Changing DataGridView Row Height?
Feb 9, 2011
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.

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?

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?

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?

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.

I'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

I 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.
With DataGridView1
.Rows.Clear()
.Columns.Clear()

I 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?

In my datagridview, I want to be able to change the value of comboBox1 depending on what the user selects in comboBox2 I had this working correctly, however if I move onto a new line in my gridview and select a different value in the second row it changes the previous row also.In the below code the correct values are generated in the combo boxs, however when I move onto a new line in my datagridview and choose a different value from my comboBox I get this error:
"The Following exception occurred in the DataGridView System.ArgumentException: DataGridViewComboBoxCell value is not valid To replace this default dialog please handle the DataError event."

I am currently reading a table from Access database and displaying it a DataGridView. Here is my
Dim ConnString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source= ....db1.mdb"
Dim SQLString As String = "SELECT Cost, Average, FROM expense_summary"
[Code]....
All the files in my access data base are numeric (database cannot be changed) but I need to change the value formats in the table. I want to convert one particular cell in the table to a percent with one decimal and also display the '%' symbol. Similarly, I want to round and display a '$' symbol in another cell. How would I do that? How would I select a specific cell in this table to change?

I have a datagridview with the datasource property set to a datatable (via dataAdapter -> dataset) now within this dataview I have columns I want to change a select few of the cell types to a combobox and datetimepicker when the user ADDS new data (They cannot EDIT existing rows). I know I could manually setup each columns (see below) datasource and its type.

I have a subroutine for changing the datagridview's columns' colors on form load.Now, everytime the user change a cell's value, the cell's backcolor is changed.If the user click 'save' the program will call the subroutine for changing color.I got everything working except the part that it will return to the color on load after save. I think I should refresh my datagridview but I don't know how to do this.

I have a form with a datagridview on it. I would like to use the same grid with two different datasources (not at the same time). If I call the form this datagridview is on with one routine, I want the source to be a list (of Class). If I call it from another routine, I want the source to be a dataview. The problem is once I set the datasource the first time, it keeps that same source even when I try to change it. I'm using this code in the form with the grid:

I can pick either one of these and they work, It just doesn't change if I run it again with the other one.

I have a project due tonight and suddenly 2 of my datagridviews are acting funky while the others are fine.
I have 2 tables in an sqlce db. the first is books(id, title, copyright) and the next is publisher(id, name, bookid). I'm writing a vb.net frontend to access the data.
I have data bound datagridviews for both tables. Both have their respective ID columns hidden. The publisher dgv uses a combobox cell style to display the book title in the bookid column. So far so good.
I have suddenly run into a problem where if I have clicked in a cell on the books dgv and then click a cell on another row, the title changes to the id value. The publisher dgv also updates to show the id instead of the title.
It sounds to me like there may be a problem with the booktableadapter or bookbindingsource, but I don't know where to start looking for it. I have a 3rd dgv referencing an unrelated table, and it has no problems. The code for both the working and problematic dgvs are the same (only the control names are different).

I have a datagridview populated using a csv file. I have a column named Date. The csv file has mixup of different date formats. So I need the date column in datagridview to be in standard "MM-dd-yyyy" format. I used below code
Me.dataGridView1.Columns("Date").DefaultCellStyle.Format = "d"It didnot have any impact.
So I used the below shown code Me.dataGridView1.Columns("Date").DefaultCellStyle.Format = "MM-dd-yyyy"Still no effect.

I have a grid bound to a datatable. The grid has two boolean fields. What I want to happen is, when the user checks one field (or perhaps I change that field's value in code), I want to automatically uncheck the other field. I tried the following code, and it gives me the results I'm looking for, but only after the user leaves the row. I want it to happen when the user clicks on the cell.
