Jun 7, 2010

i have asp button like this:

<asp:Button ID="ImportToDB" runat="server" OnClick="ImportToDB_Click" />

And i need to call a javascript function when mouseover on this button. So i have in page_load():

ImportToDB.Attributes.Add("onmouseover","javascript:OnButtonMove(" + ImportToDB.ClientID + ")");

javascript function:

<script language="JavaScript" type="text/javascript">
function OnButtonMove(id) {
//something
}
</script>

Everithing work fine only if button is enabled. but when i disable button, this javascript function will never fire.

Jan 7, 2010

I am trying to run a routine that (when a button is clicked) changes an asp:label's text to "Please Wait..." using Javascript, and then goes away and runs a c# function that changes the asp:label's text to "Finished" when it is complete.I can get the Javascript to work:

<asp:Button ID="Button1" runat="server" Text="Upload"
onclientclick="document.getElementById('errorMessage').innerText='Please Wait...';" />

And I can run the c# bit fine too:

<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />

Registerclientscriptblock - Call A Javascript Function At The End Of Button Click Code Behind?

Oct 8, 2010

My motto is to call a Java script function at the end of button click code behind. ie, firstly i need to execute the server side function after which my java script function should get invoked. My server side method is as follows

protected string SaveEmbedURL_click()
{
if (txtembedurl.Text != null)
{
School aschool = new School();
aschool.SchoolId = CurrentSchool.SchoolId;
aschool.EmbedUrl = txtembedurl.Text;
SchoolRespository.updateEmbedUrl(aschool);
return "true";
}
}
My Java script function is as follows
function SaveEmbedUrlClientSide() {
admin_CustomizeTheme.SaveEmbedURL_click(true);
$('#lbl_embedcode').removeClass('hide').addClass('show');
$('#embedCode').removeClass('hide').addClass('show');
CopyToClipboard("embedCode");
}

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?
