I have a survey, where you have to click through several pages with questions. I use a "Next" and a "Previous" button for doing this. I use a session for keeping tabs on my position. However, this is a problem.
I use the button_click event to increment the page counter, but since this fires after the page_load event, nothing happens on the first click, and for every click thereafter everything is one page behind because the questions are rendered before the counter is incremented.
Is there any way to solve this without using the query-string?

My understanding is that the following happens:
The first page loads and the counter is not set. The counter is set to 1. The first page is displayed. The user clicks the "Next" button, firing a postback. The page loads, displaying the same set of questions, because the counter is still on 1. The buttons Click-event is run, incrementing the counter. However, the page is still displaying the old questions.
After this everything is one page behind because the questions are rendered before the click-event is fired, incrementing the page counter.
Following is the structure of the pages in application

Suppose the user is on ..../paycheck.aspx which is the content page. But when ...../paycheck.aspx loads, "lnkDynamic" properties "Text and PostBackUrl" must be set. Which events should be handled .....
I am having problems selecting the text within a TextBox in an UpdatePanel in IE 8. Consider a very simple page that contains a single UpdatePanel. Within that UpdatePanel there are two Web controls:
A DropDownList with three statically-defined list items, whose AutoPostBack property is set to True, and A TextBox Web control
The DropDownList has a server-side event handler for its SelectedIndexChanged event, and in that event handler there's two lines of code:
Let me set this up:I have a master page. I have a regular aspx page - this page contains a Menu and a User Control.When I click on the Menu Item, it fires my click event. This will post back. The Master Page Uses Placeholder Controls where I dynamicaly create Label Controls with information and add them to the Placeholders. These contain data with tooltips. This works great. After the Master Page and Web Page load, it will then fire the Click Event from the Menu.The problem:The Click event will update data in the database, This data may effect the values that are created on the Master Page that are placed in the Placeholder controls. I can't seem to figure out how to change that data.
What I have tried:I have created a reference to my Master Page on my Web Page. In the Click Event after I have made changes to the Database, I call the function on the master page that Creates all the data and places them in the place holders. It Runs, but nothing changes on my page.Am I going about this wrong? Is there another way of doing this? I terrible work around, would be to just reload the whole page after I do an update.
I have two dropdownlists on my page that are related to one another, and are built dynamically. I did not write the original code, but I believe it is using AJAX so the whole page doesn't postback when the ddl selection changes. The first ddl is Status and the second is ContractType. Here is the code for the event handler:
I commented out the event handler since this snapshot, just to see what would happen, but when I was hitting it you can see what ex.Message was. I don't understand why it says the SelectedValue is invalid when I see the selected value is "E " and that is one of the four items in the ddl.
In my page I have a read-only TextBox that contains a rather large amount of text. I noticed that on postback this text is sent back to the server and validated, even though the client can never modify it. This seems silly; is there a way to disable this behavior?
I have a GridView control which contains a custom <pagertemplate> with a <asp:PlaceHolder runat="server" ID="plcPages"> control. The .aspx.cs file contains the following code: protected void Page_Load(object sender, EventArgs e) { ... {Other Code} ... GridViewRow pagerRow = GridView1.BottomPagerRow; PlaceHolder PagePlc = (PlaceHolder)pagerRow.Cells[0].FindControl("plcPages"); Button btnPage; int iPageNum; for (int i = 0; i < GridView1.PageCount; i++) { iPageNum = i + 1; btnPage = new Button(); btnPage.ID = "btnPage" + iPageNum.ToString(); btnPage.CommandName = "Page"; btnPage.CommandArgument = iPageNum.ToString(); btnPage.Text = " " + iPageNum.ToString() + " "; PagePlc.Controls.Add(btnPage); } }
Everything works fine the first time the page is displayed. But, when I click any pager button, including the Next and Prev command buttons that are not part of the PlaceHolder, the contents of the PlaceHolder are never re-displayed. I know from searching other posts that the PlaceHolder contents are lost during the trip to the server, but I am already recreating them every time the page is loaded. They are just never being shown again. I've spent the last two days playing with ViewState And every other combination.
I have used Session.SessionID property, but it's keep on changing on every page postback.....can we keep it same untill user sign out from his account..?
what I want to do is when the user enters values on the page I want to be able to change "valueA" and "valueB" in the URL without redirecting, refreshing or posingBack. Does anyone know how to do this?
I have a search page with a TextBox that allows someone to type in a search term and press enter. (Which fires TextChanged). I have a DropDownList that specifies the kind of search that will be performed. It is defined in the markup as follows:
As you can see, AutoPostBack is set to false, and there is no event hookup.
Pressing enter fires the OnTextChanged event for the TextBox, which performs a search and updates a GridView in an UpdatePanel. This UpdatePanel has its UpdateMode set to conditional and has one trigger: the TextChanged event of the search TextBox.
It's very simple.
And it works beautifully, almost.
Whenever I change the search type, the very next search does a full postback. All subsequent searches do partial postbacks (as desired) unless I change the search type again.
There is one exception to this rule: if I load the page and immediately change the search type, it doesn't do a full postback. So the first change of the DropDownList before any postback (full or partial) does not trigger a full postback.
Full Disclosure: I'm doing a lot of JavaScript to change the appearance of the gridview during async requests. I don't detail it here because it seems unrelated. This problem only occurs when a DropDownList with no JavaScript wired up is changed.

I created my page with asp dropdown. On selected index changed I am seeing postback operation on dropdown. I couldn't avoid postback operation of asp dropdown with updatepanel also.
IS there a another way to avoid dropdownpostback operation.
I have created a really simple custom control to render panels into a page. The code is below. When I use my control and add any webcontrol to it, after each page postback the contents of these child controls vanishes.
I must have missed something really simple but run the example to reproduce this. Can anyone please enlighten me as to why the controls are being 'emptied' of their contents, and how I stop this occuring?
I'm trying to create a page that displays a databound gridview to the user showing them the items being processed. Then the page should immediately begin processing. The problem is that the page never shows the gridview (or any other control) until the process is complete. The process is being sent to a WCF service. I've tried setting the page to async and running the wcf in async mode but the content still fails to display.
