Data grid view font does not changing dynamically

Question

I have a windows form and having datagridview which binds to dataset dynamically  now in the form on the button click event I am changing the datagridview font appearance . I tried below code but its not effecting on Datagridview  only header part is being changing . Please recommended what I done wrong in coding. My Code private void Btn_Language_Click ( object sender  EventArgs e ) { if ( DGV_View . Font . Name == Trebuchet MS ) { DGV_View . Font = new System . Drawing . Font ( NILKANTH  12 ); this . DGV_View . DefaultCellStyle . Font = new System . Drawing . Font ( NILKANTH  12 ); } else if ( DGV_View . Font . Name == NILKANTH ) { DGV_View . Font = new System . Drawing . Font ( Trebuchet MS  11 ); } }

Hey try this You need to First get The RowIndex then Column Index and Then Set Font of Cell :) private void dataGridView1_CellClick( object sender DataGridViewCellEventArgs e) { //Get Row Index int Rowindex = e.RowIndex; //Get Column Index int CellIndex = e.ColumnIndex; //Set Font to Bold dataGridView1.Rows[Rowindex].Cells[CellIndex].Style.Font = new Font ( Arial 12 FontStyle .Bold); } Use below if you want to set Whole Row Font to Bold dataGridView1.Rows[Rowindex].DefaultCellStyle.Font = new Font ( Arial  12 FontStyle .Bold);

Can you please try something like below once : private void UpdateFont() { //Change cell font foreach(DataGridViewColumn c in dgAssets.Columns) { if( c.DefaultCellStyle.Font==Trebuchet MS) c.DefaultCellStyle.Font = new Font(Arial 8.5F GraphicsUnit.Pixel); else //---- } }
