Hi,

I have this code it inserts a new row into my datagrid visually
thats working but when i go to update it nothing is happening!!

if(EvolusysKokugo.CurrentKokugo() == "En")
{
    DataSet ds = ((DataSet)Session["NewData"]);
    DataTable dt = ds.Tables["ControlData"];
    DataRow dr = dt.NewRow();
    dt.Rows.Add(dr);

    Session["NewData"] = ds;
}
else
{
    DataSet ds1 = ((DataSet)Session["NewDataLang"]);
    DataTable dt1 = ds1.Tables["ControlLanguageData"];
    DataRow dr1 = dt1.NewRow();
    dt1.Rows.Add(dr1);

    Session["NewDataLang"] = ds1;
}
    int nNewItemIndex = EvolusysGrid.Items.Count;
    if(nNewItemIndex >= EvolusysGrid.PageSize)
    {
        EvolusysGrid.CurrentPageIndex++;
        nNewItemIndex = 0;
    }
    EvolusysGrid.EditItemIndex = nNewItemIndex;
    this.BindData();

Is there something wrong with this???
Thanks Dean

I think that with the this line:
DataTable dt = ds.Tables["ControlData"];
you only make a copy of the table that is inside your dataset, not a
reference (I didn't check this) so if you change the copy (dt) and than
update your session with the original your changes are not being applied.

So try something similar (not tested):

DataSet ds = ((DataSet)Session["NewData"]);
DataRow dr = ds.Tables["ControlData"].NewRow();
ds.Tables["ControlData"].Rows.Add(dr);
Session["NewData"] = ds;

hth,
