View 2 RepliesSave Multiple Rows On Data Grid?
Mar 15, 2011<VB.Net 2010 + SQL Server 2008 + Linq To Sql>
Let's say I have ten rows on a data grid and I have changed data of three rows.
I am trying to save data by Linq for those three rows, but I am not sure how it is possible to save them.
I can do it by looping whole rows by checking each row for any change.
Is there any smarter way rather than looping by code, such as For Next.
Getting Number Of Rows In Table To Display In Database
Aug 23, 2009Any method that can effectively get the total number of rows that is StartRows to EndRows in a database table and then get the corresponding data from that row as currently I am having difficulty in retrieving out the correct row of data to the column that I am comparing. It will always get the first row of data regardless of which row I put in the handphone number which I'm comparing to. The codes below is the one which I am currently using now to detect the maxrows in the database and also to retrieve the corresponding information.
MaxRows = ds2.Tables("CustDetail").Rows.Count
MaxRows = MaxRows - 1
Dim numbers() As Integer
Dim EndAt As Integer
inc = 0
[Code] .....
I used a msgbox(n) to see the number of rows in the database but it displays only one where I have two rows in my database. The for loop is the one which will detect the number of maxrows and also retrieve out the corresponding details. But apparently this is not the appropriate way.

May 19, 2010I am almost there but for some reason I don't find the answer to my issue. Here it goes. In my application I have a form which displays a data grid view with some info I get through XML from a web server. The data grid view have as first column a Check Box colum. The second column have the information I get into a variable (from cells), one by one, to pass it to the sub with the XML command.
What I want to do is to be able to select all the rows and send the cell info of the second row (only for the selected rows) to my sub which will execute once then send the second cell info and execute the sub and so on until all the loop is complete. Currently my code works only if I delete one row at a time (sending the XML code will delete the info in the web server and update the datagridview which in return will remove the item).
