Add Onclick Or Mouseover Event To Imagebutton At Runtime?
Feb 1, 2011
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;
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?
i have a navigation bar made up of ImageButtons that have their image swapped out on mouse over and back on mouse out. i used this code in the Page_Load handler to do this:
and I want when I click on linkbutton it doesn't open new window...
here when I click on linkbutton it doesn't open new window it is correct but when I click on imagebutton and it opens new window and back to page and click on linkbutton it open linkbutton in new window...
I want when I click on link button it doesn't open new window any way...
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..
on the code page I have mapped the OnCommand event to the following code
Code:
Protected Sub ImageButton_Command(ByVal sender As Object, _ ByVal e As System.Web.UI.WebControls.CommandEventArgs) Try Dim img As ImageButton = CType(sender, ImageButton) img.BorderStyle = BorderStyle.Ridge SortOrder = e.CommandArgument BindData() Catch exc As Exception ProcessModuleLoadException(Me, exc) End Try End Sub
My problem is that by clicking on the image button in the gridview header, the OnCommand event is not being fired. I have tried this with both OnClick and OnCommand and neither fires. I can't see what I am doing wrong if anything.
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)
I have image button in my page i set an image for this control i want when mouse go over on my imagebutton my imagebutton picture change how i can do it?
I have a simple web page which contains an ImageButton. I wanted to know that is there any way for me to change the ImageSource of this ImageButton while the Mouse is over the element.
I used to change it as follows:
OnMouseOver="src='image/image.gif';"
I want this image to change through a duration.
for example, if you want to change a background image, you use:
How to change visibilty of panel based on imagebutton mouseover and mouseout here, i have panel1(Panel) and btnimg2(imagebutton) i want to show(Panel1.visibility=true) when mouseover happens on imagebutton and Panel1.visibility=false when mouseout on imagebutton
I created an image button called "pic1" with the OnClick feature. When clicked it runs "btnClicked". In the sub "btnClick", how would I get information? One example is to get the button tooltip. I tried this: request.form.item("pic1.tooltip"). That did not work.
Why isn't the image displayed? The folder images is in the same folder as the .aspx file.Why doesn't it invoke the ImageButton1_Click method when I click on the image? The OnClick should be for the server side.The ImageButton1_Click method takes 2 parameters, but why OnClick does not require 2 parameters?
The 2 parameters are: object sender, ImageClickEventArgs e. What are they and why I pass in a string and a gridview, which I don't think match with the arguments definition, and it still works?
If I use an ImageButton or LinkButton, I just noticed that when clicking either, the Page_Load method executes before the method specified in the OnClick. Can this be avoided so that the method in the OnClick is triggered instead of Page_Load?
I have a requirement whereby one or more image buttons need to be created in a user control at runtime. The number of buttons is determined from a database where a user can add one or more rows that contain an image for each button, so if a user adds 3 images to a table, 3 image buttons are created. Ive used this code but I get an error at runtime
The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases.

this is the usercontrol aspx

I basically want one or more buttons to render within the div in the usercontrol. Ive only got the code written for one button at the moment while I test the rendering, eventually they will be rendered in a loop of records taken from a database. Whats the best way to do this ?
How do you get an invisible button in a Gridview templatefield (button1) to become visible when the mouse is over the panel it's within (panel1) and then disappear once again when the mouse has been moved out of the panel. Also, how do I change the panel's background color depending on whether the mouse is over it or not? By the way, I'm trying to get the panel to change color and the button to be exposed ONLY for the record pointed to and not for all the records.Below is a simplified version of my Gridview.
Is it possible to show an event when I mouse over on a specific event? The calendar's events come from a database and the date's backcolor is different if it has a scheduled event.
I have a asp calender control on page.When i hover on perticular date, if the event is registerd then it should show me a popup with event details. The event details are fetched through database.
yes client side must be java script but my qustion is not that.i am asking that can i use c# language to implement "actions" fired on "click side events" such as mouse over the reason for this question is that i remember some syntax of registering functions for particular events of formview, which are call when the event occurs (yes there ispostback involved" is something like the above possible for client side events using c# or even vb.net
protected void Page_Load(object sender, EventArgs e) { Label3.Text = "this is label three"; Label3.Attributes.Add("OnMouseOver", "testmouseover()"); } protected void testmouseover() { Label4.Text = "this is label 4 mouse is working!!"; }
