DataGridView And XP Styles - Set The Header Columns To Speccific Colors After The Grid Is Filled/
Feb 17, 2012In 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.

DataGridView - Convert Nulls To Empty Strings And Display It In The Grid As Empty Strings
May 14, 2009I have a DataGridView that has some columns with dates. It binds to an in-memory Datatable which gets loaded from an string array of data passed back from the backend Some of the rows returned have nulls for the date columns. Solution 1: If I define the Date column in the DataTable as "string" I can easily convert those nulls to empty strings and display it in the grid as empty strings (desired results). However, if the user clicks on the date column header to sort by date, it doesn't order the rows as you want. You get a purely string sort order. Not acceptable

View 2 RepliesAdd Items In The DatagridViewComboboxColumn Of DatagridView During Runtime
Oct 11, 2011My application is in VS2008 and coded in VB.net.
I have a datagridView(DGV) on one of my form.DGV contains a column of type DatagridViewComboboxColumn.I have another column of SrNo.
Consider Table1 to be the table from where my DatagridView is filled which contains following fields SrNo,Value1,Value2.
My requirement is i want to fill the values in my DatagridViewComboboxColumn from Table1.The DatagridViewComboboxColumn's combobox should contain values of columns Value1,Value2 of Table1.
Sample data of Table1
SrNo Value1 Value2
1 2 3
2 4 5
As data in datagridView is filled from Table1 the data of SrNo column of Table1 is also populated in one of the column of DGV.
Now my DatagridViewComboboxColumn combobox should contain the values of Value1 and Value2 of Respective SrNo.
Like Row one of my DGV has SrNo 1 as first value,so the Value1 and Value2 of SrNo 1 should be added to the row's DatagridViewComboboxColumn.
Select distinct Value1,Value2 From Table1 where SrNo=DGV.items(0,DGV.currentcell.rowIndex).value.H ope this Query willl make things more clear

ComboBox Items From A DataGridView Column?
Jan 8, 2009I have a DataGridView control with two columns:
colName
colAnnounceURL
I also have a ComboBox that I need to bind to the colAnnounceURL in the DataGridView. So everytime I add new rows to the DataGridView, the ComboBox will be updated with the items in colAnnounceURL.
I have tried the following to no avail:
cboAnnounceURL.DataSource = dgvTrackers
cboAnnounceURL.DisplayMember = "colName"
cboAnnounceURL.ValueMember = "colAnnounceURL"
The code does not cause a crash but does nothing.
Both controls are visible to the user. The idea is to have DataGridView act as AnnounceURLs manager and ComboBox to set the active AnnounceURL.

Datagridview Delete Existing Items
Nov 1, 2010I have a datagridview i use to load alot of klients into a combobox. The values of the datagridview is a connection to a MySQL db.
What it's suppose to do, is to: When clicking the combobox, it should make a list from the datagridview, getting all the names from the klients.
My problem is that it gets dublicated, and will use to much memory at a moment.
I've tryed to check if the item it was about to add allready existed in the datagridview, if it was, it shoudn't add it again, however my code failed, and I'm having huge CPU and RAM useage when running this problem for more than 30mins.
My code:
Private Sub loadCustomers()
SQL = "SELECT * FROM kunder;"
Try
[Code].....
The code above is only checking for dublicated in the combobox, And I want the code to also check for dublicated items in the datagridview.
Or a way to clear the datagridview right after the items are inserted into the combobox?
