How to dynamically assign Datagridview cell values based on data from my database?

问题

I have a Datagridview on my Winform project. The Datagridview is populated by data from my database.

I have 3 columns on my database table: id, name, status.

What I want to do is, based on the status string I get from my database ("Online" or "Offline"), I like to put an image in the cell, instead of just displaying a string of either Online or Offline.

ex.:If the status is Online, I'd like to have my designated online image/icon on the cell.

Anyone have ideas how to approach this?

I would do this on the DataBindingComplete event:

private void dataGridView1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
{
        foreach (DataGridViewRow r in dataGridView1.Rows)
        {
            if (r.Cells["status"].Value.ToString() == "Online")
            {
               //add image here
            }
        }
}

Your datagrid would need to attach to the DataBindingComplete as well

You can use any of the events of datagridview such as

private void dataGridView1_RowsAdded(object sender,
     DataGridViewRowsAddedEventArgs e)
{
   // write code to add image path in current cell of the row.
}

  void Item_Bound(Object sender, DataGridItemEventArgs e) 
   {
    // write code to add image path in current cell of the row.
   }
