On a page for new users to register, I've placed a asp:wizard control in a updatepanel.Everything is working great, but now I want a new user to upload an image. This however requires a full postback.Is there any way to define the finishbutton of the wizard as a postbacktrigger while the next and previousbuttons remain asynchpostbacktriggers?

I have an button ("export") to export data from grid to excel.
But it's inside an update panel. So I'm registering postback trigger.
What should I assign to PostBackTrigger.ControlId ???
In documentation I have read:
„Use the PostBackTrigger control to enable controls inside an UpdatePanel to cause a postback instead of performing an asynchronous postback."
I made simple application and I do not see difference between using PostBackTrigger and standard postback.
I have three buttons: two inside update panel and one outside update panel. When I click btnUpdateAsync in event handler I set text property of lblUpdatePanel and lblNoUpdatePanel and only lbl that is inside update panel is chaned if web browswer - so this is ok.
Whant I click btnUpdateInUpdatePanelSync all page is refreshed and both lablels are changed in web browser.
When I click btnUpdateOutsideUpdatePanel I see the same behavior.
If I used button that is not associated with PostBackTrigger I would get the same behavior - so what is the purpose of PostBackTrigger?
This is my app:
[Code]....
protected void Page_Load(object sender, EventArgs e)
{
}
protected void LinkButton1_Click(object sender, EventArgs e)
{
}
protected void btnUpdateAsync_Click(object sender, EventArgs e)
{
lblUpdatePanel.Text = "btnUpdateAsync_Click";
lblNoUpdatePanel.Text = "btnUpdateAsync_Click";
}
protected void btnUpdateInUpdatePanelSync_Click(object sender, EventArgs e)
{
lblUpdatePanel.Text = "btnUpdateInUpdatePanelSync_Click";
lblNoUpdatePanel.Text = "btnUpdateInUpdatePanelSync_Click";
}
protected void btnUpdateOutsideUpdatePanel_Click(object sender, EventArgs e)
{
lblUpdatePanel.Text = "btnUpdateInUpdatePanelSync_Click";
lblNoUpdatePanel.Text = "btnUpdateInUpdatePanelSync_Click";
}
In updatepanel we can use triggers with two methods AsyncPostBackTrigger and PostBackTrigger so I want to know what is different between these two as well how can we decide we need to go for which one.

View 3 RepliesI know that UpdateProgress doesn't work with PostBackTrigger, but let me explain what i'm trying:
I'm generating a PDF document (Crystal Report) with ExportToHttpResponse that will be downloaded automaticaly by the browser.
So while the document is been generated, i'd like to show the UpdateProgress just while i'm waiting the doc is being generated, doing the UpdateProgress(or some label) to disappear.
In my UpdatePanel, the user can page, sort and filter a gridview all using AJAX, then they select a row which causes the post to post back and a textbox to be populated with the rows ID.
Problem is, it seems I can't register both an AsyncPostBackTrigger and a PostBackTrigger to the same control - so how would I accomplish this? Here are my triggers so far:

View 5 RepliesI like to handle and compare a lot of date times in my repeater even I have to work more than one time with the same.
It's a bit ugly, to cast everywhere the Eval("MyDate") like ((DateTime)Eval("MyDate")) to substract 2 datetimes or to compare it, even if you have to do this more than in one operation.
I thought of saving all the evals in a var at start of the repeater?
DateTime mydt1 = Eval("myDate");
DateTime mydt2 = Eval("mydate");
after that, it's easy to do any operations in the whole repeater. Hope you understand my idea. Is this possible? I tried short but everytime errors.
mydt1 - mydt2....

View 5 Replies to define a variable/property of more than one type. Let's say i want a property TextWebControl that is a WebControl and also implements Web.UI.ITextControl(f.e. like a TextBox or Label). But i don't want to enforce that it is a TextBox or Label, but only one that inherits from WebControl and also implements ITextControl so that it also would work with controls added in future releases of .Net-Framework.

Edit: I have retagged the question and added VB.Net because it's my default language. Normally it's no problem for me to understand C# also, but i must admit that it's difficult to translate generic stuff to VB.Net without experiences and it's also better documentated in C# than in VB. So i would appreciate(and aceept) a working example of a VB.net generic type of ITextControl/WebControl.
From Marc's answer i understand that i need a generic class. But how do i instantiate it in SomeClass? This won't compile:
Class SomeClass
Public Property info As InfoControl(Of WebControl, ITextControl)
End Class
