VS 2010 : Combine Similar Rows In A Datatable (the Rows Only Differ By One Column)?

May 8, 2012

I have three sub tables that I want to process. For each I want to combine the rows, as they are only different by contents in the second column(I want to do the same to the fourth column, later):

'Sub table 1
xx|C201 |02300877 |Samsung |....
xx|C201 |02300877 |Toshiba |....
xx|C213 |02300877 |Samsung

[code]....

p.s. For the fourth column, Manufacturer information , I want to do the same and I'd probably get something like this for the final table:

xx| C201,C213,C606,C619 |02300877 | Samsung
xx| C201,C213,C606,C619 |02300877 | Toshiba
xx| C303, C305,C712 |02301163
xx| C207, C209, C708 |02301165

VS 2008 (DataGridView) :: Delete Successful Inserts Of Rows And Move Rows Up?

Jul 30, 2010

How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.

Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click

How To Add New Rows Into DataTable

Feb 15, 2012

I have a form with a textbox and a add button. User can write a name down on the textbox and click add button. it will save in a datatable with auto ID. After that, the textbox is cleared and the user can write another name on the text box and click the button. This should add to the existing datatable on memory with existing ID + 1. Show on the gridview. (this is just for display purpose to confirm it works)

I have a datatable like this.
Button1.click() event
Dim name = txtname.Text
Dim dt As New DataTable
dt.Columns.Add("ID", GetType(Integer))
[Code] .....

At the moment I have sometime like the code above. in the real program, it is not just name and it is not just one datatable so i just mock up some code. And this code for aspx.
<asp:TextBox ID="txtname" runat="server">
</asp:TextBox><asp:Button ID="Button1" runat="server" Text="Button" />
<asp:GridView ID="GridView1" runat="server">
</asp:GridView>

Add Rows To A Datatable With Parallel.for?

Jul 13, 2010

I have this sub :

Private Sub error_out(ByVal line As Integer, ByVal err_col As Integer, ByVal err_msg As String)
Dim ln = t_erori.Rows.Add

[Code]....

I suspect this is because it's trying to add the same row twice.
How can i make this work ? Or what else method could I use to do this ?

I need this datatable because my app is writing some results in there, but any other method to store the results that works with parallel.for would be ok.

I have to delete on a monthly schedule from a few Tables a lot of Data (> 20.000.000 Rows). So I was thinking instead of "just" delete the items, I would like to run the delete Statement Asynchron.
