When a user clicks a control that has autopostback=true, the screen refreshes and scrolls back to the top of the page. Is there a way to avoid this and have the page stay in the position it's in?

View 1 RepliesI'm using VS2005 / VS2008 and MSSQL RS 2005 + ReportViewer v.8 or v.9.
Problem: when user makes drillthrough click on "plus sign" on Matrix row postback occurs. Then scroll position is lost! It scrolls to the top of the page. It's very bad for report users.
The most interesting thing is that it happens only within ReportViewer! I works acceptable if I open report via "localhost/ReportServer/Pages/ReportViewer.aspx?..." . It's based on something similar to ReportViewer :

And it remains scroll position well!
Is there a way to make ReportViewer working correcly? (remembering scroll position on Matrix row drillthrough postback)
I read that Report Viewer 10 (of VS 2010) will lack this issue but it doesn't support MSSQL 2005 which I plan to use so far.

Why does microsoft make objects in .NET with incomplete behavioural methods, then expect everyone to use a client side "language" to help complete the methods? I don't wanna have to use Javascript to keep focus on my leaf node in my TreeView after clicking it. I want a server side answer to my question, but if that's impossible I guess I can run ANOTHER javascript bandaid to do this, since I guess Microsoft doesn't have a solution. Oh and By the Way if your going to post an answer please remember I'm using WEBFORMS not WINFORMS. God help people who try to run my app (or any .net app) and don't have Javascript enabled on thier browsers. Does Microsoft own Javascript? Maybe since they rely so heavily on help from the client side to achieve behaviours, they ought to think about acquiring it.

View 5 RepliesI'm using ASP.NET, and in a Wizard control I have radio buttons where if "Yes" is selected, a panel is shown, but if "No" is selected, the panel is hidden. I have MaintainScrollPositionOnPostBack set to True, though the ActiveStepChanged event changes it to False so that when you click Next to see the next Wizard step, it will start at the top of the page. The problem is, after clicking Next, the first time you click on a radio button it jumps to the top of the page (the page retains its position any time you click a radio button after the first time). How do I stop it from jumping the first time?

View 1 RepliesI've got a TextBox with AutoPostBack="true" and OnTextChanged property set.
The textbox is located inside a Repeater, which in turn is located inside an UpdatePanel.
Problem is - whenever the TextBox postsback, the whole page gets reloaded, instead of the UpdatePanel only.
Here's how the thing looks:
[Code]....
Interesting thing is, if I take the TextBox out of the repeater, it refreshes only the UpdatePanel. So is if I put a Button inside the repeater - only the UpdatePanel gets refreshed. But whenver I place an AutoPostBack-ing control inside the Repeater, the whole page gets refreshed.

i duno why, when i put a autopostback in my drop downlist, after the postback, my content HTML editor and the flash button all disappear.
i have put the enable view state = true. but it still happen.
I am an asp.net newbie and encountered problem with postback. I have created a web form and put some web controls and set their AutoPostBack property to True.
Some of the controls are listbox, checkbox. However, the SelectedIndexChanged and OnCheckChanged do not fire automatically when an item is selected from the listbox for example or when the checkbox is checked. I noticed that the commands I put in the SelectedIndexChanged and OnCheckChanged is only fired when a button is clicked.
e.g. The code below that sets the text of a label is being fired only when a button is clicked even if the autopostback property of the listbox is set to TRUE.
protected void ListBox1_SelectedIndexChanged(object sender, EventArgs e)
{
ListItem myItem = ListBox1.SelectedItem;
Label1.Text = myItem.Text;
}
Again, I would like the Label's text to change when an item is selected from the listbox and not only when a button is clicked.
What else could I be missing to make autopostback work?
I have a gridview with checkboxes going down the side for each item. Some are enabled and others are not. At the top of the page is a checkbox which when checked will make all the checkboxes on the side enabled. THis is not working and I have tried 2 variations. What am I doing wrong?

View 6 RepliesIs there a way to have a textbox autopostback when the 5th character is entered into the textbox?
I have a zipcode textbox that I would like to fire an autopostback as soon as the 5th character is entered. Currently I have it so it will fire when tabbed out of or when the next textbox is clicked in but it would save one step for the customer if it fires on the fifth character.

I have a webform with multiple input textboxes. each box is used in computing somethings, and i am doing these calculations within the TextChanged event for each textbox...this way after the user enters each entry, all calculations requiring that data is performed. I have also set EnableViewState="true" and AutoPostBack="true" cause I am trying to have the textbox keep their data displaying on AutoPostBack. The form is not behaving the way I want it to...right now, if a user inputs data in one field and switches focus to the next, the previous box losses it's data. Is there a way i can get this behaving the right way? I basically just want all the controls to keep their data on AutoPostback.

I have a nut for a manager who changed my form and added _top so that I could redirect a response to a parent window, anyway, I have two .net forms and now he tells me I can't do any posting back on my child window. I have lots of .Net event callbacks that use autopostback on this child window. He told me he believes I can do all the necessary event code through his Javascript client-side scripting that he loves so dearly. I don't think he knows .NET very well even though he acts like he does. the microsoft server coding world and without replacing every object in my child window (there are many) with html and resorting to an html page (God help me Bill Gates I'm coming to get you) is there anyway I can have my events (onselectedindexchanged onclick ... ie) to call javascript functions without an autopostback on any of my controls ?

I have controls and some has AutoPostBack set to true.
i.e
<asp:CheckBoxList ID="cblTest" runat="server" AutoPostBack="true"
OnSelectedIndexChanged="cblTest_SelectedIndexChanged" >
</asp:CheckBoxList>
How can I capture which control has triggered the autopostback event when it runs again in the Page_Load method.
How to give a label Autopostback abilty
what i tried is lblarr.Attributes.Add("AutoPostBack","AutoPostBack");
I've got a server control that renders out a series of dropdownlist and a checkbox that all have autopostback set to true. When the control renders the onchange event binding is not written out!
Controls are defined as protected, named and added to the controls collection in OnInit, and rendered via RenderControl(writer). Page.requiresPostback is also set.
ANy ideas why this might be? I'm scratching my head.
