Show Date Range In Report Header
Jan 30, 2012I have a report based on a query which requires the user to input the date range. I would like this date range to be a label in the report header. Which shows both the date and time an entry was made. For the previous reports I would run Yearly reports Display the Day ,month and year entered in a parameter query.

Show Header / Footer When Gridview Is Blank
Jun 2, 2009I realise there is a solution for this but I am struggling to get it to convert to VB correctly.I have managed to get a cascading set of dropdowns with data based upon each others results which I was really pleased with.However due to the post back the grid will disappear until the second value is selected and looks awful.Is there anyway within VB to allow the header to stick around if there is no data within the grid view?
View 2 RepliesDataGridView Index - Index Was Out Of Range?
Apr 14, 2009I am working in VB 2008 and I have set up a datagridview to display rows of data which can then be selected. When I select the first row I get the error: Index was out of range. Must be non-negative and less than the size of the collection. When I select any other row the program executes as it should. From what I have learned so far is that the DataGridView has an index of -1 and that it counts the header row as part of the index which is the -1.When I select the first row through either DataGridView1_RowHeaderMouseClick or DataGridView1_CellContentClick the index is 0 for the first record. If the index is 0 I think it would fire off, but I have no idea what is happening behind the scenes. I can check the index, so when it is 0 and the code attempts to access the row, that is when I get the message.On an index number of 1 and up the code executes fine.So, is there a way to re-index the DataGridView, or is there a work around/fix for this issue?

DataGridView - How To Set Row Header Value
Apr 22, 2010I 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?

Oct 29, 2009I 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 also am not seeing the "*" or arrow(pencil) for current row selected.

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.

View 8 Replies.net - Select Cell In DataGridView By Header Text?
Feb 29, 2012I'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?
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?
