DataGridView Column Header Text

Sep 15, 2011

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.

Print DataGridView (Text Wrap Top Header Column And Lock In Width)

Jan 31, 2012

I'm using VB.Net 2008 application program. I'm using DataGridView. I have a Print option where I need to print the DataGridView. I'm using this code for Printing and for Print Preview.

Dim MyDataGridViewPrinter As DataGridViewPrinter
Private Function SetupThePrinting() As Boolean
Dim MyPrintDialog As PrintDialog = New PrintDialog()
MyPrintDialog.AllowCurrentPage = False
MyPrintDialog.AllowPrintToFile = False
[Code] .....
Attached the class I'm using for print.

I have 10 fields showing in datagridview. As the last 5 columns header is long, the datagridview is not fitting inside 1 page (not showing all 10 fields in one single page). But is there a way i can "Text Wrap" the top header column and lock in the width, then it should print across one page perfectly. How I can "Text Wrap" the top header column and lock in the width to print across one page.

Datagridview - Sort Datagrid View Column With Numbers And Texts On Column Header Click?

Feb 13, 2012

It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?

Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?

Private Sub DataGridView1_ColumnHeaderMouseClick(sender As Object, e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DataGridView1.ColumnHeaderMouseClick

C# - Display An Image In A Datagridview Column Header?

Jul 28, 2009

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?

DataGridView Checkbox Column Header Cell (.Net 4.0)?

Sep 13, 2011

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?

Select All Cells In A DataGridView Column / Row On Header Click?

Apr 2, 2012

I have a DataGridView with SelectionMode = "CellSelect". I do this because I want the user to be able to click the Column Header and drag the column to a different DisplayIndex. They move the column by clicking and holding down the left mouse button, then moving the column. I also want the user to be able to click the column header and all the cells in the column would be selected. But if I change the SelectionMode property to "FullColumnSelect" or "ColumnHeaderSelect" the user can no longer move the column.In the code below, I can select all the cells in the DataGridView just fine, but I can't select all cells in a particular Column or Row.

VS 2010 Find Value Of Cell In Datagridview By Column Header Name?

Aug 25, 2011

I have been using this code to find the value of the cell in a datagrid view

Dim eRow As Integer
eRow = dgv.CurrentRow.Index
MessageBox.Show(dgv.Item(0, eRow).Value)

This works fine when the columns unless the user changes the order of the column.

So what I am trying to achieve is to find the value if the cell even if the order of the columns is changed. Is there a way instead of saying column (0, eRow) I can add (ColumnHeaderName = "NameHere", eRow) or something along those lines.

.net - Select Cell In DataGridView By Header Text?

Feb 29, 2012

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?
