I'm trying to apply some style formatting to a datagridview at the start of my program. &nbsp;Here is the body of the method which does this:<br />
<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; MessageBox.Show(&quot;IN&quot;);<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; foreach (DataGridViewRow row in dataGridView1.Rows)<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (row.Cells[0].FormattedVal<wbr />ue.ToStrin<wbr />g() != &quot;Blah&quot;)<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; row.DefaultCellStyle.BackC<wbr />olor = Color.DarkGray;<br />
<br />
This method is called at the very end of my constructor, and does in fact pop the the &quot;IN&quot; message. &nbsp;The problem is that the cells don't change color as they should. &nbsp;I have also put a button on my form, and set the event handler to do nothing but call this same method. &nbsp;For some reason when I click on the button, the cells DO in fact change color as they should.<br />
<br />
Does anyone know why I cannot change the backColor of the cells in the constructor, but I can in some random eventHandler?

datagridview style

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
