I add the following functionaility to the checkbox within the InitialIzeRow handler

protected void webdgRequest_InitializeRow(object sender, Infragistics.Web.UI.GridControls.RowEventArgs e)

{

string Id = ((Label)e.Row.Items[0].FindControl("lblID")).Text;

var chkBox = (CheckBox)e.Row.Items[1].FindControl("chkDeleted");

if (chkBox != null && Id != null)

chkBox.Attributes.Add("onClick", "return getClickedRow(" + Id + ",'" + chkBox.ClientID + "');");

}

Which in turn calls the following Javascript each time the check box state is changed:

<script type="text/javascript">

function getObj(name) {

if (document.getElementById) // test if browser supports document.getElementById

{

this.obj = document.getElementById(name);

this.style = document.getElementById(name).style;

}

else if (document.all) // test if browser supports document.all

{

this.obj = document.all[name];

this.style = document.all[name].style;

}

else if (document.layers) // test if browser supports document.layers

{

this.obj = document.layers[name];

this.style = document.layers[name].style;

}

function getClickedRow(rowClicked, checkBoxID) {

var params;

var clientSideCheckBoxID = new getObj(checkBoxID);

if (clientSideCheckBoxID.obj.checked == true) {

params = rowClicked + '-' + 'checked'; // We can split this string on the server side to determine how we need to update the data source

__doPostBack('<%= webdgRequest.ClientID %>', params);

} else {

params = rowClicked + '-' + 'unchecked'; // We can split this string on the server side to determine how we need to update the data source

__doPostBack('<%= webdgRequest.ClientID %>', params);

}

</script>

However when I try to do the post back, I keep getting PageRequestManagerServerErrorException.

What could be causing this?

Kind Regards
