Data grid view font does not changing dynamically

Mamta Jain

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 = newFont("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);

You Should implement like this,

this.dataGridView1.DefaultCellStyle.Font = new Font("Tahoma", 15);

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
//----
}
}
