Datagridview Delete An Extra Row
Feb 10, 2010
I have a VB 2008 program over the Northwind DB customer table.It uses LINQ to add, delete and edit records.
So I load everything into a datatable/dataset first.The Add and Delete occurs when the buttons are clicked on a binding navigator. The edit occurs when a cell is changed, and that row is clicked off. I've set the Customer ID field as the primary key in the DT. I then bind everything together with a binding mavigator.
So far so good, Adding & Editing works nicely the DGV & customer table . [code]...

Why does the code below result in 3 rows in my datagrid when there is only 2 rows in my CSV file? I end up with 2 populated rows and one empty row. The CSV file only contains 2 lines. I suspect the logic of the code below.
Do While Read()
row = New DataGridViewRow()
For Index = 0 To FieldCount - 1

I have a datagridview that is being loaded from a dataset. This dataset is the result of a SQL Statement (which could be my problem). The MS Access Client table is the main table and contains 2 records, however, after loading the dataset, the row count is 3.
Below is the procedure where I load the dataset and then the DGV.
Public Function LoadClientDataSet()
Try
strSQL = "SELECT A.clientID, A.name, B.phone, B.zipCode, B.stateCD " & _

I have a datagridview with a datasource from a MySQL query. Works fine. However, I want to add an extra column and generate some data into the cells. This works fine too and shows up as intended. However, I cannot sort on that extra column and the contents of the cells in the column are cleared out if I sort on the other colums. I realize this is all because of the original datasource, but Im hoping there is a way to "connect" the extra column in somehow?
Grid_SearcherResults.DataSource = dbconnection.bSource
Grid_SearcherResults.Columns.Add("Location", "Location")
'Then some code to set the value of the cells in the new column.. etc

For a WinForms VB.Net application, I use the Bindingsource's filtering capacity to filter data, which is seen in a DataGridview. The BindingSource is from a DataSet, created using the Designer, and the data comes from a Access DB, using JetEngine and .Net 3.5. So basically:
Datagridview.Datasource = xxBindingSource
xxBindingsource.Filter = "[extended filter string with multiple columns]"
This filtering works fine, however, now I included some extra columns in the DataGridView, which I'd like to filter on, too. Of course, when I feed the manually added columns to the Filter of the BindingSource, this doesn't work out.I've done some research, and was not able to find any way to use the BindingSource's filtering syntax on the DataGridview. I'd like to use this syntax though, as I designed quite a nice UserControl and class around it, to provide smooth, fast and simple filtering capabilities.

I'm new to VB and using a datagridview for the first time. I've spent the last 2-3 days trying to get row deletion to work and can't do it. I've tried every piece of code I can find on the internets, and none of them are doing it.I have the selection mode set for full row, with a delete button on the form. Clicking it will delete the row from the DGV, but the changes are not going back to the database. Here is the code I'm using right now in my delete button event handler:

The row disappears from the DGV, but not from the database. I've gone back and started from scratch a few times now

I am using VB 2008 .net3.5. I have a form with a datagridview. The datasource of the dgv is a BindingSource. The datasource of the binding source is an object and the datamember of the binding source is a List(Of T) from that object. On formload, I create a new object with new and give the list some values and Set the datasource of the binding source to the list. The dgv loads the data but I can't delete a row. The AllowUserToDeleteRows is set to true. I select a row and nothing happens. Just to be sure I went back and did the EXACT SAME PROGRAM with C# .net2.0 and of course the dgv allows me to delete a row.
