Programmatically Changing GridView Column Header Text Breaks Sorting
Jan 26, 2011I have ASP gridview bound to an Entity Data source which works no problem, however when I try to programmatically change a header columns text, it appears to break the styling and will not allow sorting either, below is how I am trapping and changing the Header row column text.
Protected Sub gv1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gv1.RowDataBound
If e.Row.RowType = DataControlRowType.Header Then
'retrieve the values from the userdeftable
e.Row.Cells(6).Text = App.Session.Company.UserDef3
End If
End Sub

View 27 RepliesDatagridview - Sort Datagrid View Column With Numbers And Texts On Column Header Click?
Feb 13, 2012It 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?

View 3 RepliesDataGridView Column Header Text
Sep 15, 2011I 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.
C# - Display An Image In A Datagridview Column Header?
Jul 28, 2009At 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, 2011I'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?

View 3 RepliesDataGridView Multiple Column Sorting
Jun 9, 2009I'm trying to sort multple colums in the DataGridView which is unbound. I would prefer to sort by using a DataTable/DataView but for some reason another developer in my team experienced other problems relating to sorting so he abandoned using the DataTable to fill the grid :(
Here is the senario: I want the user to be able to choose which columns they want sort on. The way I envisaged was to show a form with a listbox, a grid and 3 buttons (Add to sort, Remove from sort and Apply Sort).
The list box would be populated from the parent form grid column headings.
The grid will show the columns and sort direction.
Button 1 would add the selected item of the list box to the grid.
Button 2 would remove from the grid the selected row.
Button 3 would Apply the Sort in the order of the grid and the columns SortDirection.
Now I looked at How to: Customize Sorting in the Windows Forms DataGridView Control using the IComparer [URL]
how I can use the IComparer to sort on multiple columns that a user has specified or another way to sort on multiple columns using unbound data.
