How to hide the text for ColorEdit type?

[Tuan Lam]

When setting a CellType to GridCellTypeName.ColorEdit, our users can see the color name (ie. Silver) or the color number (ie. 72, 179, 187) on the field when they click on the cell and drag.

Is there a way to disallow selection on a column or setting the selection background and foreground color so the user cannot see those information?

Hi Tuan,

Thank you for your interest in Syncfusion products.

 

To achieve your requirement use the event CurrentCellCloseDropDown and set the backcolor to forecolor. Please refer the below code snippet for further clarification and let us know if you have any concerns.

 

Code Snippet:

 

this.gridControl1.CurrentCellCloseDropDown += new PopupClosedEventHandler(gridControl1_CurrentCellCloseDropDown);

 

void gridControl1_CurrentCellCloseDropDown(object sender, PopupClosedEventArgs e)

        {

            GridDropDownColorUICellRenderer rend = this.gridControl1.CurrentCell.Renderer as GridDropDownColorUICellRenderer;

 

            if (rend != null && !string.IsNullOrEmpty(rend.ControlText))

            {

                this.gridControl1[rend.RowIndex, rend.ColIndex].TextColor = rend.StyleInfo.Interior.BackColor;

            }

        }

Thanks & Regards,

AL.Solai.

I tried the code you gave but it doesn't work.  The CurrentCellCloseDropDown doesn't even trigger yet since user can highlight the text inside of the cell before the dropdown is closed.

Please check out the original post's attachment for detail.  This issue is related to changing the selected text color (foreground and background).
