You cannot directly set the Session data with javascript, instead you may consider using AJAX and you can easily find lots of examples out there.

You can store in Cookie instead of session. You can set cookie value from javascript and also from asp.net code.

The best bet is to store it in a HiddenField control, then document.getElementById to retrieve it on the client side

What do you mean by this?

srinandan.. wrote:

Why do you check the SqlDataSource instance?

What I said in the other post is to use the Selected[^] event of the SqlDataSouece control, and do a checking on the e.AffectedRows.

Server.GetLastError() not working [modified]

Hi all,

I am running ASP 2 on IIS 5.1 XPPRO and I have enabled customErrors, so i though i would see how they look locally and set mode=On.

this is the code that fires the exception:

protected void AddToQuoteButton_Click(object sender, ImageClickEventArgs e)
{
  try
  {
    Guid guid = new Guid(Request.QueryString["id"]);
    QuoteManager.AddToQuote(Page, guid);
  }
  catch (Exception ex)
  {
    throw new Exception("Illegal Product Code in query string.", ex);
  }
}

and this is the custom 500 error page logic

public partial class _500 : System.Web.UI.Page
{
  protected void Page_Load(object sender, EventArgs e)
  {
    if(Server.GetLastError() != null)
    {
      string error = Server.GetLastError().Message;
      ErrorLabel.Text = error;

      Server.ClearError();
    }    
  }
}

so i load a page which requires a Guid on the querystring (but i chop some of the guid off) then click the button whose handler is above, and it goes to the 500.aspx page but Server.GetLastError() is always null.

note: it is suppose to go to 500.aspx on load but i disabled that to do some testing.

why is this?
kind regards,
g00fy

this is the web.config section

<customErrors mode="On" defaultRedirect="~/500.aspx">
    <error statusCode="404" redirect="~/404.aspx"/>
</customErrors>

Try above code in Page_Error event, rather than Page_Load

It always return null in Page_Load

Hi there,
In this case, you need to manage to redirect to the error on your own by using the Application_Error in the Global file with the Server.Transfer method. You can see the sample code from the link:

Multiple Insert without postback

My problem is like this.

In a page i have controls to add contacts

FirstName 
Lastname 
Address
Zip etc..

The page has two buttons "Add" and "Save"

+ on clicking Add button the content in the controls need to be stored temporarly in client client. And listed in a table below. Its also possible to delete an item from Added list.

+ on clicking Save all contacts stored temporarily need to be submitted to server and update to the database

means post back must occur only on clicking "Save"
How to do this. It must support cross browser.

Private dt As New DataTable

In Page_Load event

If Not Page.IsPostBack Then
dt.Columns.Add("fName", GetType(System.String))
dt.Columns.Add("lName", GetType(System.String))
viewstate("dt") = dt
End If

In btnAdd_Click Event

Dim dt As DataTable = viewstate("dt")
Dim dr As DataRow
dr = dt.NewRow
dr(0) = txtFname.Text
dr(1) = txtLName.Text
dt.Rows.Add(dr)
DataGrid1.DataSource = dt
DataGrid1.DataBind()
viewstate("dt") = dt

On Save Click, You should get table from viewstate variable and store data in database

If you don't want a postback to occur when clicking the add button you can either use some javascript to save the values to a hidden field or use AJAX to place them in temporary storage (session, database...) until the save button is clicked.
