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.
I 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.
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.

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.

View 2 RepliesI have two Repeater controls, each hosted in a user control. Both user controls are contained in the same aspx page. Only one User Control is visible at any one time. The repeaters are comprised of checkboxes, and text boxes for user input.
The aspx page is configured with an Ajax ScriptManager; and contains several Ajax UpdatePanels. These UpdatePanels result in partial page post backs when text is changed in a textbox control in controls on the aspx page (this is not the behaviour for the Repeaters in the User Controls). Through use of several AsyncPostBackTriggers, various controls contained in the other UpdatePanels on the page have their content refreshed in response to the partial page post backs they are configured be notified about.
Depending on a radio button group selection, I set the visible property to true or false - as appropriate for the User control containing a repeater control. The Repeater control is then populated with data using databinding. All of this works.
However, when the Submit button is clicked, the Repeater control contains no data.
Given that I am not dynamically adding the Controls containing the Repeater controls (but using Visible true / false). I would have thought that the State of the fields and the data in the visible control would be preserved during the post back.
The User Controls are contained within the UpdatePanel that contains the Submit Button.
I have explicitly Enabled View state without any effect.
Am I correct in assuming that I should not have to do any explicit handling of data changes the user makes (via client side script and manipulation of an Data Structure Representing the Repeater Data); and the View State should maintain the data I need to access on the server when submitted?
I do not believe that it is the User Control visible state changes that are causing the issue because when the page is initially loaded on of the User controls is populated with dummy rows (so it displays).
I am suspicious that because the visible state of the controls is changed during partial page post back, that the Page View State ends up with no knowledge of the User Control and therefore cannot track its data (or changes).
I need to process surveys. I have modelled them in SQLServer, just need to generate the forms to input it.I have nested SqlDataSource/DataLists. The outer gets the questions and the inner gets the various options as a plain HTML radio buttons. I can't use ASP.NET radio buttons because of a bug with them inside itemtemplates not mutually exclusive http://support.microsoft.com/default.aspx?scid=kb;en-us;316495Anyway, so now I need to know the which radio buttons were selected so I can insert the values in the database. What is the best way of doing it?

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 want to create a trigger for insert and whenever i insert the data the trigger should fire and notify some value inserted i want to create log table to save this information,now i have created a trigger but i dont know how to map it to log table to notify the changes?

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've seen a good few questions like this around but havnt actually come across any articles with the answer (maybe just been unlucky with my research!).
Basically I'm looking to have say 3 links (or buttons) on a page, which in turn will dynamically load a specific user control into an update panel with AJAX.
Then I would like the usercontrol loaded to be capable of handling postback within the update panel (basically no page refreshes) to do its processing and return output.
Does anyone have any pointers to articles/blogs covering this?
I've seen many but non covered handling postbacks from the user control or handling the postbacks within the update panel.
