Copying Rows And Columns From One Datagridview To Another
Apr 23, 2012I'd like to copy some rows of data from a data-bound datagridview to a different datagridview.I thought adding a row would just be like this: [code]The trouble is that, instead of copying all the data from the row and putting it in the correct cells in the other datagridview, it seems to be taking the whole row object and putting it in the first cell, so the first cell contains this: [code]And the other rows are empty. How do I make rows copy properly?

VS 2008 (DataGridView) :: Delete Successful Inserts Of Rows And Move Rows Up?
Jul 30, 2010How 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.

Copying From DataGridView With Gridlines
Apr 11, 2011I am trying to copy from a DataGridView and paste into a new Outlook email. Everything is working fine, but I was wondering if there was a way to include the gridlines from the DataGridView when copying? Right now, I'm pasting the data from the DataGridView using the dgv.GetText property. It is pasting the copied text, but is not lined up at all.
View 3 RepliesCopying Information From One DataGridView To Another?
Nov 16, 2011I was doing some refreshing on my VB.NET skills by working on a little project for a friend of mine. This program loads class information from a database on her college classes and is going to allow her to select classes to add and create her schedule for the next year. We are displaying the data in datagridviews. What I am currently having trouble with is getting the data from the one classDataGridView to transfer over to scheduleDataGridView. I am able to copy the selected data to a variable, my only problem is then getting to assign that variable in to a cell in the 2nd datagridview.Here is my current code for copying and transferring the data, it is being accessed in a button_click event.

Sep 1, 2011Can anyone tell me why "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound." I keep getting an error "Invalid Operation Exception was Unhandled" error. All I am attempting to do is allow the user to select products from a list(or a second datagridview) and have it added to the datagridview so they do not have to type in every cell since the other cells are not visible because they do not purtain to their needs. Plus they will be able to save all items at the same time.

Save Datagridview Rows As New Rows?
Apr 26, 2012It was even difficult coming up with a Question title for this.
Am not sure whether am using the right approach to my problem. See i have this datagridview that contains rows that i would like have saved back into the Database as new rows but with a column altered to a new value.
Eg
PKColumn1 FKColumn2
Column3 Column4
1 1
[Code].....
What am looking at is Change FKColumn2 (some foreign key, maybe i can also have a combo box somewhere on the form and an "import to") values to something like 2 and save the rows back to the database without loosing the original rows.
DataGridView - Nonvisible Rows Are Still Visible And The DataGridView Is Empty Despite Having A DataSource
Jul 30, 2009I have several problems with rows in a DataGridView. Background information: The DataGridView (DataGridViewCalib) is in one TabPage of a TabControl, some columns of the DataGridView are automatically DataGridViewCheckBoxColumn as the DataSource have some colums which are Boolean. This is a Windows Form written in VB.Net with Visual Studio 2008. The user loads an input data file.
The problems:
1) At first arrival in the TabPage, ShowDataGridViewCalib (code below) is called. All rows are then shown in the DataGridView, despite the code saying that some rows should not be visible. Breakpoints in the code show that the code do arrive at the Rows.Visible = False events. Despite all rows beeing shown a Watch in the debugger shows that:

There are two alternative ways of handling the rows in the code. The first attempt (commented away here) is probably the "nicest".

View 3 RepliesCannot Remove Rows In Datagridview
Aug 11, 2011My datagridview is bound to a data table. I want to filter the datagridview without affecting data table. I know one way is to use bindingsource, but binding source will use column names in its filter. But I want to enable users to enter any string in a textbox to filter. So I pass datagridview by reference to a function PassFilter which removes unwanted rows in datagridview. I can see that it does execute rows removal in datagridview. But the problem is that when datagridview is shown on the form, it is unchanged, the same as the data table. I do not understand why rows are not removed on datagridview The code is as follows:
