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 developed a web application which contains aspdotnet treeview control. In this treeview control has binded with some database value.. that controls has one parent node and more than one child nodes for each parent node.
my problem is here, when the user clicks the parent node, I need to fire a javascript onclick function before the server side event(SelectedNodeChanged) called..
If I provide javascript to the parnet node when it is binding, then I could not fire the server side event(SelectedNodeChanged).
How to provide onclick javascript event for parent node in treeview control even the parent node has SelectedNodeChanged event.
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?
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).
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.
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:
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) scn.DeleteIteration() Response.Redirect("Calibration.aspx") 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) scn.DeleteIteration()
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.
i got this requirement to do using vb.net. there is a page on server which is html with borders,text and tables. i have to convert it to pdf onclick of button. this is not asp.net but vb.net.
<asp:RadioButton GroupName="grpAssoc" ID="rbtEvery" runat="server" Text="Everyone" onclick="return doChangeAssociationType(0);" AutoPostBack="True" oncheckedchanged="rbtEvery_CheckedChanged" /> but oncheckedchanged="rbtEvery_CheckedChanged" not firing even javascript function returns true
I am using Ajax authentication service to login/logout users.And have 2 boxes one for logged users,another for any user.When user logged in he get loged in box,then go to another page,then press back,i have unlogged box.In Page_Load i check if (Reques.IsAuthenticated) then i change box on corresponding,in this case on Logged in box.But Page_Load is not called when i press button back(in browser) or backspace.
I have a web page which has both asp.net controls as well as AJAX controls.I am facing a weird issue when I introduce some AJAX controls(Modal popup) inside a tabbed panel, the button onClick event stops firing.
I have a modalpopup extender attached to a button. That is to say the button is the targetcontrol id of the modalpopupsxtender. I would still like the onclick event of that button to work because only the onclient click event is working. How can i go about this.
I want to show model popup, I have One asp page in that Collapsible Panel and tow user control and one button, Suppose I click on button then show the model popup and hide the panel and user controls..
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?
