尝试写作dtp.acceptChanges();
看看是否有效。

for(int i = dtP .Rows.Count-1; i> = 0; i--)
{
DataRow dr = dtP.Rows [i];
if(dr [name] ==Joe)
dr.Delete();
}希望这是你要找的..
for(int i = dtP.Rows.Count-1; i> = 0; i--)
{
if(dtP.Rows [i] [Col_Name])=Value)
{
dtP.Rows [i] .delete();
}
})
I have 2 grid views in a page like gridview2 and gridview3, when user click on gridview3 I fetch the data and filled in gridview2 depend on unique number from gridview3 after that user can delete the data and add data in gridview2 (not from database) , I written code it's deleting data from gridview2 but row was not removing (empty row showing)
thanks
What I have tried:
stored the data in dtp datatable
in GridView3_SelectedIndexChanged
{
Session["rdt"] = dtp;
GridView2.DataSource = Session["rdt"];
GridView2.DataBind();
}
---------------------------
in GridView2_RowDeleting
int index = Convert.ToInt32(e.RowIndex);
DataTable dt = (DataTable)Session["rdt"] as DataTable;
dt.Rows[index].Delete();
Session["rdt"] = dt;
GridView2.DataSource = dt;
GridView2.DataBind();
Try writing dtp.acceptChanges();
See if this works.
Please mark this as answered if this solves your problem.
for(int i = dtP.Rows.Count-1; i >= 0; i--) { DataRow dr = dtP.Rows[i]; if (dr["name"] == "Joe") dr.Delete(); }Hope this is what you are looking for..
for(int i = dtP.Rows.Count-1; i >= 0; i--)
{
if(dtP.Rows[i]["Col_Name"])="Value")
{
dtP.Rows[i].delete();
}
