View 1 RepliesPage Post Back But Server Click Event Doesn't Fire
Aug 31, 2010I 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.

View 5 RepliesC# - Using A Timer Post Back, Which Controller To Use That Doesn't Post Back To Server?
Jul 14, 2010Being 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.

Update Javascript After Async Post Back In C#?
Feb 4, 2011I 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.

How To Send Text Message Using JavaScript To Avoid Post Back
May 25, 2010This 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;" />
<div id="id1" runat="server" style="visibility: hidden; background-color:Green; width:100%; height:100%">
<asp:TextBox ID="TextBox1" runat="server"
AutoCompleteType="Disabled" Rows="3"
TextMode="MultiLine" Width="98%">
</asp:TextBox>
<asp:Button ID="Button2" runat="server"
Text="Post"
onclick="Button2_Click" />
<asp:Button ID="Button3" runat="server"
Text="Cancel"
OnClientClick="visibleDiv('id1'); return false;" />
</div>

Web Form And Ajax Data Lost On Post Back - Finding Possible Cause / Ajax Or Changing Visible Property
Sep 15, 2010I 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).

View 1 RepliesAJAX :: How To Do Update Panel And Dynamic Controls And Post Back
Sep 29, 2010 I have a page that is mostly dynamically built in the page load of my VB.net code behind page.
The issue is that I made a change to the page and added a button that redirects to a secondary page. When the button is clicked there is a very noticeable lag until the button click event fires because the page is being rebuilt every time.
I had not wrapped the code in the load event in the If not ispostback.... because I have dynamic controls that the user interacts with and I need the page to be rebuilt when the user clicks them.
The dynamic controls are clickable table cells. I did some looking and I found that the RegisterPostBackControl. I thought this would be perfect but, it does not although I maybe using it incorrectly.
Here is the code flow.
