replace true/false in datagridview columns

c#, datagridview, winforms

Solution

You can use the `CellFormatting` event of the `DataGridView`, e.g.:

void dataGridView_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
    var grid = (DataGridView)sender;
    if (grid.Columns[e.ColumnIndex].Name == "IsActive")
    {
        e.Value = (bool)e.Value ? "MY_TEXT_FOR_TRUE" : "MY_TEXT_FOR_FALSE";
        e.FormattingApplied = true;
    }
}

EDIT (as per comment):

It's very similar to what you're doing now, just remove the bound column and add a new column of the desired type and set the `DataPropertyName` properly e.g. :

this.dataGridView1.Columns.Remove("COL_TO_CUSTOMIZE");
var btnCol = new DataGridViewDisableButtonColumn();
btnCol.Name = "COL_TO_CUSTOMIZE";
btnCol.DataPropertyName = "COL_TO_CUSTOMIZE";
var col = this.dataGridView1.Columns.Add(btnCol);

Note that this append the column at the end, but you can decide the position of the column by using `dataGridView.Columns.Insert` method instead of `Add`.

Problem

I have a datagridview which I fill it as below : ``` var q= repository.GetStudents();// dataGridView1.DataSource = null; dataGridView1.Columns.Clear(); dataGridView1.DataSource = q; dataGridView1.Columns.RemoveAt(1); //Remove IsActive //Cause I want to have my own implementation dataGridView1.Columns[0].DataPropertyName = "StudentID"; dataGridView1.Columns[0].HeaderText = "Studunet ID"; dataGridView1.Columns[1].DataPropertyName = "IsActive"; dataGridView1.Columns[1].HeaderText = "Status"; ``` The "IsActive" property is of boolean Type. When the "IsActive" cell is being displayed, it show true/false. I want to replace it with my own custom value. I read this and this posts but I could not resolve my problem.
