Hi.
I have a question. I'm tryng to set a cell style (ex. style_number) for a column.

grid.Cols[columnname].CellStyle = style_number;

but the style continue to be null.

Instead if I apply the style to a cell (grid.Rows[rownumber].Cells[columnname].Style = style_number) it works.

The problem is for default values becaus doesn't apply correct style.

Can someone help me to understand?

Thanks in advance

Can you reproduce the problem in a brand new project and send it to us for the further consideration?

Hi Igor,
it's very easy to reproduce.

Make a grid, create a cell style with, for example, a formatstring ({0:N2}).
Now apply this style to the column with grid.Cols[columnname].CellStyle = style_number;

I image that this instruction apply the style to the new cell by default.

If you add row to the grid and at the column (columnname) I don't set any value , igrid set the default value.
Now If I check grid.Rows[rownumber].Cells[columnname].Style it is null.

Working with the grid I found an other problem too... always working with fixed cell style.

If i set backcolorevenrows and backcoloroddrows and after I apply some style to a column the grid lose color for even and odd rows.
I image that backcolorevenrows and backcoloroddrows is priority on the cell style

Now If Icheck grid.Rows[rownumber].Cells[columnname].Style it is null.

Yes, this is by design. The column cell style (grid.Cols[columnname].CellStyle) and the cell style of a cell in this column (grid.Rows[rownumber].Cells[columnname].Style) are two different objects. The first defines the general look of cells in the column, and it is used if a cell does not have its own style. If you assign a cell style object to the Style property of the cell, the settings of this object overrides the corresponding settings from the column cell style.

No, cell styles have precedence over these properties.

First problem.
Ok if I set value for a cell and so define the style too. But if i don't set value (and igrid set default value) I can't set style. In the second option I think it could be right
apply the generalk look of the cell (the style applied on the column)

Second problem
I don't think it is correct to manage two different style for the cell (styleodd and styleeven) when there is a property on the grid.

Send us a project demonstrating the issue we are talking about. It's hard to understand what is wrong just reading text description.
