Manipulate Data Formats within cells

How would I change the font weight and color of the values in a particular cell based on a caculcation between 2 other cells. For instance, when Accounts Receivable is less than Accounts Payable (both are grid columns) how would I format the Total revenue column so that the values in them are Red and bold and when the opposite is true, then how would I format it to bold and black?

Working with Image Columns in the Grid

I have been looking at creating an control similar to the one found in the demos for the grid view. What I need is help determining how to store an image in my SQL Server database, retrieve it as a part of an employee record, display it as in the demo, but have the ability to click on a button (possibly a column header) and then change the image. We have formal and informal shots of every employee and want to be able to toggle between the 2. Please help. I can't make a lot of since from the online demo, because I can't seem to find the Photo datasource the code is referencing and where that comes from.

Thanks,

JP

[Solved] Row BackColor does not return after mousehover

Hi,

I Have a RadGridView (ver 2009.Q3.SP1) and i am formating the rows backcolor using the following code:

    
                Private Sub RGVContacts_RowFormatting(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.RowFormattingEventArgs) Handles RGVContacts.RowFormatting  
        
                    If e.RowElement.IsOdd Then  
        
                        e.RowElement.BackColor = Color.Moccasin  
        
                    Else  
        
                        e.RowElement.BackColor = Color.FloralWhite  
        
                    End If  
        
                    e.RowElement.DrawFill = True 
        
                End Sub

After we have the mouse over a row, the row is chnaging color and after leaving the row does not return to its original color.
Also, we have the similar problem when selecting one row and then another. The previous selected row does not return to its original color.

Any help will be appreciated.

Setting properties in builder doesn't work, setting in code does

I have an issue with my grid. It seems when I set properties using the property builder the values do not appear when the program is run even though the changes appear in the preview pane. That said, I can set the same properties in code, run the program and they work.
Can anyone explain why?

Thanks,
Tom

Here's a snippet of code I used. The grid is bound to a stored procedure, which I refresh after passing in a new DeptID. The grid sits inside a panel, which is set to visible after the grid is updated.
clsDept.DeptID = DeptID
            rc = clsDept.GetTruckStatusByStation()
            Me.grdVehicle.DataSource = clsDept.TT
            Me.grdVehicle.MasterGridViewTemplate.AllowAddNewRow = False
            Me.grdVehicle.ReadOnly = True
            Me.grdVehicle.Columns(0).IsVisible = False
            Me.grdVehicle.Columns(1).HeaderText = "Vehicle"
            Me.grdVehicle.Columns(3).IsVisible = False
            Me.grdVehicle.Columns(4).FormatString = "{0:MM/dd/yyyy}"
            Me.pnlMain.Visible = True

MultiColumnComboBox contents stay on form after lost focus

I have a couple of MultiColumnComboBoxes on my form and find that when I load my form with data and set the combo value as required, if the value I set it with differs from the current selected value of the combo, then the combo opens up. This is not desired behaviour. I am setting the combo value using the .Text property, as I would with a standard combo. I have tried using other properties to set the value, but these do not actually set the value at all. Can you advise which property I should use to set the value?

Thanks
