On my DGV, I have a Tool in a TextBox column. The tool has a proper name (tool.Name = “clear”).
The event handler fetches the cell
var cell = ((DataGridView)sender).Rows[e.RowIndex].Cells[e.ColumnIndex];
and set its value to empty
cell.Value = string.Empty;
The debugger shows that each step does what it’s supposed to do but the fact is the DGV cell shows the same content (if I set it to “Abc”, after running the tool it shows “Abc” all the same)

Hi Tiago,
It changes the value of the cell, but you don’t see it because the editor is in front of it. Try to change the editor:
((DataGridView)sender).EditingControl.Text = “”;
It’s the same in WinForms. Cell.Value is always the stored value. Cell.EditedFormattedValue is the value in the editor – if in edit mode – or the cell, but it’s read-only.
Best,
Luca
Changed the handler to
private void dataGridView1_CellToolClick(object sender, DataGridViewToolClickEventArgs e)
{
var cell = ((DataGridView)sender).Rows[e.RowIndex].Cells[e.ColumnIndex];
cell.Value = string.Empty;
((DataGridView)sender).EditingControl.Text = cell.Value.ToString();
}
and now it works.
