Server side button calling JavaScript function Messages   Related Types This message was discovered on ASPFriends.com 'aspngclient' list. Greg Quinn I have the following web control... <asp:button id = "shareBut" Text = "Sharing..." onClick = "JavaScript:Initialize();" runat = "server" /> Since it is a server control, obviously the JavaScript is not recognised as a .NET function. Now besided writing my own function that response.writes the Javascript, is there any quicker way to call a JavaScript function directly from a web control? Greg Reply to this message...        Andy Smith if you want to attach clientside handlers to the final rendering of the = control, then you can usually add them to the attributes collection of = the control like thus: [C#] myControl.Attributes["onclick"] =3D "myJavaScriptFunction();"; there is not, however, any way to add this specific handler in the tag = of the control, because it would interfere with the serverside onclick = attribute. __ Andy Smith Keyboard Jockey #3a7-2.78.1 [Original message clipped] Reply to this message...        babu n (Type your message here) -------------------------------- From: babu n Reply to this message...        Greg Quinn Okay thanks, but the problem with that approach then is that the form the button resides in still refreshes when the button is clicked. I need a button that when clicked only calls my Javascript, it mustn't refresh the form again. But I also need it to be running server side so I can set it to visible or invisible based on certain conditions.
