Changing the font in dataGridView for specific cells.

Question

I have read the MSDN library about how to format the fonts and cell styles for all the rows and columns of a dataGridView.

What I need to be able to do is change the Font of a specific cell, or I could even get by with changing a whole row.

What I can't understand (and this might be a result of me being tired) is how you change the Font property for one row, then use the default Font properties for the remaining rows.

Basically, what I need to do is some of my cells are simply "headers" indicating a section in the data, and I need that cell (or row) to be in bold. Then, of course, return to the default properties so the rest of my data is in regular font.

Answer 1

DataGridViewCellStyle style = new DataGridViewCellStyle();
style.Font = new Font(DataGridView1.Font.FontFamily, ListMessages.Font.Size, FontStyle.Bold);
foreach (DataGridViewRow row in DataGridView1.Rows)
{
if (!(bool)row.Cells["IsRead"].Value)
{
foreach (DataGridViewCell cell in row.Cells)
cell.Style.ApplyStyle(style);
}
}

I guess this is what you're looking for. In this example a row (you can see it's cell based) is put in bold in case the IsRead-column value is set to false.
Basically you declare a style you like and bind it to specific cells.

Answer 2

The problem is I have an unbound dataGridView, so none of my columns or rows are named. My dataGridView has no column or row headers, simply cells.

What I have is typical
 string[] row0 = {"some string, "some string", someValue}
string[] row1 = ...
etc..

dataGridView.Rows.Add(row0);
dataGridView.Rows.Add(row1);
etc...

I just need a way of setting row0 to bold, then row1 back to the default font parameters. The only way I can using your method is to search the contents of the cell and then set it to bold if I find what I want. There must be a way of picking a row, and setting it. Seems you can do it with columns easily enough.

Answer 3

This is how I'm doing it...

DataGridViewCellStyle style = new DataGridViewCellStyle();

style.Font = new Font(dataGridView.Font, FontStyle.Bold);

dataGridView.Rows[0].DefaultCellStyle = style;

 

Then I can just pick any row I want ( Rows[#] )and have it displayed the way I want.

Thanks,

Answer 4

Hey Friends, Am pretty new to C# though I don't want that to discourage me. I have a situation where am using DataGridView and am having a column in my database table namely msg_status which has either a value of 0 or 1. The DataGridView should make the rows bold if msg_status value is 1 and rest of the rows with value 0 of msg_status should be normal. With that, I don't want msg_status to appear in DataGridView. My friends, I've searched a lot on internet and came up with these two ideas people had in mind about how to implement...here http://www.c-sharpcorner.com/Forums/ShowMessages.aspx?ThreadID=63866 but it doesn't help in how to make connection with the database and a lot of unanswered issues. Please help with this, thank you in advance.

Answer 5

there is a simple way to do this

DataGridV.Rows(DataGridV.Rows.Count - 1).DefaultCellStyle.Font = New Font(DataGridV.DefaultCellStyle.Font, FontStyle.Bold)
