I've googled etc... but can't find anything relevant.
I have a user control in a master page.
The user control access a session variable which may or may not exist.
If it doesn't exist, the user control doesn't display any content. If it does exist, it displays content.
The problem is that when a page creates the session variable in the postback, the user control is already created and at the time the user control code ran, the session variable didn't exist. This means that although the session variable exists, the user control is not displayed until the user navigates to the next page.
Is there any way to force a user control (which is in the master page) to load after the page code has run?
Thanks

You can have a method in your usercontrol to reread value of session variable. You can call this method in your code after you write value to a session.
Or you can override Render (or OnPreRender) method of your user control to reread session variable.
These methods are called after postback handlers, so your variable stored in session should already has desired value.
I like this solution more.
class MyControl : UserControl
{
...
...
...
protected override OnPreRender(EventArgs e)
{
// read value from session
SetContent(Page.Session["MY_SESSION_VARIABLE"].ToString());
base.OnPreRender(e)
}
}

It sounds like your browser is timing out before the upload has time to finish. You could try displaying an "uploading" page whilst the upload happens, though without your code it is diificult to say exactly what is going on

i use i use
HtmlInputFile.PostedFile.Write Method

You can use var elem = document.getElementById(id) to retrieve your text box element, then use elem.value = "whatever" to set its value.
See if you can figure out how to trigger the code. (Hint: you're probably wanting to investigate keyboard events for the text box element)

You have to get the id using the same connection that you used to add the record.
---
b { font-weight: normal; }
|
|
|
|
|
If you want retrieve @@IDENTITY in MS Access you can use this function after inserting record in database : "Select Max(FieldName) From tableName"

Hello All,
I am working on ASP.NET 1.1. I am using a Panel control to add some controls at the runtime. Now the problem is that when the page displays, the panel moves to the bottom of the page. I have the panel in a table, but it moves out of that table and goes to the bottom. I am screwed up by this issue. Any help is very much appreciated.
thanks,
Mubashir

I am builing a application,there are different type of roles like administrator,guest,user and
i want to display only certain features certain users based on Roles how do this in GUI in ASP.NET 2.0 .Thanks in advance

This is quite wide topic, but generaly you need to have Role class with method IsUserInRole(...),
then you can display/hide controls in accordance with what this method returns. Do not reinvent wheel, see .NET Provider model:
