You can go to the watch tab and type in expressions to see their values when you're at a breakpoint.

Performance Issues while populating datagrid

26-Jun-08 2:16

Can you not use setfocus to set the focus to a specific record in the grid?

Well, one common sense UI decision would be to not have 10,000 records in your grid.

The datagrid is designed for common UI tasks. If you need to load 10,000 records, you need to find a commercial grid that deals with this ( essentially by only loading small subsets of that data at a time )

This is weird! [modified]

This seems to be a common question in this forum.
Why not cut down the number of records by filtering them, maybe on search criteria by a user.This way not so many are being binded to a datagrid
Other then that follow the advice of CG

I'm creating a multilingual website so I'm trying to dynamically include the language related stylesheet. As you might have already expected, I do this in the page head using a link tag. Well, for some reason I'm not aware of, the code below doesn't work (when I move it outside the the page head, it works though!):

<link rel="stylesheet" href="/css/<%= _language.Stylesheet %>" type="text/css" media="screen" />

It gives this output:

<link rel="stylesheet" href="/css/<% _language.Stylesheet %>" type="text/css" media="screen" />

On the other hand this code works perfectly:

<link rel="stylesheet" href=<%= string.Format("\"/css/{0}\"", _language.Stylesheet) %> type="text/css" media="screen" />

This is really weird, can anybody explain what's going on?!!

P.S. This is ASP.NET 2.0

UPDATE

When tried to remove runat="server" from the head tag, it actually worked! The problem is that I set the page title in my code so I have to keep runat="server" in the head tag, it seems like a bug to me, what do you think?

I haven't had such an issue. you can add stylesheets from code behind page. Try that instead of doing this.

I try to run "http://localhost/localstart.asp" but i can't run it with iis 5.0(my machine os is win xp pro sp2 with iis 5.0).
and i got this error

Server Application Error
The server has encountered an error while loading an application during the processing of your request. Please refer to the event log for more detail information. Please contact the server administrator for assistance.

So, i decide to reinstall iis and vs.net 2008 and install
- iis
- vs.net 2008
respectively,
for hope that it would re-map iis and asp.net. (- -)!
i've also give ASPNET permission to the virtual directory folder and choose ASP.NET version for it.
but i still didn't work and got the Server Application Error again .

any ideas
thank
^^

at the moment i am using this but it is not working.

code to populate 1st ddl from sql server

Table format:
FruitCat nvarchar(50)
FruitName nvarchar(50)

<br />
Private Sub GetFruitsCat()<br />
<br />
        Dim objConnection As SqlConnection = New _<br />
            SqlConnection("Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=MyDB;Data Source=MyServer\SQLEXPRESS")<br />
<br />
        objConnection.Open()<br />
<br />
        Dim myCommand As New System.Data.SqlClient.SqlCommand()<br />
        myCommand.Connection = objConnection<br />
<br />
        myCommand.CommandText = "SelectAllTheFruitsCat"<br />
        myCommand.CommandType = CommandType.StoredProcedure<br />
<br />
        Dim param As New System.Data.SqlClient.SqlParameter()<br />
<br />
        <br />
        Dim myAdapter As New SqlDataAdapter(myCommand)<br />
<br />
        myAdapter.Fill(DataSetOfAllTheFruitsCat)<br />
<br />
        <br />
        Dim reader As SqlDataReader = myCommand.ExecuteReader()<br />
        <br />
<br />
        DDLFruitsCat.DataSource = DataSetOfAllTheFruitsCat<br />
<br />
        DDLFruitsCat.DataTextField = "FruitCat"<br />
<br />
        DDLFruitsCat.DataBind()<br />
        <br />
        objConnection.Close()<br />
<br />
    End Sub<br />

This is the code to get Fruit depending on the fruit category selected in the 1st DDL

<br />
Private Sub GetFruits()<br />
        Dim objConnection As SqlConnection = New _<br />
            SqlConnection("Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=MyDB;Data Source=MyServer\SQLEXPRESS")<br />
<br />
        objConnection.Open()<br />
<br />
        Dim myCommand As New System.Data.SqlClient.SqlCommand()<br />
        myCommand.Connection = objConnection<br />
<br />
        myCommand.CommandText = "SelectASpesificCatFruit"<br />
        myCommand.CommandType = CommandType.StoredProcedure<br />
<br />
        Dim param As New System.Data.SqlClient.SqlParameter()<br />
<br />
<br />
        param = myCommand.Parameters.Add("@FruitCat", _<br />
                                          SqlDbType.NVarChar)<br />
        param.Direction = ParameterDirection.Input<br />
        param.Value = DDLFruitCat.Text<br />
<br />
        Dim myAdapter As New SqlDataAdapter(myCommand)<br />
<br />
        myAdapter.Fill(DataSetOfFruit)<br />
<br />
        Dim reader As SqlDataReader = myCommand.ExecuteReader()<br />
<br />
        DDLFruit.DataSource = DataSetOfFruit<br />
<br />
        DDLFruit.DataTextField = "FruitName"<br />
<br />
        DDLFruit.DataBind()<br />
<br />
        objConnection.Close()<br />
End Sub<br />

i am calling GetFruits here

<br />
Protected Sub DDLFruitsCat_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DDLFruitsCat.SelectedIndexChanged<br />
        GetFruits()<br />
End Sub<br />

2nd ddl is not changing according to data in 1st ddl.

OK, this isnt a fix to your problem but an alterntive solution.
Try the ajax cascading dropdown, very useful for what you want
