ASP.NET

This was fine when I use at .Net 1.1 for the gridview cells, A (in red colour).
But the output for .Net 2.0 was A

public string strAbsent = "A";

Could you please rephrase your question. As it stands all I have is what the output is in .NET 2.0, for which I have no context, and "Why can't I do this in .net 2.0?". Why can't you do what? What worked fine in 1.1? What is wrong with the output from 2.0?

In the past, in .Net 1.1 I have a datagrid and I binded my data using datatable, dataset etc. I have set earlier

public string strAbsent = "A";

In some column the output will show A in red colour in the datagrid.

Now, I am migrating the project to .Net 2.0. I have a gridview and I binded my data using datatable, dataset etc.

But it appears that the output A is no longer in red colour but instead it shows exactly the html tags:

A

thanks in advance. Much appreciated.

Creating a HTML page from ASP.NET

22-Aug-06 8:09

Sorry maybe I did not explain clearly.

The above html tags was from the codebehind. how can I edit the item-template when I would not know where the letter A will appear in the gridview.

------------------------
| |A | | | | | | |
| | | A| | | | | |
| | | | | | | | |
|__|__| A|__|__|__|

Some other letter will appear at the blank cells in the gridview. My purpose is to highlight to user, A with red colour so it catch reader eyes to notice the number of As.

Okay this may be a stupid question, but how do you build an HTML page from within ASP.NET? I'm trying to build an ASPX page where someone can set a bunch of settings for how they'd like a web the page to look like. Then when they hit the submit button, ASP.NET makes the alterations to the page and then loads that newly altered page into the browser. I'd also like to be able to alter the script within the page as well.

Most (if not all) of the examples I've seen to this point are based on the idea of altering the already loaded page, like changing the label1.text = "This has been changed";

Is there a way to make alterations to a different page, and what do they call this? I've Googled a million things such as "building HTML in ASP.NET" and found nothing. This seems like a pretty common task.

Thanks, -=STZ=-

This looks like a typical case in which xsl transformation could work for you.
As I understand you want your webpage to get displayed according to some settings.

You can retrieve these settings in a dataset and create a xml file out of it.
Then you can use the xsl transform to transform this into HTML format.

The way you want to display the html will determine the logic in the xsl file.
I know I haven't included the actual code for you in this but hopes this helps you in some way Wink | ;)

Sorting in Grid View using AJAX

Re: Sorting in Grid View using AJAX

U will also have to give the sortexpression to the bound and template column.
Use Atlas framework for using AJAX. Put the GridView inside an updatepanel and that will do the job
Here is a post showing how to add atlas control to your toolbox

Here is a code snippet of the code that works for sorting. Please change the Connection string and the querys. If you are using Atlas for ajax put the full thing inside the <atlas:updatepanel><contentpanel>. That will do the job.

I want to do sorting in Grid View with help of coding.This is my code
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
getdata()
End Sub

Public Function getdata() As DataSet
Dim adp As New SqlDataAdapter("select CategoryID,CategoryName,Description from categories order by CategoryName ASC", ConfigurationManager.ConnectionStrings("cn").ConnectionString)
Dim dt As New DataTable("categories")
adp.Fill(dt)
Dim dtrowcount As Integer = dt.Rows.Count
If dtrowcount > 0 Then
GridView1.DataSource = dt
GridView1.DataBind()
End If

End Function

Private Property GridViewSortDirection() As String
Get
Return IIf(ViewState("SortDirection") = Nothing, "DESC", ViewState("SortDirection"))
End Get
Set(ByVal value As String)
ViewState("SortDirection") = value
End Set
End Property

Private Property GridViewSortExpression() As String
Get
Return IIf(ViewState("SortExpression") = Nothing, String.Empty, ViewState("SortExpression"))
End Get
Set(ByVal value As String)
ViewState("SortExpression") = value
End Set
End Property

Private Function GetSortDirection() As String
Select Case GridViewSortDirection
Case "ASC"
GridViewSortDirection = "DESC"

Case "DESC"
GridViewSortDirection = "ASC"
End Select
Return GridViewSortDirection
End Function

Protected Function SortDataTable(ByVal datatable As DataTable, ByVal isPageIndexChanging As Boolean) As DataView
If Not datatable Is Nothing Then
Dim dataView As New DataView(datatable)
If GridViewSortExpression <> String.Empty Then
If isPageIndexChanging Then
dataView.Sort = String.Format("{0} {1}", GridViewSortExpression, GridViewSortDirection)
Else
dataView.Sort = String.Format("{0} {1}", GridViewSortExpression, GetSortDirection())
End If
End If
Return dataView
Else
Return New DataView()
End If
End Function

Protected Sub GridView1_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles GridView1.PageIndexChanging
GridView1.DataSource = SortDataTable(GridView1.DataSource, True)
GridView1.PageIndex = e.NewPageIndex
GridView1.DataBind()

End Sub

Protected Sub GridView1_Sorting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewSortEventArgs) Handles GridView1.Sorting
GridViewSortExpression = e.SortExpression
Dim pageIndex As Integer = GridView1.PageIndex
GridView1.DataSource = SortDataTable(GridView1.DataSource, True) GridView1.DataBind()
GridView1.PageIndex = pageIndex
End Sub

I had received an error on Bold line in gridview1_sorting procedure that Unable to cast system.data.dataset to system.data.dataview

Can any body give me solution.
Thanks in advance.
