Disable a post back from asp.net i.e. buttons, links, gridview page index changing and sorting etc when a post back is already in progress. Target browser is IE 6+. I've written these 2 javascript I am not sure how to apply it on GridView Page Index changing.
[Code]....
But I am not sure how to attach the VerifySubmit to non prompting controls like gridview pager.
I have four textbox and a button in my page. After filling the textbox. When the user click save button. A loading image should be displayed. User should not feel that the page is postback to the server,Some thing like in facebook loading image.
View 5 RepliesBeing new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).
Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?
Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

I have the following code on my website:
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<asp:UpdatePanel runat="server" id="UpdatePanel" updatemode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger controlid="myButton_btn" eventname="Click" />
</Triggers>
<ContentTemplate>........
The javascript is running everytime I click the button. However, even though my subroutine updates the session variable after clicking the button, I always get the same alert. In other words, the same javascript is run after postback, and it is not updated. I am positive that the session variable IS being changed.
I have created a listbox that the selected items would remove by using javascript once I clicked on a server button. Below is the code I'm using
<asp:button id="btnSelected" Runat="server" CssClass="InputFormObject" Text=">" ></asp:button>
<script language="javascript">
function removeOptions(selectbox)
{
var i;
for(i=selectbox.options.length-1;i>=0;i--)
{
if(selectbox.options[i].selected)
selectbox.remove(i);
}
return false;
}
</script>

Is it possible to manually fire a AJAX postback from Javascript.
View 4 RepliesThis is what I have implemented, for further code, how to send the text of the text box to the server to store in variable or database without post back? It can be done by using Ajax and update plane, but I would like to implement it using a JavaScript script.
<div id="CommentID" style=" width:30%; height:30%">
<asp:Button ID="Button1" runat="server"
Text="Comment"
OnClientClick="visibleDiv('id1'); return false;" />

I have multiple update panels in a page. how I can know which update panel caused partial page updation on client side before page is partially updated?
View 3 RepliesI have put the following method in my master page. It works when I call it on a full post back, but when I call it from a updatePanel's asyncPostBack no alert is shown.
public void ShowAlertMessage(String message)
{
string alertScript =
String.Format("alert('{0}');", message);
Page.ClientScript.RegisterStartupScript(this.GetType(), "Key", alertScript, true);
}
What do I need to do so it works on partial post backs?

I have a dynamic data bound drop down list, when the user selects thier selected item I have to use the autopostback feature.
Problem is: when the page comes back it is at the top of the page not where i have the control.
I don't really need it to focus back on the dropdownlist but to scroll to it, I want to do it in the code behind.
Any "New" ways to do it, I mean new as in code from like 2010 instead of old code from the early days.
I really don't want to use Page.Register new Script...... code if I can avoid it.
What would be cool is a ScrollToControl() Function for my code behind that worked but didn't register script.
I have a very odd and disconcerning problem. Just recently a page where I have 1 textbox and a buttoon has ceased to work.
When I look at the post coming into the PageLoad, the pageType is "POST", but the Page.IsPostBack is false!! and the textbox (which had content) is empty.
I have stripped all AJAX script out, so I have a very vanilla page (in a master page) being served.

I am using Attributes.Add("style","color:green") with some checkboxlists and radiobuttonlists. When I click one of the checkboxes and I do the autopostback the attributes clear out. So I would think someone already has a sub to fix this. Something like:
SaveAttributes(checkboxlist1) or SaveAttributes() 'which would loop though all controls and save the state.
and then on pageload it would have
LoadAttributes(checkboxlist1) or LoadAttributes() 'which would loop through all controls and restore the state.
