I'm having problems trying to change individual cells' colors in a datagrid. I saw a few hints which would make things easy, but unfortunately I'm working with Visual Studio 2003, so I don't have access to the newer attributes.
View 5 RepliesI have a datagrid that will get built at runtime. So i don't now how many columns I may have.I know I can do a column count, and get a list of the names. So don't think that will be a problem.What I'm trying to do is change only the CELL color, not the row, or the column, based on the value of the cell.Below is something I started with, but it clearly doesn't work.
' For Each row As DataGridViewRow In Me.QDGV.Rows
' ' Get the READY value from each row as we loop
' strExt = CStr(row.Cells.Item(4).Value)

I was looking to change the background color of a datagrid cell when the cell value changes
View 1 RepliesIs there a way to locate a cell by back color? I have a datagrid, that will populate names, on some of the cells. Some of the cells will be empty.
I have it so if there is a name in the cell, the background color will change to blue. I also can look for a specific value, and locate the value that way, and then change the color the cell or whatever.
The problem is that I have 4 different status for a cell with the same name. So for example, "Joe" name will show up in the grid. That cell background will turn blue.
The next status is "Check-In". So I can return the value "Joe" from my database with a store procedure, and look for that value of "Joe" again, and change the color to red to show he is checked in. The other 2 status I have is In Session, Session over. The problem is what if there is more than 1 "Joe"?
I think the best way is using the datagrids CellPaintings. But I can't find any other value beside a value to locate a cell on that procedure. So I thought if there is a way I can find a cell by the e.value = "Joe" and cell.backcolor = color.blue, than I can avoid having problems with multiples names.
I would be open to any other ideas, or a better way of doing this. Oh, is there a way to use tags for a cell value? I thought that might be a way was well.
So I'm using VB.NET 2005 to create an ASP page. I have a calendar object and I need to find a way to change the BackColor of the cell from a database table. I've tried every way I can think of with no luck so far.This is what I have for code so far which works for some situations but not for all the ones I would like and to hard code it would be very tedious.

I have a bunch of columns in a datagrid view (date, transaction type, amount).If the amount in a row is '150.00', I want to make that cell red.I made a Private Sub and run this after the datagridview is filled.
Private Sub ColorCells()
Dim ColumnCount As Integer
ColumnCount = dgvLedger.ColumnCount - 1[code].....
However it seems to have two bugs. When it is first run the first time when the form is loaded, it doesn't put the rows with 150.00 in it in red.If I have a button on the form and set it to run this Private Sub, then it runs through it again and will color the ones in 150 as red.If I resort the datagridview by clicking on a column, they all return to green again, and it looses the formatting.
I need to dynamicly write some VB.net code to change the colors of different cells in a TableLayoutPanel based on specific criteria. I have search for VB code to perform this but am unable to find any. I have found some C code that does it but I am unfamiliar with C.

I have a DataGridView that has been dragged over from the DataSource Tab. All works good.I need to have the background color of some of the cells changed based on other columns in that same row. Such as, have the background color of a cell Red if the Status column (not shown) relates to 90 days overdue. The next row may be different.

completely understand what it does, when the cell value is changed the color of the cell changes according to the value selected.
Now, how would i change this code so that it works when the form loads? so cells show the color when the form loads. red for unpaid and green for paid.
I would like to be able to show the defaultstyle of the cell in the form load

There is one column that is a string which contains either "YES" or "NO".When I run and display the DataGridView it displays perfectly.

Next i would like to change the background color of certain rows or records in the datagrid using values from a column.

I have a datagrid where the first column is for image button for expand purpose. The visibility of the image depends on some conditions row by row. I am trying to handle this in ItemDataBound event, and using e.item.cell(0).findcontrol("imageButton").visible = false. The first cell of this row therefore disappears even that the size is specified in the ItemStyle tag.
View 3 RepliesHow to programmatically change foreground color and make bold text in individual cell location on DataGridView control (Visual Basic)?
I use "dgMatrix.Rows(r).Cells(c).Value = x" to assign individual numeric values to individual cells in a DataGridView control. My question; is there a similar way to change foreground color and make bold the text in this cell, by specifying the individual row/column cell location?
For example; for cell (row 3, col 5) in the DataGridView make text in cell say red and bold or blue and bold so as to highlight and distinguish individual cell contents. As needed, I will also need to reset these properties (foreground back to automatic/black and font from bold back to regular); the reset could be done globally to the whole DataGridView as opposed to indiviaually by cell.
The problem is that if you never enter anything into a cell for a new row then that cell is never validated. This is a problem because I have columns that should not be null. I am doing the check in the row level validation and storing the information about which cells are empty that should not be empty. The row level validation works fine and the row level validation error indicator goes on,(red exclamation mark at the beginning of the row) but I also need a visual indicator on the individual cells that are in error.
I am thinking that setting the HasError property for the cells that are in error should cause them to display n error style (the default red border). Is there a way to this this either from XAML (perferably) or from code?Alternatively I could cause those cells to re-validate when the row editing is finished. Does anyone know how to do this?
I have a datagrid that will be accepting data from an external measuring device via the serial port. The grid is also open to editing records as well. Part of the process of making this grid user friendly is to intercept the "enter" key and move to the next cell until there is a value in the cell. This is only for some cells, other cells can be blank. I have worked out how to intercept the "enter" key from another post on this forum. Here is the code:
