Being 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.

View 2 RepliesI have a custom server control (composite control having dynamically created dropdown boxes and textboxes). I have enabled AJAX in order to avoid page reload.The server control is used inside the ASP.NET webcontrol having few buttons which controls the visibility of the server control. Now I enter values in the dropdown box and texboxes and click on any other button. After this postback the last entered values are gone! The control is not remembering the values. How can I retain the values after post back?
View 4 RepliesThere is a drop down list in the jquery ui modal form with id - drpAction.When the selection is changed I need to execute drpAction_SelectedIndexChanged function in the code behind. When I just try to invoke the function like onSelectedImdexChanged="drpAction_SelectedIndexChanged" ,the function is not fired.
View 1 RepliesI have a button like this:
<asp:Button ID="btnSave" runat="server" ClientIDMode="Static" Text="Save" OnClientClick="return ConfirmSave();" OnClick="btnSave_Click" />
If I write my client function like the following, it works as expected:
function ConfirmSave()
{
return confirm('Confirm?');
}
But I should check, inside the function, for the confirm result, like this:
function ConfirmSave()
{
if (Page_ClientValidate('validationGroup'))
{
var conf = confirm("Confirm?");
if (conf)
{
$('#btnSave').attr('disabled', 'disabled');
}
return conf;
}
else
return false;
}
Doing this, the page postback but the server click event doesn't fire.
i create a user control
this user control have tree input type text
i can save a input value when a postback fire in page but i want
save all input value in post back
can i save value of more than one property of a server control when a bost back fire.
ASP.NET Ajax Library provides some client-side events. For instance:
Sys.Application.add_load(
function(args) {
// handle the end of any asynchronous post-back. Every-time there's
// a server round-trip, this method will be called.
}
);
During the asynchronous post-back I want to retrieve information to the client. This information must be available in some event like the discribed above.
Does the UpdatePanel or the ScriptManager have any server-side way to retrieve data back to client during an asynchronous post-back?
I 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?
Using Vb.Net 2003 Asp.Net 1.1
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.
The pages is

The page is "POST", but isPostback is false[Code]....

- How do I get postback values from Rad/components ?
- How do I get postback values from Rad/components when they are in user control ?
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.
