ok i got very big issue on this.

i have this code server side:

protected void grdFlowDetails_DeleteRow(object sender, ISNet.WebUI.WebGrid.RowEventArgs e)
{
if (e.Row.Type == RowType.Record)
{
if (e.Row.Table.DataMember == "parent")
{
DataRow row = e.Row.GetDataRow();
int intTemp = Convert.ToInt32(row["AppealFlowLineID"]);
Flows.Instance.DeleteFlowDetails(intTemp);
}
}
}

and the client side is this:

_openFormWindow: function (type) {
var based = this;
var url = "";
var isRootTable = true;
var selObj = based.gridObj.GetSelectedObject();
if (selObj != null && selObj.Table != undefined) {
isRootTable = selObj.Table.IsRootTable;
}
switch (type) {
case based.Config.CommandIssueActionAdd:
if (isRootTable) {
UtillObject.SetDialogBox(based.dialogObj, based.Config.Lang.AddNewFlowDetailForm);
based.dialogObj.SetContentURL(based.Config.UrlFlowDetailFormAdd);
based.dialogObj.ShowDialog();
}
break;

case based.Config.CommandIssueActionEdit:
if (isRootTable) {
UtillObject.SetDialogBox(based.dialogObj, based.Config.Lang.EditFlowDetailForm);
if (selObj != null) {
var row = selObj.GetRowObject();
var cells = row.GetCells();
var id = cells.GetNamedItem("AppealFlowLineID").Text;
if (id == null) {
alert(based.Config.Lang.FlowNotSelected);
return false;
}
based.dialogObj.SetContentURL(UtillObject.StringFormat(based.Config.UrlFlowDetailFormEdit, id));
based.dialogObj.ShowDialog();
}
else {
alert(based.Config.Lang.FlowNotSelected);
return false;
}
}
break;

case based.Config.CommandIssueActionDelete:
if (selObj != null) {
if (confirm(based.Config.Lang.AreYouSureDeleteItem)) {
based.gridObj.GetSelectedObject().GetRowObject().Delete();
}
}
else {
alert(based.Config.Lang.FlowNotSelected);
return false;
}
break;
}
}

and asp.net is this:
