Looking to change text appearance in cell in ColumnStyle.URL Column
posted

For a speicific column in my WinGrid, I set the ColumnStyle to ColumnStyle.URL.  I am then trying to specifiy a specific font color for the cell when the row is selected.  I have tried various things such as setting the SelectedAppearance.ForeColor, and tyring to set the ButtonAppearance. ForeColor property, but haven't had any luck.  I have had luck with normal text columns, but I am guessing there must be a special method.  I was looking at FormattedLinkEditor, but wasn't having any luck.  Thank you for your help,

Mike

     Hi Mike,

        The URL only honors two states: the normal state and the LinkClicked state. So there's no selected appearance for it.

        You can acheive what you want using a DrawFilter, though, and it's a pretty simply one. Here's a simple example of what the DrawFilter might look like:


            public class SelectedURLDrawFilter : IUIElementDrawFilter
            {
                #region IUIElementDrawFilter Members

                bool IUIElementDrawFilter.DrawElement(DrawPhase drawPhase, ref UIElementDrawParams drawParams)
                {
                    // We are assuming that we got in here for the TextSectionUIElement in the
                    // BeforeDrawForeGround phase, but that's the only phase we ever return from GetPhasesToFilter.

                    // Get the grid row so we can see if it is selected.
                    // We might also want to do the same thing for the cell to see if it's selected.
                    UltraGridRow row = drawParams.Element.GetContext(typeof(UltraGridRow)) as UltraGridRow;

                    // If we got a row and it is selected
                    if (row != null && row.Selected)
                    {
                        // Change the ForeColor to Red.
                        drawParams.AppearanceData.ForeColor = Color.Red;
                    }

                    // Return false, because we want the element to do it's normal drawing, using the
                    // AppearanceData we changed.
                    return false;               
                }

                DrawPhase IUIElementDrawFilter.GetPhasesToFilter(ref UIElementDrawParams drawParams)
                {
                    // Watch for a TextSectionUIElement which is the element that draws URLs.
                    if (drawParams.Element is Infragistics.Win.FormattedLinkLabel.TextSectionUIElement)
                    {
                        // Return DrawForeGround so we can change the color.
                        return DrawPhase.BeforeDrawForeground;
                    }

                    return DrawPhase.None;
                }

                #endregion
            }
