I am trying to add some styles to my datagrid such as header text, width etc ... Every time I add something like that:

DataGridTextBoxColumn txtName = new DataGridTextBoxColumn();
txtName.HeaderText = "Name";
txtName.MappingName = "CompName";
txtName.Width = 150;

After I add that piece of code no data is displayed in my datagrid. can anyone help?

Can you post the code where txtName is added to the styles collection, and where the DataGrid is bound to the data source?

//part of the code where txtName is added to the styles collection:

DataGridTableStyle myStyle = new DataGridTableStyle();
myStyle.MappingName = "dtSKU";
myStyle.BackColor = System.Drawing.Color.Wheat;
myStyle.HeaderBackColor = System.Drawing.Color.Bisque;
myStyle.HeaderForeColor = System.Drawing.Color.DarkBlue;
myStyle.AlternatingBackColor = System.Drawing.Color.Yellow;

DataGridTextBoxColumn txtName = new DataGridTextBoxColumn();
txtName.HeaderText = "Name";
txtName.MappingName = "ProdName";
txtName.Width = 150;

myStyle.GridColumnStyles.Add(txtName);
myDataGrid.TableStyles.Add(myStyle);



//part of the code where DataGrid is bound to the data source:

myLCDConnection.Open();
string strSQU = txtSQU.Text.ToString();
string strSQL = "select stk_name from fstock where stk_code like '%" + strSQU + "%'";
SqlDataAdapter adapter = new SqlDataAdapter(strSQL,myLCDConnection);
SqlCommand myCommand = new SqlCommand(strSQL,myLCDConnection);
adapter.Fill(ds, "dtSKU");
myDataGrid.DataSource = ds.Tables[0].DefaultView;            
myLCDConnection.Close();


//this code does not generate any errors and works great until i add:
DataGridTextBoxColumn txtName = new DataGridTextBoxColumn();
txtName.HeaderText = "Name";
txtName.MappingName = "ProdName";
txtName.Width = 150;

after i add this no data is displayed in a datagrid

Have you tried changing txtName.MappingName = "ProdName" to txtName.MappingName = "stk_name" ?
