Events Overview
The RadImageButton exposes several client-side events that allow easy and flexible use in a wide range of application scenarios:
-
OnClientLoad (load) - raised when the control is initialized.
-
OnClientClicking (clicking) - raised when the user clicks the button. The event can be canceled.
-
OnClientClicked (clicked) - raised when the button is clicked. The event is subsequent to the OnClientClicking event.
-
OnClientMouseOver (mouseOver) - raised when the mouse hovers over the control.
-
OnClientMouseOut (mouseOut) - raised when the mouse leaves the control.
To handle the desired event, the user must set the respective property to the name of the JavaScript function handling the event or to an anonymous JavaScript function. Here is an example:
Example 1: Passing named (non-anonymous) JavaScript function.
<script type="text/javascript">
function Click(sender, args)
{
alert("RadImageButton was clicked.");
}
</script>
<telerik:RadImageButton ID="RadImageButton1" runat="server" OnClientClicked="Click">
</telerik:RadImageButton>RadImageButton1.OnClientClicked = "Click"; //passing the name of the JS functionExample 2: Passing an anonymous JavaScript function.
<script type="text/javascript">
function Click(button, args, arg1, arg2)
{
alert("arg1:" + arg1 + " arg2:" + arg2);
}
</script>
<telerik:RadImageButton ID="RadImageButton1" runat="server" OnClientClicked="function(sender,args){Click(sender, args, 'Value1', 'Value2');}">
</telerik:RadImageButton>RadImageButton1.OnClientClicked = "function(sender,args){Click(sender, args, 'Value1', 'Value2');}"; //passing the name of the JS function
