I have a situation where I want to evaluate a record to make sure it fits a specific set of criteria. If it fits the criteria, raise an alert message for confirmation from the user. I do not want to raise the popup unless the criteria matches.

I'm having few UpdatePanels on my master page. And then, I have RadTreeViewcontrol on the page, that should cause partial postback each time node is clicked. Everything works fine there.
Since I'm using the same tree on some other pages, I moved this functionality to UserControl. Stuff I've done before, so no problem. Moved some code to ascx, created some events. Everything always worked for me well. But not now.
RadTreeView is nested inside UserControl, and this control on master page with update panels, see below:
<asp:Panel ID="pnlContentWrapper" runat="server" CssClass="ContentWrapper">
<div id="HeaderBreadCrumb">
<asp:ContentPlaceHolder ID="HeaderBreadCrumbContent" runat="server" />
[Code]...
What I don't know is: why is this causing full postback instead of partial? I suspect that it may have something to do with raising my for SelectedNodeChange, but I don't know how to deal with it other way. I need to let other components know, that node selection changed. How can I improve this to make it work with UpdatePanels?
When an UpdatePanel Calls a method in server and for example this method change textBox1.Text = "12312"
and this textBox1 was out of updatePanle scope it dosn't change it text till a postback happend to the page
so I need after that calculation and chaging the Textbox's text in the server, I need to forcepage to do postback
I have a content page linked to a master page. The master has the toolkitscriptmanager. On the content page, I have a nested repeater within the item template of the parent repeater, I have a CollapsiblePanelExtender for the child repeater control. Upon partial postback, if the collapsed attribute is not set, then all of the panels expand. If the collapsed attribute is set to true, then all of the panels are collapsed upon partial postback.
The databinding of the repeater is occurring in the page_init section of the code behind, and I am checking the state of the panels by iterating through the items in the page_load event. Nothing appears to be working, while debugging the code, I do see the properties being appropriately set, but when rendered in the browser, all panels are open. The edit event that triggers the partial postback is preformed in a modalpopup.
I have attempted to move the panels into their own update panel, remove the update panel, place the modal outside of the update panel to no avail. The ViewState is not maintained.
Page Code:
<asp:Repeater ID="rptrConsultants" runat="server" OnItemCommand="rptrConsultants_ItemCommand" OnItemDataBound="rptrConsultants_ItemDataBound">

I am trying to trying to setup an updatepanel to update every X seconds, the problem is I don't want the control to actually refresh unless there is new data. So I currently have a child updatepanel in a parent UpdatePanel, the child updatepanel gets refreshed by a timer. But I can't seem to find a way to trigger the parent panel to update. Again, only when certain conditions(data changed) are met.
Sample Code:
<asp:Timer ID="Timer1" OnTick="Timer1_Tick" runat="server" Interval="10000"></asp:Timer>
<asp:updatepanel id="upParent" runat="server" UpdateMode="Conditional">

I have an update panel that has a timer set as the AsyncPostBackTrigger.In this Update Panel I have a repeater and in the repeater I have a few buttons which have on click events.
The on click of these buttons does not appear to fire until the timer has ticked.I have tried debugging and this is what seems to be happening, either way it takes ages for the button click to actually fire.
Does anyone know why this would be and what I can do about it?

View 1 RepliesBasically the cells are displayed from Excel to the Visual Basic form, but once I press a button on the form to display the spreadsheet which contains the cell info, the spreadsheet won't display at all. (This I think is because the link has subsequently already called Excel). I've looked at the Task Manager and copies of Excel are already in the process, once these are deleted the spreadsheet can display from being pressed from a button on the form. How can I override this deletion method from the task manager so that the spreadsheet always displays properly from the form.

I am working on a Text editor. The problem I have come to, is that when a user clicks a button, I want all the text to be displayed on one line. The reason for this is I am having problems being able to upload CSV email files on a website I am working on, because the format isn't like email, email, email, email. Instead it is like
email,
email,
email,
So I have written a program that will format it. Only It still isn't working. I need it to recognise when there is a ".com," or something.
