDetail" runat="server" style="background-color: #993300;
            height: 40px; width: 770px; margin: 0;  padding: 0 ; " >
            <table style="font-family: Arial; font-size: 10pt; color: white;" cellspacing="0"
                cellpadding="0">
                <tr>
