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.

In teh MVC design pattern, Controller is strongly related to the view (GUI). IN my application i need to generated a new BrandID, i used stored procedure to retreive the highest BrandID from teh DB (The model calls the stored procedure and sends the retreival value to the Controller), then in the controller increments the BrandID by "1" to create a new brand ID. SInce, controller is strogly related to "view", should i include this "brandID increment" part in teh controller or in the model classes?
View 3 RepliesIn DGV, if the contents of the cell is truncated, the DGV shows ellipses (three dots) (...); but as the font is set to a Gujarati font, it displays a Gujarati alphabet "ઈઈઈ" instead of "..." because the Gujarati character "ઈ" is coded with the English "." (dot) character.In Gujarati font, "." can be generated with the English character "P".So, How can I change the ellipses to English "P" character? OR How can I remove the ellipses completely?I have found a similar solution by berc on Tuesday, August 31, 2010 1:33 PM :but I am not sure it is the perfect and/or the only way to do so, AND it will really work or not

View 1 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.
