are you saying...


if object.Check = "true"
{}  

if so, say

if object.Check = true
{}


Same with false, "true" is a string, true is boolean.

if that is not the issue post some code.

Actually, that code should be

if(object.Check == true)
{
//...
}

Thats right, but my point is "true" is a string... I was just doing some vb6 earlier today and confused myself.

Hello

thanks for the answers.  the answer pointed me in the right direction....

my original code was

//creating column
System.Windows.Forms.DataGridBoolColumn dbc = new DataGridBoolColumn();
dbc.TrueValue = "Yes";  //-----> changed it to dbc.TrueValue = true;
dbc.FalseValue = "No";  //-----> changed it to dbc.FalseValue = false'
tableStyle.GridColumnStyles.Add(dbc);
tableStyle.GridColumnStyles[1].HeaderText = "Scaled?";
tableStyle.GridColumnStyles[1].MappingName = myDataSet.Tables[0].Columns["Scaled"].ColumnName;
