Use List<> to store your employee and implement the following -
Distinct(IEqualityComparer<(Of <(T>)>))
You can use your own implementation of IEqualityComparer[^].

protected void btnupload_Click(object sender, EventArgs e)
{
String savePath = Server.MapPath(@"your path\\");
if (FileUpload1.HasFile)
{
String fileName = FileUpload1.FileName;
savePath += fileName;
FileUpload1.SaveAs(savePath);

Hi all
I have a grid view which is used to delete the data in it. I want the data to be stored in another table before it is deleted from the actual table. The database is in Oracle. I am using the following code.
Sub GridView1_RowDeleting(ByVal sender As Object, ByVal e As GridViewDeleteEventArgs) Handles GridView1.RowDeleting
Dim oradb As String = "Data Source=(DESCRIPTION=" _
+ "(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=Mahasilbkp.ltuisb.net)(PORT=1521)))" _
+ "(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=db21a)));" _
+ "User Id=<userid>;Password=<password>;pooling=false;enlist=false;"
Dim conn1 As New OracleConnection(oradb)
conn1.Open()
Dim cmd1 As New OracleCommand
cmd1.Connection = conn1
GridView1.DataBind()
cmd1.CommandText = "insert into uu.record_backup(ntn, name, status, enf, aud, sector, delete_user) select ntn, name, status, enf, aud, sector" + ",'" + Label5.Text + "'" + " " + "from uu.total_cases where trim(ntn)=" + "'" + GridView1.SelectedValue + "'"
Dim dr1 As OracleDataReader = cmd1.ExecuteReader()
dr1.Read()
dr1.Dispose()
dr1.Close()
cmd1.Dispose()
conn1.Dispose()
conn1.Close()
End Sub
The insert command execute perfectly if I remove the GridView1.SelectedValue. But it does not give the desired result as I want the value displayed in the data grid to be inserted only, before it is deleted. What happens in the above code is that data is deleted from the actual table, but nothing is inserted in the backup table described in the code above. I understand I need to write something else instead of GridView1.SelectedValue, but I can't think of anything else. Please help me with this.
Thanks.

I think there may be some mistake in your query. Please refer Trigger concept to implement your desired results.

If there's mistake in query then how come it runs when i remove the GridView1.SelectedValue from it. I just need to get the value of the first column in the grid view. For that I need help. Thanks.

protected void grid_category_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
clsclass comfun = new clsclass(); // your main class or
sqlcommand cmd;
Label val = (Label)(your_grid.Rows[e.RowIndex].FindControl("lbl_id"));
comfun.ExecuteNonQuery("delete from evaluation_category where
evaluation_category_id=" + val.Text);
Label val1 = (Label)(your_grid.Rows[e.RowIndex].FindControl("lbl_1"));
Label val2 = (Label)(your_grid.Rows[e.RowIndex].FindControl("lbl_2"));
Label val2 = (Label)(your_grid.Rows[e.RowIndex].FindControl("lbl_3"));
cmd.executeNonQuery("insert into table values('"+ val1.text +','' + val2.text
+'',''+ val3.text+'")
// or done this query in storedprocedure
// or both query can be done in same procedure
// first remove value from first table then send thia to next one simple
FillGrid(); // bind your grid
}
Try this.

I tried your code and it's giving the following error
Object reference not set to an instance of an object.
It's coming in the line where I am using "val.text" in the insert statement.

I would like to say one thing, make sure to put all insert statement in signle transaction.
It is mean firt do the Bigin Transaction
Update/Insert first table
......
Commit transaction
If anywhere exception occured then do the Rollback transaction.
Note: Insert or Update query you can find on google.

ASP.Net does not provide any way to do this.
And I am sure that this is not that easy to implement on your own untill and unless you have a ready component available which youn can directly use.

Hi everyone! I have a sitemap.xml that contains my links to the various sub pages. What I would like to do is have the system change the color of some of the titles so they stick out when new content is released. I've tried simply adding <code><span style="font-color:red">(new!)</span></code> in the xml file but that always bombs out. Can this be done? The only other way I could think of pulling it off would be dynamically checking all of the sitemap nodes for "(new!)" somewhere in the title and then adding the span block while the page is loading.
Thanks!

If anyone runs into this, I figured out how to pull it off using the ItemDataBound event.
protected void Menu1_MenuItemDataBound(object sender, MenuEventArgs e)
{
if (e.Item.Text.Contains("(NEW!)"))
{
e.Item.Text = e.Item.Text.Replace("(NEW!)","<span style=\"color:red\">(NEW!)</span>");
}
}
