DataGridView And XP Styles - Set The Header Columns To Speccific Colors After The Grid Is Filled/
Feb 17, 2012
In my datagrid view I set the header columns to speccific colors after the grid is filled:
frmMain.DataGridView1.Columns(gridCols.availableCGWP).HeaderCell.Style.BackColor = My.Settings.colorCgwp
frmMain.DataGridView1.Columns(gridCols.availableLacRec).HeaderCell.Style.BackColor = My.Settings.colorFiles
frmMain.DataGridView1.Columns(gridCols.availableCM).HeaderCell.Style.BackColor = My.Settings.colorCM[code]...
This has worked fine, until I set the "Enable XP visual styles" on the project properties page. With this set, the colors dissapear from the header (although they still show up correctly in the grid). If I turn the flag off, the header colors are back to normal.

How to change the font color of the column header text in my datagridview if the entire column is read-only. I basically use a loop to add columns to my datagridview and then set the properties of the columns. But for some reason setting the DefaultCellStyle.ForeColor and HeaderCell.Style.ForeColor properties does not work. The header text is still black.[code]...

This is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?

I'm new to VS 2010 reports. I build an rdlc report based on a a table with 18 columns. From these colums, 3 of them allways have the same content so i would like to put them at the report header. When i do this i get a page for each single record, which is understandable. I worked with other tools that allow me to build report headers beased on SQL queries but it seems that VS does not allow such thing. Will be there any way to achieve what i want?

How could I change the column header of the Data Grid to center or right but not left as default? [We are talking 'bout Data Grid here, recently I always receive answers for Data Grid View instead :( ] I just want to re-align the header only, not the whole column. There's another topic discussed bout this already but it's not working in my case. Here is my code:

I have students who will be enrolled into a course. The student grid view has many columns like client_no, student_name, date_of_birth, address, etc. There are over 100000 students so I will need to filter the student grid view to find the correct student to enroll in the course. Once they are found, the user selects them and somehow moves them to the enrolled grid view. If a student drops out then they would be removed from the enrolled grid view.This process needs to be easy to understand and use. Are there any examples available or other suggestions on how to do this?

Using Visual Basic,change the backcolor of the upper left header cell (.rows(-1).columns(-1)) of a DataGridView? I would like to use a different color to indicate to the user that he/she can right click a row or column header to access the Context Menu Strip. Not all of my DGVs use a CMS, so I would like to highlight its availability for the specific DGV.

I am trying to find a way in VB using Visual Studio 2005 to have two different colored text on the same line of a DataGridView using the cell painting event
I am trying to accomplish the following.
ABC QRS
DCR BBL
Where all letter B's are Blue and all Letter R's are Red.
I have searched and found someone requesting the same. They had an example of how to do this on two different lines within the same cell but not on one line.
I don't understand the code well enough to make the change and several people that responded gave the code equivelant in C# instead of VB
The Code that they had was as follows:
If e.ColumnIndex = 0 AndAlso e.RowIndex > -1 Then
If e.Value IsNot Nothing Then
Dim lines As String() = e.Value.ToString().Split(ControlChars.Lf)

I have a big datagridview that has a list of items, that have several states, every state has a date. My dgv will look like this:
----- Date1 | Date2 | Date3 ...
It1 |
It2 |
It3 |
The same item can have multiple states in the same date, for example: The item1 enters the factory in the date1, and leaves the factory in the same date1, what i need it's that the intersection cell, have one line with the background in green with an F (means that the item enters in the factory), and in the same cell, but in another line (multiline) in the same cell i need another F but this time with the background red (means that item leaves the factory).
The usuals columns doesn't allow me to do this, i created a simple code to use a image column and then draw a image that does what i want, but i don't like the final results and it's a little slow, and when i select the full row, i don't have the usual selected cell visual effect in this columns... I was thinking to create a datagridview column with a different type (inherited) but i don't know what column to use as base column for my column, image column and then paint the content of another control in the cell or another type?
