Hello,

I created a composite control and one of the properties isn't initiating on the design mode and i get ,because of other function which uses this value, an error massage.

[Bindable(true),
Category("Cells"),
DefaultValue(typeof(Color),"White"),
Description("The cells Color of the table")]
public Color CellsColor
{
get
{

EnsureChildControls();
if (((object)ViewState["CellsColor"]) == null)
return Color.White;
return ((Color)ViewState["CellsColor"]);
}
set
{

EnsureChildControls();
if (value.IsSystemColor)
DataGrid.ItemStyle.BackColor = Color.White;
else
DataGrid.ItemStyle.BackColor = (Color)value;
ViewState["CellsColor"] = DGrec.ItemStyle.BackColor;


}

i get the error massage when i drag the control to a page for the first time,
after i change the value in the property box also for the first time,
the variable gets the proper value and the error massage clears so i can see the actual control in the design view.

is someone familiar with the property initiation and why i get this error?
