Set a session variable to pre defined value

I just want to set a sesison variable to a defined value when a page loads, I've tried the following but it doesn't seem to work. Any ideas where I'm going wrong?

<%# Session("var1") = "abc" %
Thanks

Julian ParkinsonYou've used adata binding expression, so it will only be called when DataBind() is called on the Page.

I think you want to use aninline code expression instead:

<% Session("var1") = "abc" %>

Hi,

You need to put the Session variable in the Page_Load like this:


 if(!Page.IsPostBack)
{
Session["Name"] = "NewValue";
Response.Redirect("Mynewpage.aspx");
}

And then in the Mynewpage.aspx you can recieve the session using this code in the Page_Load with not postback.

if(Session["Name"] == null )
Response.Redirect("LoginPage.aspx");
else
Label1.Text = Session["Name"].ToString();

Dan,

Cheers for that. I just needed the remove the hash!! Duhh!

I'm moving from asp vb to asp.net vb and i'm finding it strange, some stuff is the same, some isn't sometimes I can't see the wood for the trees.

Thanks again.

Just jam a little

in there and you should be okay.
BTW, I had some problems with your markup. My fixed version is below.
Does this help?

BTW, here's the code behind and data source that I used for that example.
"Boolean" is the name of the field as well as the type.
Private Sub Page_Load _
(ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles MyBase.Load
MyGrid.DataSource = CreateDataSource()
MyGrid.DataBind()
End Sub
Function CreateDataSource() As DataTable
Dim dt As New DataTable
Dim dr As DataRow
dt.Columns.Add(New DataColumn _
("IntegerValue", GetType(Int32)))
dt.Columns.Add(New DataColumn _
("City", GetType(String)))
dt.Columns.Add(New DataColumn _
("CurrencyValue", GetType(Double)))
dt.Columns.Add(New DataColumn _
("Boolean", GetType(Boolean)))
Dim i As Integer
For i = 0 To 8
dr = dt.NewRow()
dr(0) = i
dr(1) = "Item " + i.ToString()
dr(2) = 1.23 * (i + 1)
dr(3) = (i = 4)
dt.Rows.Add(dr)
Next i
Return dt
End Function 'CreateDataSource

Set focus to a textbox on page load

I am new to ASP/ASP.NET so kindly be gentle. When my index.aspx page loads, I need the focus to be on one of the textboxes called txtUserName.

I come from a VB background, so expecting the obvious, I go to the Page_Load event of the index.aspx page and try to write txtUserName.SetFocus but I see there isn't a SetFocus method for the System.Web.UI.WebControls.TextBox class.

What's the way to set the focus to a textbox on the page load in ASP.NET?take a look at this thread:

http://www.vbforums.com/showthread.php?t=316582&highlight=textbox+focus
Hi , You may use a java script

<SCRIPT LANGUAGE="JavaScript">
function setFocus()
{
document.Form1('TxtCno').focus()
}
</SCRIPT>

and call it in

<body MS_POSITIONING="GridLayout" bgColor="#003366" onload="setFocus();">


thats it it will focus the cursor on your desired field
