OK, I'm fairly green with ASP.net and I keep running into the same problem and I've solved it in various ways but none to my satisfaction.
What I want:
- To be able to click on a button/link or choose an option from a dropdownlist and have a tab be updated immediately with data supplied by the event set off by the button/link/dropdown.
What I can do so far:
- First click updates the tab and *then* sets the necessary variables that my tab needs to update properly. A second click re-updates the tab correctly.
So, I use the OnClick event (or similar) of the button to set Session variables (values of which may come from a db) that the tab's OnLoad event needs to load itself properly. Unfortunately, the OnLoad of the tab happens before the OnClick of the button.
Question:
- What is the standard, non-javascript, way of making a C# function happen before the button engages the OnLoad event? Preferably I'd like the OnLoad to only happen once, but if the only way is for the thing to be set off twice, I can live with that.

google ASP.NET page life cycle. The on load event will ALWAYS occur before the On click event. Once you understand the cycle better it will help you rearrange your code to fit it to get the desired results

That's my question: How *do* I rearrange my code to fit the desired result?
Or, is there some AJAXy thing I can do to the button that will allow code to run first and then load a control?
(I should have mentioned that I have looked at the page lifecycle and I still have no idea how to accomplish what I need. My workaround so far has been requiring a selection of an item (datagrid selection, dropdown selection, etc.) and then a button click to confirm the selection.)

You had not indicated it was in a ajax call. Typically when an item is not updated in a ajax call even though you attempt to on the server side, the item that does not update isn't in the ajax container that is being updated and therefore doesn't change on the client but the server thinks it has still. A 2nd postback reveals the change.

Well, in this case, the problem is that I click the button and...
1. The tab, I want updated, gets updated with old information thanks to obsolete session variables and whatnot.
2. The C# code executes - changing the session variables to the values I need (the values being decided by which GridView row the user selected and/or by querying the db).
Result: A tab with old information.
What would I need to do to recover the correct values I need and then update the tab with one click/selection?

make sure the tab is part of the ajax update. Make the changes in the onclick event. Is the tab in a update panel that is updated by the button? If not your changes will not be visible until another postback occurs. On sucessful execution of a ajax call, only items in the panel for that update change on the client. The server side viewstate however is updated with all changes. When a 2nd post back occurs, the changes from the viewstate end up showing on the client. I don't know how to be more specific.

I think I'll be able to figure it out from there - thanks for all the help.

I have a collection of 50 textboxes. I was wounding if it is possible to run a TextChange Event on a collection of textboxes instead having to add each event handler in individually.
The code behind is VB

Hi,
If the text boxes are not dynamic then it is very easy to make that as :
<asp:textbox id="TextBox1" runat="server" ontextchanged="TextBox_TextChanged" autopostback="True" xmlns:asp="#unknown">
<asp:textbox id="TextBox2" runat="server" ontextchanged="TextBox_TextChanged" autopostback="True" xmlns:asp="#unknown">
so on and so forth ....
in code behind
protected void TextBox_TextChanged(object sender, EventArgs e)
{
TextBox txt = ((System.Web.UI.WebControls.TextBox)(sender));
}
you can easily get which textbox changed event is called
Regards,
Milind

U must have assigned ID to all of ur textboxes whether u create it dynamically or us it beforehand as a static control
so u can create a centralized event handler for all ur textboxes
for eg. if i have two textboxes with their ID as say t1 and t2 respectively then
i will use this method to act as a centralized event handler for textchange d event of both as
void TextBox_TextChanged(object sender,EventArgs e)
{
TextBox t = (TextBox)sender;
switch(t.ID)
{
case "t1": Response.Write("Text Changed in t1");
break;
case "t2": Response.Write("TextChanged in t2");
break;
}
}

Hi,
There are two ways you can do that.
1. If you are using Ajax Updatepannel then, you can easily get info from site
http://www.asp.net/AJAX/AjaxControlToolkit/Samples/HoverMenu/HoverMenu.aspx[^]
2. if it is normal Aspx page with no ajax then, on each rowbound write code for mouse hover attribute
eg.
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Attributes["onmouseover"] = "this.style.cursor='hand'";
e.Row.Attributes["onmouseout"] = "this.style.textDecoration='none';";
}
you can also call javascript on onmouseover attribute.

Milind

Thanks for the reply, i have gone through the URL given by u. but the thing is i want to bind ditterent data for different rows. so how can i do that .
Naina

Hi,
In that case, you can write a javscript function on onmouseover attribute, and in "Opendiv(para)" javascript method you can pass row index and show the appropriate data in DIV control.
protected void gridview_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Attributes["onmouseover"] = "javascript:OpenDiv(" + e.Row.RowIndex + ");";
e.Row.Attributes["onmouseout"] = "javascript:CloseDiv();";
}
}

Milind

Hi,
Please set the 2 parameters before sending SMTP MailMessage :
message.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport", "25");
SmtpMail.SmtpServer = "Server name"; //please specify your mail server name
Again, check the anti virus setting for the smtp mails.

Milind

So, you need to put that part of code which is not working and you think relevant, rather than putting all those line.

Are you sure localhost is your SMTP server IP ? and if yes , then is it configure properly? Make sure !!

Hi,
Just Test the mail by using following code
add following in directives
Imports System.Web.Mail
and write following code :
Dim mymsg As New MailMessage()
mymsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport", "25")
SmtpMail.SmtpServer = "mail.wunderman-amman.com"
mymsg.From = "test@test.com" ' from email id
mymsg.[To] = "test@test.com" ' to email id
mymsg.Subject = "ATICO Newsletter"
mymsg.BodyFormat = MailFormat.Html
mymsg.Body = "test"
SmtpMail.Send(mymsg)
