Is there a way I can get the total height of all the rows in a DGV? I want to resize a DGV so that all rows in it are visible, so that you don't have to scroll up & down. I tried multiplying the number of rows by the row height, but that doesn't account for rows that wrap text onto multiple lines. Is this possible to do?

I have two datagridview's both are databound. First one shows items for sale and the second stores all the items that were sold. I am trying too transfer selected rows from one to the other but no matter what I keep getting told "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound."
View 2 RepliesHow do I configure the rowheights so that the top and bottom rows (menu bar and status bar) size to fit the height of their content, and the middle row (main content), fills the remaining available space in the program?I can't fix the height of the top/bottom rows because the height of their content can vary.

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

I have a custom control that includes a DataGridView control. I would like to be able to adjust the heights of the rows on the dgv to fill the custom control on the target form whenever the custom control is resized. I am able to adjust the width of the various columns so that the dgv fills the custom control, but I have not been able to adjust the row heights in a similar way. I have tried the following code in the resize event of the custom control
for i = 0 to dgv.columns.count -1
dgv.columns(i).width = newwidth
next i
[Code]....
This doesn't cause an error, but the code does not change the row height. The column width change works fine.
I am able to change the row height by changing the font size at custom control compile time. I have not tried to change the font size at runtime, since this would not achieve what I am trying to accomplish.
I suspect that my problem is that I have not set one or more of the autoresize flags properly, but I have tried all the combinations I can think of.
Ok so on regular dropdownlists and comboboxes i am able to adjust the height through the properties
However, how do you set the dropdownheight of a combobox in a datagridview??? i need it to be around 150 cuz or else it will be too long and probably wont fit on most PCs... does anyone know how i can do that???
theres no option on the GUI but i was thinking maybe through code?
im using vb.net 2010
I have placed an dgv on the form. Then in the rowtemplate property i have set the height as 26. Then i added some columns. When i Click Close button of the "add column" window, along with the columns one default row with an height of 26 is added at design time.
But when i run the application the height of the defaut row is shown as 22, but when i add a new row its height is 26.
How do you change the row height of a datagridview in the designer.I can change the header row height or the font size but the height of each data row stays the same. Does this have to be done from within the VB code?
View 6 RepliesI'm trying to get specific rows in a DataGridView to resize to the minimum height required to display my wrapped text. There's only field with multiple lines, and usually its in the vicinity of 1-2, but can get up to four. When I called[code] DataGridView1.AutoResizeRow(loadcol)[/codein a for-loop, it made every column enormous,enough to fit maybe 9 or 10. I don't want the user to have to resize columns to see pertinent data, nor to have to scroll and try to remember all the data as they edit

View 2 RepliesI have a DataGridView that I am adding rows to programmatically.Normally, when I add the first row of data the SelectionChanged event firesBut my Grid is anchored to the top and bottom of the form and when I make the form smaller such that the height of the Grid is zero, the SelectionChanged event does not fire when adding the first rowIs this by design? It doesn't seem logical to me.

How to change the height of each row of datagridview in order for it to more taller. I use this code

View 4 RepliesCan 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.

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.
how can i calculate the width of a circle at top + 1/3 height & top + 2/3 height?
View 5 RepliesI have a Windows form which contains a DataGridView within a GroupBox which is within a TabPage which is within a TabControl.The scrollbars property is set to 'Both' so that the user can scroll down to see all available rows in the grid.
I want the Windows Form to initialize to allow the user to see 7 rows but to expanded vertically to the size of 32 rows which is the maximum possible in this application.
Is there a way to size the form dynamically so the Form's Height property can be changed as the DataGridView's rowcount increases?
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:

There are two alternative ways of handling the rows in the code. The first attempt (commented away here) is probably the "nicest".
In VB.NET 2008 I've two forms 1 & 2 containing two datagridviews connected to two data source 'ACCESS 2007 tables' Now I want to select multiple rows from one datagridview (form1) & transferring these to another empty datagridview (form2) with a button_click.

how to apply to Datagridview 400 rows?
View 3 RepliesMy 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:
