Can someone show me the code to making an ASPX.NET feild to be set to true open loading the data in C#.  I need to check for a feild to be populated then set this to true.  It keeps showing my template field in error.
if (License1 != string.Empty || License1 != null)
        {
           // I change the Item gridview name...
            CBAddLA1.Checked = true;



        }
        else
        {
            CBAddLA1.Checked = false;
        }

When I load the grid I would like to change the check mark to true if there is data in the field.  Otherwise, I want it to be false.  There seems to be no way to grab turn the checkbox on or off before binding the grid.

 <asp:TemplateField HeaderText="Advanced Clinical">
                    <EditItemTemplate>
                        <asp:CheckBox ID="CBAddLA1" runat="server" text='<%# Bind("LicenseAssociation1Default") %>' />
                    </EditItemTemplate>
                    <ItemTemplate>
                        <asp:CheckBox ID="CBAddLA1" runat="server" 
                            Enabled="false" />
                    </ItemTemplate>
                    <ControlStyle CssClass="standard-text" Width="100px" />
                    <FooterStyle CssClass="standard-text" />
                    <HeaderStyle BackColor="#996633" CssClass="standard-text" ForeColor="White" 
                        HorizontalAlign="Left" />
                    <ItemStyle CssClass="standard-text" />
                </asp:TemplateField>

You didn't say where you are trying to run that code from. But in order to act on row specific data you need to have code that runs at the point that each row of data gets bound to the grid. To do that you need to handle the RowDataBound event for the grid which will give you a context on which to act:

More details and sample:

    http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.rowdatabound.aspx

The sample only shows writing a dumym value to a cell, but in your case I would imaging you want something more like:
  void CustomersGridView_RowDataBound(Object sender, GridViewRowEventArgs e)
  {
      if(!string.e.Row.RowType == DataControlRowType.DataRow)
      {
            DataRowView view = e.Row.DataItem as DataRowView;
            if (view != null)
            {
                  if (!string.IsNullOrEmpty(view["SomeColumn"].ToString()))
                  {
                       CheckBox cb = e.Row.FindControl("CBAddLA1");
                       cb.Checked = true;
                  }
            }
      }
  }
