Hi,

I need programmatically to set this cell type to be empty (no selected color) until the user selects a color.
How can this be done?

Thanks.

You can apply the __EGCS_EX_UNDEFINED_ROLE extended style for the cell. Then, when the user selects the color, just remove this style:

 // add
 pCellColor->ModifyStyleEx( __EGCS_EX_UNDEFINED_ROLE, 0 );
 
 // remove
 pCellColor->ModifyStyleEx( 0, __EGCS_EX_UNDEFINED_ROLE );

Hi,

It doesn’t work.
I added this function:

void CXXXProperty::SetDontKnow()
{
    CExtGridCellColor* pValue = (CExtGridCellColor*)ValueActiveGet();
    pValue->ModifyStyleEx(__EGCS_EX_UNDEFINED_ROLE, 0);
}

And nothing happened.

Please send a full function or a sample how to use this method.

Thanks.

Unfortunately at the moment there is no convenient and ready-to-use solution for making any cell empty without destroying the cell. It seems we need to implement this feature. So we will add a cell style that indicates that the cell is empty. Please wait a bit.

Please let me know what is your estimation on that one, because we need it ASAP.
In general we need this for every cell type.

Most probably we will implement this feature this week.
