I want with a condition :
bool_badge =0
: color with RED bool_badge=1
: color with ForestGreen I have a code Correct BUT just when i click for a cell specific
My code:
foreach (DataGridViewRow dr in dataGridView1.Rows)
{
int row = this.dataGridView1.CurrentCell.RowIndex;
string valeur = dataGridView1[2, row].Value.ToString();
if (valeur == "0")
{
dataGridView1.DefaultCellStyle.SelectionBackColor = Color.Red;
}
else
{
dataGridView1.DefaultCellStyle.SelectionBackColor = Color.ForestGreen;
}
}
But I want when i execute my application , the test begin if bool_badge 0 or 1, and i have for all the gridview : color RED or ForestGreen ,
I try this code:
for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
string valeur = dataGridView1[2, i].Value.ToString();
if (valeur == "0")
{
dataGridView1.DefaultCellStyle.SelectionBackColor = Color.Red;
}
else
{
dataGridView1.DefaultCellStyle.SelectionBackColor = Color.ForestGreen;
}
}
But i have ERROR!
this is :
How can i fix it?
Very thanks,
您应该使用.Rows和.Cells属性。
string valeur = dataGridView1.Rows[i].Cells[2].Value.ToString();
You can use Datagridview's Cell_Formatting
event.
private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
if (dataGridView1.Columns[e.ColumnIndex].HeaderText == "bool_badge" && dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value != null)
// if the column is bool_badge and check null value for the extra row at dgv
{
if (dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString() == "0")
{
dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.Red;
}
if (dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString() == "1")
{
dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.ForestGreen;
}
}
}
Result will be,
Hope helps,
For helping you debugging don't do Value.ToString(); just
var value = dataGridView_XXX.Rows[rowNumber].Cells[i].value;
And
if (value == null) display your row/column index
else dataGridView_XXX.Rows[rowNumber].DefaultCellStyle.BackColor = xxx;
