Try paging the data instead of trying to display it all at once. You will get better performance also.

You need to work arround from the example below.
Define your datagrid as below
<asp:DataGrid id="DataGrid1" style="Z-INDEX: 101; LEFT: 8px; POSITION: absolute; TOP: 8px" runat="server"
AutoGenerateColumns="False">
<Columns>
<asp:TemplateColumn>
<ItemTemplate>
<P>
<asp:Label id="lblName" runat="server" Width="144px">Label</asp:Label></P>
<P>
<asp:Label id="lblCountry" runat="server" Width="144px">Label</asp:Label></P>
<P> </P>
</ItemTemplate>
</asp:TemplateColumn>
<asp:BoundColumn Visible="False" DataField="Firstname"></asp:BoundColumn>
<asp:BoundColumn Visible="False" DataField="Lastname"></asp:BoundColumn>
<asp:BoundColumn Visible="False" DataField="Country"></asp:BoundColumn>
</Columns>
</asp:DataGrid>
Finally DataGrid1_ItemDataBound :
Dim lblName As Label
Dim lblCountry As Label
If e.Item.ItemType <> ListItemType.Header And _
e.Item.ItemType <> ListItemType.Footer Then
lblName = CType(e.Item.FindControl("lblName"), Label)
lblName.Text = e.Item.Cells(1).Text & " " & e.Item.Cells(2).Text
lblCountry = CType(e.Item.FindControl("lblCountry"), Label)
lblCountry.Text = e.Item.Cells(3).Text
End If

Ok, I found this article that showed me the right way to solve a problem I had a long time ago. I was using VS 2003 then and the solution involved .inc files ( the article is here http://msdn.microsoft.com/library/en-us/dnpatterns/html/ImpPageController.asp[^] search for basepage.inc to see what I'm talking about )
Are .inc files in VS 2005? (I couldn't find them) and if not what is the equivalent to .inc files or what is the equivalent approach in VS 2005?

Hi there. In the ASP.NET 2.0, you might want to look at the MasterPage[^] concept.

Hello,
I need a little bit of help. I cant seem to figure out how to do this. Here is my current situation:
I have a DataSet that holds all the data needed for the current webpage. It contains a customers information as well as the customers order information. What i need to do now, is seperate the order information into 2 GridViews; Delivery and Pick Up.
The two gridview are based on a Date and a Type (being Del or Pick). All the order items for the given Delivery Date need to go into one GV and the Pickup order items into the other based on its Date.
In addition, there is customer information that needs to be seperated out and put into different Labels throughout the page.
How do i seperate all the data to do what i need?
If you use example, i would appresiate if they are in C#, but anything helps 
Cheers,
Steve

DataSet.Tables[0].Select("Type = Del");
DataSet.Tables[0].Select("Type = Pick");
or
DataSet.Tables[0].DefaultView.RowFilter = "Type = Del";
DataSet.Tables[0].DefaultView.RowFilter = "Type = Pick";

Wow seems easy enough, thank you.
Few questions about your answer, which of the two methods is the prefered way of doing this operation? Does one create less overhead than another or execute faster?
Cheers,
Dev Djinnx

The first method returns an array of DataRows, the second just filters the DataView on the table. For overhead considerations then the first has more. Performance-wise, I haven't measured it, but I don't believe there is any significant difference.

I'm having a problem creating a cookie for a website.
I want to set a cookie on the browser that is destroyed when the user closes the browser.
I'm using the code below and if I dont set the Expires property (which is what I read makes a cookie a 'session cookie'), the cookie is never created.
I tried putting the code in a Try Catch statement but it doesnt produce an error.
If I set the date to be in the past, I get an error when I try to access the cookie in the same session (presumably because the cookie is expired).
What is the proper way of creating a session cookie ?
Dim UserCookie As New HttpCookie("UserValidation")
Dim RandomClass As New Random
Dim RandomNumber As String
Dim Index As Integer
For Index = 0 To 37
RandomNumber += RandomClass.Next(0, 9).ToString()
Next Index
Dim UserID As String = DataBinder.Eval(Dsuserdetails1, "Tables[users].DefaultView.[0].user_id")
Dim CookieString As String
CookieString = UserID + "-" + RandomNumber
UserCookie.Value = CookieString
Dim ExpireDate As DateTime = Date.Now.AddHours(12)
UserCookie.Expires = ExpireDate
Response.Cookies.Add(UserCookie)

IMHO, the article[^] about the ASP.NET cookie posted here on CP might give you an idea.

There are many ways to get reference to a child control in a data-bound control like the DataGrid, you can see from the link:
http://msdn2.microsoft.com/en-us/library/ms178509.aspx[^]
Also, just curious that you want to use the EditCommandButton, but you also want to hide the Edit button then how you can fire the edit command, or you may consider a template column where you are flexible in controlling the UI.

You can open your webpage in a pop-up that has no buttons no bars and no status bar (you do that with JavaScript; google it becouse there are tons of examples).
But you will still need a regular page with a link to this pop-up.

Hi,
Im using VS 2005 for a .Net 2.0 c# project.
I have a calendar control on the page and have set-up a SqlDataSource to retrieve the required data.
I need to use the calendar to show the title of events happening on any given day. How can i bind the database data to the calendar? Eg the SqlDataSource retrieves all data from the appropriate SQL2005 table. Then as each day of the calendar is rendered any corresponding events, have their title displayed in that corresponding day / date?
Any help would be appreciated!
Thanks
Munklefish.

I am trying to remove list box items dynamically based upon the visible coumns in a gridview. I have a command that can remove columns from the grid but when I execute this I would like it to update the listbox and remove the names of the columns that I removed from it. The code that I have is as follows:
Protected Sub btnUpdate_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim li As ListItem
Dim liNum As Integer = -1
Dim colNum As Integer = -1
For Each li In CheckBoxList2.Items
liNum += 1
colNum += 1
Select Case CheckBoxList2.Items.Item(liNum).Value
Case liNum
If li.Selected Then
GridView1.Columns(colNum).Visible = False
Else : GridView1.Columns(colNum).Visible = True
End If
End Select
Next
colNum = 0
For Each li In CheckBoxList2.Items
If GridView1.Columns(colNum).Visible = False Then
MsgBox(colNum)
ListBox1.Items.Remove(GridView1.Columns(colNum).ToString)
End If
colNum += 1
Next
End Sub
Everything seems to work and I even through in the
MsgBox(colNum)
to make sure that the code is executing correctly and it is. I think my problem is this code:
ListBox1.Items.Remove(GridView1.Columns(colNum).ToString)
Any help would be appreciated.

Can anybody please help on this>>>>>
what is the difference between transfer.exe and transfer.class in .NET
Waiting for ur help

From the information you have given, one can only say this for certain:
They have different file extensions.
And that is assuming that you are actually talking about file names.
If the .exe file is an executable file, it might be a .NET executable. It may also be a DOS program or an unmanaged windows program.
The .class extension is usually used for Java files. If that is the case in this case, it has nothing at all to do with .NET.

When i access aspx pages in that folder it redirect me to Login Page but when I access zip file then it shows File Open Save Dialog and able to download which should not happen.
Please let me know the solutions.
Thanks.

This has been discussed many times before.
There are many solutions. Perhaps the one you would like the most would be to rewrite the URL to some ASPX page.
So if the user types:
http://your_site/download/SomeFile.zip
he would actually access: ../download/download.aspx?File=SomeFile.zip (you can do this in web.config)
and then your authorization settings will apply to that file (your download.aspx file should then output the file to the user).
