C# - OnClick Event For ImageMap Never Being Invoked?
Jun 4, 2010
I have an ImageMap control in an ascx file of mine. I'm trying to make something happen when the user clicks on an area in the map, but the page just posts back without my "imageMap_Click" event handler never being invoked.
I have an imagemap with 3 hotspots. One downloads a .pdf, the other two redirect to two other websites. Now they want to be able to track who downloads the .pdf file with our reporting program (VisiStat). To do that, I have to add some code to the OnClick event of the .pdf hotspot.
[Code]....
The code in the "VSLT('MyFile.pdf')" can be any name, that's what shows up in the reports.
I've tried doing this with a code behind OnClick event handler, but it can't see the javascript included in the asp page:
[Code]....
And I'm guessing that's where the VSLT code is at. I tried moving my code inline in the asp page, but it always says my sub is not a member of the page. What am I doing wrong? It seems like I'm just calling it or referencing it wrong.
How do I setup a default setting so that if I do not set an OnClick (i.e the asp.net OnClick attribute) explicitly for an asp:LinkButton tag, it will not render an onclick(html attribute for javascript) attribute client side? By default, asp.net adds an onclick='doPostBack....' for the LinkButton.
Case for use:
There is a LinkButton tag on the page. For this page, if the user has one friend, I only want to run client side code if the button is clicked and would not for any reason want to make a post back. If the user has more than one friend I would want a click to trigger a postback.
Using any asp.net Ajaxtoolkit
Dynamically switching the control type (i.e. if friends == 1 use a asp:Hyperlink)
-I want to avoid this because it is not scalable. There might be many cases where I want an asp:Link tag to do a postback or to not do a postback depending on the user context or user attributes Using OnClientClick (I am using jQuery would like to avoid this)
well i have already created the rows and cells dynamically using asp.net table control ...but how to add an onclick event on that ...so that i could retrieve the corresponding cell when a particular row is clicked ...if it was a html control ,i could have used javascript but in this particular case m unable to find any solution..
In my View, there is a HTML button; I would like to execute a function from Controller when user clicks on that button. I need to pass a value from HTML textbox as parameters. My function will do some calculating and return the result back to the same View.
Let's make a simple example.
I would like to input "1" in my textbox, press the button, pass "1" to controller, and in the function, I will do something like 1+1. At the end, I will pass the result, which is "2" back to the View.
have a user control that has a data repeater. When the ItemDataBound even is raised I create a html table which contains a button on each row. The button is created in a seperate class, not in the code behind, so when I attach the button click event I have to put the click method in the class that creates the control. However, when the button is clicked I need to open a modal form in the page that contains the button. How can I move the event back to the web user control with the sender object? I suspect I need to do something with a delegate or something, but I am having a hard time putting how to do that together. Can someone tell me how to do this?
I am having a treeview with nodes of products populated on first time through xmlresponse.Onselectednodechanged event, I have performed xmlseriaization to build a request to get list of subproducts. Now, my issue is how do I handle the next On_click event requesting for items under subproducts which will inturn calls the same onselectednodechanged method and how do I write condition to skip above steps to occur, since I need to build a different request on click of subproducts asking for items.
I am trying to define an event on a listbox to allow users to click on a specific item and do processing on the event. I've tried the obvious OnClick and OnSelectedIndexChange events which are not part of the listbox collection of events.
I have an XML file that contains a list of training videos that our site offers. I'm using a DevExpress control called DataView and within the ItemTemplate I bind all the appropriate information. However, I have an ImageButton that I bind a downloadVideo(string fileName) function to the OnClick event. When I click on the image the function does not fire though. Can anyone see what I'm doing wrong?

When I view the source of the page the OnClick event reads OnClick=downloadVideo(fileName.mp4) .
what i have is a form and when i click on a icon then in javascript it pops up a window with data bound to a grid. Now on that form if i hit tab in a particular text box how can i call that same window ( ie just call the javascript onclick event and pass the text in the text box) ?
Void button has a confirm box after receiving true, expecting running another button's click event however, Void2_Button_Click not run, where is wrong?
protected void Void2_Button_Click(object sender, EventArgs e) { // do something } Void_Button.Attributes.Add("onclick", "var agree=confirm('Confirm to void?'); if (agree){document.getElementById('Void2_Button').click();}");
I've double checked the if class name & code file in aspx and aspx.cs files match(and they do). Removing the OnClick part of the button declaration in aspx file (or changing it to ie. OnClick="Page_Load").What might be the reason for this? Do I have to register my functions somewhere?
I would like to add an Onclick event to one button (ShipEdit is the name of the button), I would like to redirect user by clicking this button to new page that is (../Account/MyAccount.aspx) and send 2 variables that is (LineItem.LineKey and shipment.ShipmentKey) with the URL: I need to write a code in this module:
Have a form with a button and some text fields on it.When I hit enter after filling a field the event for the button fires up event onClick.How can I get around this since on one of the fields I have a textchangeEvent I to fire up.
I have the following code and no matter what I do onclick event for button is not firing. I tried deleting the button, the pages. Redid the code. Moved the web project to a different computer and nothing. It worked a few hours ago.
I have an imagebutton with an postbackurl and an onclientclick script. When i added the onclientclick code, if my javascript validation passes (aka returns true), the page just seems to perform a postback (the screen just seems to refresh
I decided to change what JS functions Im calling now since calling Multiple functions definately wasnt helping. Here's my updated code. All Im doing now is validating a single textbox and returning true or false. Even this simple function is causing the postback URL to never get called. Could it have anything to do with the fact that Im trying to call a function to return a true or false?
Who knows how to add onClick event to accordion pane in Ajax asp accordion ? Is it the same as adding it as attribute in server side or there is another way in client side?
The intent is that when the LinkButton is clicked, it disables itself and returns false to prevent the postback (this control is used as a trigger for an animation).
What I'm trying to accomplish is to set my dynamically created linkbutton with a onClick command so when click it will run a method in the code behind. This is my code:
ive imagebuttons which created in runtime from database and i need to add them onclick or mouseover event but i failed imagebutton.click += new ImageClickEventHandler(imageButton_Click); im adding this when i created imagebuttons, what i need else also i tried javascript but its not firing too;
