AJAX :: Change The Onclick Function Called By An HTML Button?

Feb 3, 2010

I am writing my first AJAX enabled page. Basically I am trying to expand out the lines of a Purchase Order (PO) using our company database. What I want to do is have a button that will that will call on a javascript to update a div field with a table for the PO lines of that PO and at the same time change the function that is called by the button to a function that will collapse the list. How would i do this?

I have tried the line in javascript:

document.getElementById('Button ID').onclick=CollapsePOLines(POID)

However it doesnt seem to change the onclick event for that button, it doesnt throw an error though.

Button Click Doesn't Call Function Even When Button Attribute OnClick Is Set To That Function

Mar 19, 2010

I have an aspx page with two buttons, one of the buttons has an OnClick attribute to a function that should be run when clicked. When the other button is clicked there is an if statement checking if the page is a postback, if it is then I run some statements that need to be run when that button is clicked. That postback button works fine. However, the other button, when it's clicked the function it's supposed to call never executes, and the statements inside if (Page.IsPostBack) get executed instead. What can I do to fix this? Is there a way to make the button that calls a function not do a Post back?

Web Forms :: Onclick Called Twice - Getting Error - "one Function"

Mar 20, 2011

I have a problem with the onclick button requests in ASP, my button is:

<asp:Button ID="btnLogin" runat="server" onclick="btnLogin_Click" onclick="clicked()" Text="Login" />

I need the onclick to be called twice, once for JS client side validation and once for C# serverside validation, when I try this function I got the error saying that only one onclick function maybe called. Does anyone know how I would go around checking both client and server side validation with one click? I've got no idea where to start and the search engines are only returning one of each (either server or client).

Sep 10, 2010

Obviously I am a total noob and this is simple to some of you, but I can not figure out why the rest of the sub works, but the button1.Text="Uploading, Please Wait..." seems to be completely ignored.

The button is supposed to change text when clicked but no method I have tried works with my page.

Here is my simple upload form page:

AJAX :: Getting A Function To Run On OK When ModalPopupExtender Is Called?

Jan 18, 2011

I'm having some trouble getting this to work. basically I got the modalpopup to show, and when it's shown i have 2 buttons (Yes and Cancel). When yes is clicked i want a function to be called. Here is my asp.net code:


<asp:Button ID="btnMpeDummy" runat="server" Text="Test" style="display:none" />
<ajaxtk:ConfirmButtonExtender ID="cbeDelScn" runat="server" TargetControlID="btnMpeDummy" DisplayModalPopupID="mpeDelScn" />
<ajaxtk:ModalPopupExtender ID="mpeDelScn" runat="server" TargetControlID="btnMpeDummy" PopupControlID="pnlDelScn" OkControlID="btnDelScnYes" CancelControlID="btnDelScnCancel" BackgroundCssClass="modalBackground" />
<asp:Panel ID="pnlDelScn" runat="server" CssClass="modalDialog" style="display:none; width:300px;">
<asp:UpdatePanel ID="upnl3" runat="server" ><ContentTemplate >
<asp:Label ID="lblDelScn" runat="server" Text="Delete Iteration" />
</ContentTemplate></asp:UpdatePanel><br /><br />
<asp:Button ID="btnDelScnYes" runat="server"
<asp:Button ID="btnDelScnCancel" runat="server"
ToolTip="No" />


And here is my VB code:

Protected Sub btnDelScnYes_Click(ByVal sender As Object, ByVal e As UI.UIIterationList.IterationListEventArgs) Handles btnDelScnYes.Click
Dim scn As dat.Iteration = New dat.Iteration(e.iterationID, SessUserID)
End Sub

Not sure if this is useful, but just some info: My page have a list of iterations. there are several columns to this table. when the last column is clicked, the modal popup shows and asks the user if to confirm if he/she wants to delete this iteration which is this code:

Dim scn As dat.Iteration = New dat.Iteration(e.iterationID, SessUserID)

so i'm trying to get the funtion to be called, but it's not working. when you click "OK" nothing happens. when i debug it and trace the logic it doesn't even go into the above VB subroutine.

C# - HTML Button's OnClick Property Inside (.cs)

Jul 2, 2010

I just wanna find out if there's a way to put my onClick event inside .cs:

<button type="submit" runat="server" id="btnLogin" class="button" onclick="btnLogin_Click();">

where Login_Click() should be inside .cs:

protected void btnLogin_Click(object sender, EventArgs e)
// do something

I will not use ASP.NET button here, and that I will not put my Login_Click() event inside .html/.aspx so I can't 'expose' my codes.

Link Button And JavaScript / Change A Standard HTML Input Button To A Link Button

Mar 1, 2011

I need to change a standard HTML Input button to a Link button but am running into problems because the existing

code calls a javascript function. The function basically does the same as the browser back button. When I add the code and

set the property runat="server" I get a "CS1026: ) expected".

Quite new to ASP,net (VS2010) so could be going about this the wrong way.

Executing Only The Last Function Called?

Feb 22, 2010

This is the setup in short. I have a big table. Everytime a cell get focus an asyncron call to the server is done (with PageMethods) and some data is returned and updates a infobox in the page.I have written code that makes it possible to navigate between cells with the arrow keyes.

The problem occurs when I shift focus fast through several cells in order to get to the cell I want. Every get-focus is executed and since the communication with the server takes about half a second it get quite irritating and not very user friendly.Ideally I would like to execute only the last focus event. But how? I cant know which event is the last one, can I?
