我怎样才能让一个DataGridView单元格的字体特定的颜色？ [英] How can I make a DataGridView cell's font a particular color?

问题描述

此代码工作正常，为使单元格的背景蓝色：

This code works fine for making the cell's background Blue:

DataGridViewRow dgvr = dataGridViewLifeSchedule.Rows[rowToPopulate];
dgvr.Cells[colName].Style.BackColor = Color.Blue;
dgvr.Cells[colName].Style.ForeColor = Color.Yellow;

... ...但前景色的效果不出我所料/希望：字体颜色仍然是黑色的，不发黄。

...but the ForeColor's effects are not what I expected/hoped: the font color is still black, not yellow.

我怎样才能让字体颜色发黄？

How can I make the font color yellow?

推荐答案

您能做到这一点：

dataGridView1.SelectedCells[0].Style 
   = new DataGridViewCellStyle { ForeColor = Color.Yellow};

您还可以设置任何在该单元格样式构造样式设置（字体，例如）。

You can also set whatever style settings (font, for example) in that cell style constructor.

如果你想设置一个特定的列文本颜色，你可以这样做：

And if you want to set a particular column text color you could do:

dataGridView1.Columns[colName].DefaultCellStyle.ForeColor = Color.Yellow;
dataGridView1.Columns[0].DefaultCellStyle.BackColor = Color.Blue;

更新

所以，如果你想基于具有在单元格中的值的颜色，这样的事情会做的伎俩：

So if you want to color based on having a value in the cell, something like this will do the trick:

private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
    if (dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value != null && !string.IsNullOrWhiteSpace(dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString()))
    {
        dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Style = new DataGridViewCellStyle { ForeColor = Color.Orange, BackColor = Color.Blue };
    }
    else
    {
        dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Style = dataGridView1.DefaultCellStyle;
    }
}
