Javascript and server calls

[Ric Pullen]

Is it possible to have a button run client side script and then depending
if its valid allow the postback to continue otherwise it prompts the user.

I know this sounds like a validation issue but its not possible to do it
with the validation components.

I use infragistics webgrid and i want to test if there is an active row...
if so then I will allow a postback otherwise prompt the user to select one.

I have already assigned the javascript with the following code
btnEdit.Attributes.Add("onclick", "javascript:EditRowSelectedCheck()")

Cheers.

1)There is much better place to ask questions related to infragistics:
[url]http://www.infragistics.com/support/newsgroups.asp[/url].
2)

function IsSelected(){
var grid = igtbl_getGridById(GridId);
return (grid.getActiveRow() != undefined);
}

GridId here string(Id of UltraWebGrid)
