Datagridview Bound To A Datatable Setting Its Datasource Property To The Datatable
May 20, 2011I have a datagridview bound to a datatable setting its datasource property to the datatable. I would like to have a child form that contains a list of columns associated with the datatable that contains a checkbox that will allow the user to hide and show the columns ( I do not know the best control to use here) (I assume this is the easy part as All i need to do is loop through each of the datatable's columns to get the column name)
now I would like save these visible columns on some event like form_closing so that the next time the user opens the form up it will remember the settings
Asp.net - Extract/convert Information From A Listview (to A DataTable)?
Jan 4, 2010I have a relatively simple Listview that suddenly needs (due to new requirements) to have it's 'layout' extracted to a DataTable so that a common routine can convert it to an Excel spreadsheet for export purposes.The ItemTemplate is just a series of Table Rows with some text, data-bound labels and textboxes with validators in the cells.Usually, when trying to pull out a particular value (like what was entered into a text box), I use the ListViewItem's .FindControl method.
For Each objItem As ListViewItem In lvwOptions.Items
Dim objTextHrsLabor As TextBox = CType(objItem.FindControl("txtHrsOptByLabor"), TextBox)
decHours = CDec(objTextHrsLabor.Text)
Next
In this case, however, I'm trying to take all the data displayed - all the 'rows and columns' of the table that was created.Inside the ForEach / Next loop of ListViewItems, I started a ForEach/Next loop of Controls for each instance's controls but I got some really strange results returned (like controls that had a couple of table cells in them).
I get the sense I'm headed in the wrong direction. All I want is for the nicely-formatted 5-line, 6 column table to be converted to a 5-line, 6-column data table.

View 5 RepliesSave Information To Another Form?
May 2, 2012Form 1 code
Me.Validate()
Me. CustomersBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.BoardingschoolDataSet)
[code]....
Therefore that code above works perfectly as both of them saves information to the Customers table and waitingforApproval.The problem is here:When I open form2 which recieves information from WaitinforApproval database table(and I see it getting it from there as tableadapter works), I want to save the received information to the customers.So I have two data sets in here. Just like above So here I have created a button called confirm/save the data to customers. Hence I put this code in confirm button:
Form 2 code
Me.Validate()
Me. CustomersBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.BoardingschoolDataSet)
And the current dataset set for this form is �waitingforApproval.So it doesn�t save the received information from waitingforApproval into the customers�

Get Datagridview Table Row When Datagridview Datasource Is DataTable?
Dec 8, 2010My application must display some data in Datagridview (status of COM ports communication) and i Used .mdb databases before for faster search and Datagridview update. How i understand Datagridview is importing data from DataTable and data in DataTable is imported from .mdb file, so i decided to make shortcut - stop to using .mdb file (data must be erased every time application start and it is useless make .mdb file and erase it every time, becouse it is increasing even when drop is used) and using only DataTable..
I want to row in Datagridview change it color to red when it's Collumn(6).text countains %error% string..
When Error in COM port is starting, i can fast find row in DataTable for that port and write information that Error accured for that port and DataGridview automatically updates:
Dim RRow as () DataRow
RRow = ds.Select("Port = 'COM3')
RRow(0).Item(6) = "Error Opening COM3"

The user can save rows and add rows to maintain a client list, but when I release an update, I have to install it without the database file. If I install with the database file, then their current client database is replaced with a new blank database.
my issue is that I need to add columns to tables in their existing database without overwriting their current rows. For example, i have columns for client name, address, and phone number currently. On my next update, I want the user to be able to save client birthdays. Here is what I have:
