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.

Below:
datBrakePointsX.Rows.Add(strA)
produces the error 'Rows cannot be programatically added to the DataGridView's rows collection when the control is databound.'
To my knowledge, this is an empty grid. I am adding data manually and the code below works if I remove the line. The problem is I need to add the next line.
Private Sub cmdAddX_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAddX.Click
' Find the first blank cell
For c As Integer = 0 To datBrakePointsX.Rows.Count
If Len(datBrakePointsX.Rows.Item(0).Cells(c).Value) = 0 Then
datBrakePointsX.Rows.Item(c).Cells(0).Value = c

Anybody have tried having fixed number (painted) of rows on a datagridview regardless of the number of rows of the datasource??? i.e. datagridview will still show 20 rows even if the the datasource have 8 rows only? like gridlines already painted as is - with/without datasource binded.

if could modify the following code for me so that it save data row by row from a DataGridView into SQl Server. Currently, the code saves data from all rows at time instead of saving only the recently added data in a row or rows when the user clicks a button.[code]...

I am using Visual Basic 10/I have 2 datagridview tables. The main datagridview can be edited by the user; adding/removing rows, changing data in text/combo columns, sort, etc. 2 columns from the second datagridview are a carbon copy of 2 columns from the main datagridview. I have achieved this by binding both datagridviews to a dataset. So that when I edit the main datagridview the effects are automatically replicated in the second datagridview.
Before I bound the datagridviews to the dataset I had a fully functional system to save the content of the datagridview to a text file and read it back in. This has now stopped working with the error message 'Can't edit a bound datagridview programmatically'.

1. I have a DataGridView box, that is connected to a MySQL database via the 'Data Source'. I am trying to do the datagridview1.rows.add("info here"), however i receive an error i cannot do this programmatically. I DO know the code to post to MySQL via the "insert into" la la la.However, I was curious if I can do this via the datagridview a bit..easier/simpler, such as a "datagridview1.rows.add(stuff)" sorta thing.
2. I am attempting to make a custom control, and as with ANY control, they have their.. settings. Example, a textbox, or label, has so you can set the Text. and color, etc.Others, have it (such as datagridview) have the little icon on the control itself, where you click it, and it opens a small window with settings.

I have a custom collection class that is bound to a data grid view object.I'd like to try to do the following from the custom element class if possible.
1) I'd like the name of the column header to be a different text than the name of the public property in the custom class. i.e. Trade_Name should read "Trade Name"
2) I'd like to try to be able to manipulate the text formatting/color of the individual collection class element's items. i.e. for a profit/loss field I'd like to have the numbers be red if they are loss and black of they are profit. I know I could do this from the datagridview object in the form, but that can be cumbersome to raise events etc.

I am trying to develop a scheduler for my workplace for which I am using a datagridview. The data displayed in the datagridview is bound to a SQL server database.
I need to be able to drag and drop rows so that the any job with a high priority and a nearer deadline can just be dragged from anywhere in the grid and dropped to the topmost point in the grid. I don't mind using two buttons (up and down) to do it either. But I am not able to figure out a way to do it.

I do a lot of programming in VS 2010 on my Windows XP Pro PC. Recently I tried testing my software on a Windows 7 Home PC. For some reason, all of the controls on my forms are slightly misplaced. I also get a bunch of unhandled exceptions I don't get on my pc. For example, one exception said it couldn't access a registry key. Another said it couldn't find the part of a path (it didnt specify which path). What's up? Why is it doing this? My Win XP PC tricks me into thinking my apps are bug free. Guess not.

I am creating a simple website using the language of VB.NET, I am having trouble with one part at the moment and could really use some help.
At the moment I have items that are stored in a database, when the homepage loads these items are added to a Gridview which allows the user to select the items they wish to add to their shopping cart. Once an item is selected from the gridview it is added to a collection. That collection is then added to a Session. This is the code I have for completing that task.[code]...

I have a button on the screen 'Next' which performs some activities, but at the end I want to move to the next row in a datagridview to show the user what record they have moved to. I expected this to be easy, using the following code:
Dim CurDGVIndx As Integer = DataGridViewPtList.CurrentRow.Index
DataGridViewPtList.Rows(CurDGVIndx + 1).Selected = True
BUT.... Yes the highlighted record is the next record using this, however the selection (where the little arrow indicator is) stays on the original row. The selector needs to move too!

Is there a way to add rows to a DGV as I want to add information from another form to the DGV. The .Rows.Add() does not work as I am told I can not add rows to a data bound grid.Short of unbinding the DGV and re writing everything, I can not see how to do it.

I cannot find how to display an error message when what I typed in the listbox field is not in the listbox collection.
For example the listbox contains the following items
1) Apple
2) Strawberry
3) Mango
If for example I type "Mongo" and then press tab to another field, a message will pop up saying I typed something not in the listbox. Anyone who knows how to code if text in textbox1 is not in listbox then blah blah blah.

I have a dgvAssetsSummary which holds data queried from the database, it hold's the AssetType column and Total column, it's grouped by AssetType, giving a summary of all the totals and what assettype they belong to.I'd like the Total column to be formatted so that there are no decimals and with commas, at present each total has four decimal places and no commas, this needs to be able to be read easily by clients. I've tried using the following code to format the column after I query the database, but to no avail.
dgvAssetsSummary.Columns("Total").DefaultCellStyle.Format = "#,#"
how to do this, I've had a bit of a look around but I can't find much. I'm currently looking at a couple of pages from the msdn library about it.

I am a programmer from Uruguay. I have read the other similar questions about my problem, but nobody has given the answer I need. I use VB .net 2005 and its datagridview. I bind it to a dataset which is populated with a table of MySql. And when I sort the numeric columns, it sorts them as string, not numbers. I have tried casting the data to integer in the sql statement, but it doesn`t work. I changed the format of the column of the datagridview to single or long but it didn't worked either. I really can't believe it is happening, it is a so common need! I thingk It should be totally automatic.
