Is there anyway to define the screen position after a postback?
Specificaly i'm referring to the vertical scroll position. Some of my controls are set to AutoPostback = True. Depending on their selected value it then reveals a hidden ASP.Net panel and some more questions.
Problem is that with each post back the page refreshes at the top and i have to scroll back down to my question. I can use the .focus() control, that's fine, but it doesn't work as perfectly as i'd like. Is there any way of defining how many lines or pixels the screen is already scrolled to upon postback?

I have two text boxes and one label control. All three controls are in different "td". Now what i want to do is , i am subtacting a value of textbox2 from the value of textbox1 and storing an answer in label control.

View 4 RepliesI have a page with two columns. Initially, the left column will contain a list of links that are article titles. Clicking on one of the links will display the text of the article in the right column, keeping the list of titles in the left column. Clicking on another title will clear the text of the first article and display the second. Is there a way to accomplish this without having to repaint the whole page? I would rather not have the whole page resent each time a title is clicked, but rather have the page stay as is and only the contents of the right column get cleared and redisplayed. I assume there's a way to do this with JavaScript.

I want to change the value of a literal within a repeater ItemTemplate after postback, based on a value detected at postback.I can't render the whole repeater again though I think because it's actually a radio button in the control that inititates the postback and so I need that control / value to be persisted.

I have a gridview with a dropdownlist in one to the headers. So on the onselect event of the dropdownlist I want to change the assigned values of itemTemplate values inside one of the columns.
View 1 RepliesSo, here's the scenario: I have a page in my asp.net c# based website, which displays data dynamically after taking the request from query strings.For example:
Brand=HTC&model=Wildfire
Now, in this page I want to display all the deals available in each network separately.So, on the first pageload, I retrieve the data from the tables of each network that has the requested handset in a deal, store it as a datatable in the cache.I have a datalist for displaying the imagebuttons of the networks that have the deals of that handset. The user will click on the imagebutton of a network to view the deals of that network.
To display the deals, I am using a gridview which retrieves its datasource from the cache. Also, I have provided filtering of the rows through dropdowns in each columns' header of the gridview.All this is inside an updatepanel.
Everything's working fine.
The Problem: I want that whenever the user clicks a network's image button, an image should appear above the gridview, containing the logo of that network.
Things that I have tried: I am storing the networkname in the cache(which also required for filtering the gridview), whenever an imagebutton is clicked. Then, on pageload, I'm doing this:
if(ScriptManager1.IsInAsyncPostBack)
{
Image img = new Image();[code]...
where, nw_image is a tablecell which i'm using to display the selected network logo.and also I've saved the network logos in the images folder as: 'network'_logo.jpg eg: 3_logo.jpg, orange_logo.jpg
The result of this is that when I click a new image button, the image that is displayed is that of the previous network, i.e. the cache is always one postback late.
Right now, the SliderExtender value (when dragged around) will cause a normal postback on TextChanged.
My situation is, the server side code would also like to dynamically change this slider value. When it does this, it changes the sliderextender value by javascript. However, teh problem is, when this happens, another postback occurs raising the OnTextChanged
event when a postback occurs.So how can I change the sliderextender value from the server side withotu raising a postback?
I've tried to set autopostback=false, then set teh value, then setting it back to true but this wasn't workign in javascript.
i want to do postback and do some logical things in code behing whenever user click's Tab other than in which he is presently working.Is this possible? How?

I have a webform containing a user control. On that user control is a set of radio buttons. When the radio button is changed, a panel and a text box is shown or hidden depending on which radio button was selected.I can give you an example that works correctly:testcontrol.aspx:

<asp:ListItem Text="Show 1"></asp:ListItem>

I am building a website in which all of the site layout is in Master page and the content of the site is in the inherited pages. I have various links for navigation in which i simple use Response.Redirect to transfer to different pages. Now the problem is that I want to put the content place holder inside Ajax Update panel so that the postbacks are Asynchronous and I want to show the postback by an animated image inside Update Panel progress control. The problem is that I am unable to achieve this result and the entire page is posted back and rendered again. I have placed the content place holder inside the Ajax control toolkit's Update panel but it does not work. Is there any way that I can change the content of the content place holder to a new page with asynchronous postback.

View 3 RepliesI have a script that runs during the Page_Load() event which checks a database table to make sure that the user is still owns the lock on the page. If they no longer own the lock, I disable all the controls on the page and display an
error message.My thinking was that by disabling all controls during Page_Load() I could prevent any PostBack events from occuring. For example, I have a button on the page called "Save and Quit"

I have a gridview in which I have several editable fields. The user wants a non-editable field to be modified if another field is modified in the same row. e.g. if Age>=65, Status should ="Retired"
I am using the following demo: [URL]
to create a bulk edit gridview so some columns are automatically editable and others aren't, with a single update button. I can set Status="Retired" in the xml generated, or as a rule in database table. But I'd like the status field in the gridview to change when Age is modified and to be shown to user before they press the single Update button. I'm using update panels and ajax on the page also.
