I wanted to post back after an auto complete extender did its job. This was the first version (the auto complete extender showed student names).
Server-side:
protected override void OnPreRender(EventArgs e)
{
base.OnPreRender(e);
if (!Page.ClientScript.IsClientScriptBlockRegistered("postBackStudentFound"))
{
Page.ClientScript.RegisterClientScriptBlock(this.Page.GetType(), "postBackStudentFound",
@"<script type=""text/javascript"">function postBackStudentFound() {" +
Page.ClientScript.GetPostBackEventReference(this.Page, StudentFoundEventArg) + "; } </script>");
}
if (Page.IsPostBack)
{
if (Request["__EVENTARGUMENT"] == StudentFoundEventArg)
{
OnStudentFound();
}
}
}
Client-side:
<script type="text/javascript">
function itemSelected( source, eventArgs)
{
var fullString = eventArgs.get_value();
var valuesArray = fullString.split("|");
var id = valuesArray[0];
var key = valuesArray[2];
$get('<%= txtID.ClientID %>').value = id;
postBackStudentFound();
}
</script>
