Also, if there is a better way to search through a datatable for specifc values that would not require iterating through the whole table to get the results

VS 2010 : Combine Similar Rows In A Datatable (the Rows Only Differ By One Column)?
May 8, 2012I 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|C213 |02300877 |Samsung

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:

Jul 8, 20091 within each section of a SplitContainer. The left hand side will be for inputing text that is copied/pasted from a word, excell, or text file.The right hand side would be for my output. What I would like it to do is return just the rows from the left hand side that contain a match to any one of the predifined strings. This will be used to search large lists of company names and circuit IDs and return the rows with matching namesSo far I have the form created, the Splitcontainer in place along with the richtextbox on each side and a submit button at the bottom.

View 1 RepliesHide Rows In A Datagrid?
Oct 13, 2011Our site is developing against a 3rd party API (Wonderware) that returns datasets and datatables from certain calls. The issue we are having with some of the calls is the data returned is more than we want to show to the end users. We are binding the data to a datagrid, and will sometimes get back 20+ columns of data we don't need to show. Is there a way to filter the datatable of columns before binding it to the datagrid? Right now we are using the datagrid to hide the columns, but I think it would be better to strip out the columns of data we don't need before binding to the grid.

I've been trying to get a loop through a row in just one column in VB.NET for a while now, and i've done my homework on it too. When i use that code above I get:
Unable to cast object of type 'System.Windows.Forms.DataGridViewRow' to type 'System.Data.DataRow'.
I saw another guide which told me to do:
For Each row As DataGridView In dgrFarms.Rows
sendtroopid = row("idColumn")
'Do Something

But that gives me the error:
Overload resolution failed because no accessible 'Item' accepts this number of arguments.
(That's a blue underline on 'Row("idColumn") )

View 1 RepliesDataGrid - How To Update Multiple Rows
Feb 27, 2012I am new to vb.net as well as programming. (Windows application) I have only one data grid, one submit button on form. Datagrid has three columns name, age, salary
User will enter data directly in a row of datagrid. After clicking on save button data will get displayed in grid as well as stored in database.
User also can update data in any row, just by changing cell data of selected row and clicking on save button.
How I can update data in datagrid just by above way? How to guess which row data has changed? If user changes data in multiple rows, how to update multiple rows in this scenario? Can I have to take one extra column in database?

When i try to delete data from the table, it is removed from the datagrid, but the change is not showing up in the actual table.As a second question, is there a way to tag the specific row and send that back to the actual database for deletion? The way i have it set now, i think would delete all instances where digit, day, and office match, instead of just the selected record.
