Cannot Remove Rows In Datagridview

Aug 11, 2011

My 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:

Remove Selected Rows From DataGridView?

Apr 22, 2009

Private Sub btnDelProfileURL_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelProfileURL.Click
Dim Count = (dgvProfileURLs.SelectedRows.Count)
MsgBox(Count)

[code]....

This code seems right but its not working. It's giving me an "Index out of range" error. If I change the upper bound of the loop to "(Count - 2)" the code works, it just deletes all except 1 selected row. So can't figure out why "(Count - 1)" doesn't work.

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

Can 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, 2012

It 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, 2009

I 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:

[code]...

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