Row/Colmun Header Formatting In DataGridView Control?
Apr 17, 2010
I have a DataGridView control on a form. I have NO formatting options at Runtime. I want to change the backcolor and forecolor of the Row and Column Headers. No matter what I do in the designer, they do not change. I can change the Font, but not the colors. I am able to change cell colors, though.

I have an application where a datagridview is used to display some data, a datatable is bounded to it, and I want to put some text in the front of some rows to indicate that they are different from others. My code checks the rows and used the following
mydatagridview.Rows.Item(iCnt).HeaderCell.Value = "A"
To set the row header values, it was fine when the data was first loaded. However, when I sort the datagridview by clicking the column header, these rowheadercell values disappear. How to keep the row header values after the sorting?

I am creating a DataGridView in code, not dropping the object on a form in the visual environment, and the row header is ugly. I have been playing around with this for a while. I would like the row header to look "normal", and it does not. The row header is slightly larger than the column headers, and the border is not showing. I also am not seeing the "*" or arrow(pencil) for current row selected.

I have a DataGridView where I would like drawing custom glyph (let's suppose a triangle) on the column header when the user click on it.
I have the property EnableHeadersVisualStyles set to False.
how to reach the desired result? Do I need to inherit from DataGridView, or DataGridViewColumn?

I have a windows application with many forms. We use the DataGridView control on most of the forms, but on a new form that I designed I have four DataGridViews. All of the DataGridViews on this form do not dipaly the Column Header Text when the form is displayed when running in the IDE. I do not receive any errors or messages. The other DataGridVeiws on other forms display their column header text just fine. I am at a loss as to why this is happining on this form.
UPDATE: If I add the desired text to the column.HeaderText property at the end of the form load event it displays the column header text. For example AssignedAmountColumn.HeaderText = "Amount" it displays Amount in the column when run from the IDE.... However it dosn't display when the property is set though the Columns property at design time.

However the row header width is very small and you cant read the header without adjusting it. What is the formatting command to automatically size the header to fit the text?

I have a datagridview which is bound to a table in a database. In said table, I have a field called Date and a field called Time, among other various fields. By default, I see that VB.NET attempts to help me by formatting the Date and Time columns for me, however I would like to do it my own way. I checked the columns' DefaultCellStyle fields and found them blank. Apparently, its current behavior is defined elsewhere. How would I go about removing the default formatting that VB.NET put in place to make room for my own?

In my form load event I am setting the defaultcellstyle formats. They are not taking hold anyone know why? None of the formatting that is expected in the code after I bind the datatable to the grid is getting done even though the code steps through it
Private Sub frmADRORD_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'wire the delegate function for incoming updates
AddHandler m_helper.DataUpdate, AddressOf UpdateGridInvoker
'bind the visual grid with the binding source

I am fixing up a visual basic program using visual studio 2005, specifically in visual basic. I am currently attempting to format the datagridview used to display data from a database. The values from the database being displayed are a mix of integers (used for displaying information such as number of units sold) and floating point values (used to display revenue, etc). I need to format all the values to display as integers (by simply truncating the decimal places, not rounding) as all (including the values that should already be integers which are appearing with two 0s following the decimal place). I have used the round function as follows round(value, 0, 1) which as I understand should get rid of all decimal places by simply truncating them, however I am still left with two 0s after the decimal place. Next, I went to the designer view and edited the columns property of the datagridview so that they are all set to be numeric with zero decimal places, yet the decimal still remains. I followed that by going back into the code and change any CType() that were decimal to Integer and still no change.

I'm looping through rows in a datagridview, and selecting a cell from the 3rd column each time:
Dim customer_name as String
For Each dgvr As DataGridViewRow In myDataGridView.Rows
customer_name= dgvr.Cells(2).Value
'....
next dgvr
However, I'd really like to make it dynamic, in case a new column gets added to the grid, so that I need the 4th column, not the 3rd. I'd like to use the column's header text. So something like...
customer_name= dgvr.Cells("Customer").value
Can this be done?

At runtime, I am adding a DataGridView to a windows form. The final column is a DataGridViewImageColumn:
Dim InfoIconColumn As New DataGridViewImageColumn
MyDataGridView.Columns.Insert(MyDataGridView.Columns.Count, InfoIconColumn)
Adding the following code will get my Information Icon (bitmap) to display in each of the column cells but NOT the column header:
Dim InfoIcon As New Bitmap("C:MyPathInfoIcon.bmp")
InfoIconColumn.Image = InfoIcon
Also, it is worth noting that the image displays 'perfectly' in the cells i.e. it is sized correctly to fit the cell.
However, I cannot find a way to add the same image to the column header cell. After some googling I used the following code which placed the image in the header cell but left me with two problems:
The image did not 'auto-size' to the column headercell in the same way it did when added to the column cells. The image was slightly larger and blurred.
By using the _CellPainting event slowed down performance i.e. when hovering over the DataGridView to highlight the selected row the highlighting lagged behind where my mouse was placed.
Here is the code:
[Code]...
Does anybody know of a way to solve my problem and get a nicely sized, sharp image into a DataGridViewImageColumn headercell at runtime?

I'm trying to render a checkbox in a datagridview column header so that when the checkbox is checked/unchecked all the cells in that column should be checked/unchecked accordingly.The datagridview is bound to a database table but the column containing the checkbox header cell is unbound. The problem is, whenever i click the header checkbox, all the cells in that column are checked but the header checkbox itself gets invisible. If I click the HEADER (though the checkbox is invisible, still I can click the header) again, all the cells in the column below are unchecked and the header checkbox becomes visible and unchecked. Everything is happening as expected except the visibility of the header checkbox. Why is it so?
''' <summary>

I am trying to set the "ColumnHeadersDefaultCellStyle" property to the "GoudyHvyface BT" font and it will not change from the default. I am using Visual Basic 2008.
I have set the property properly with no success.
I have tried to set the property in code, using the suggestions in the MSDN and it kept throwing errors.
