Hi Omer,

When does the SetGridProperties method get called?

You don't want to set the TextRendering mode in an event of the grid like BeforeCellActivate. That certainly won't work. This is the kind of property that you should ideally be setting either at design-time or very early on in the initialization of your app, like in the form's Constructor immediately following the InitializeComponent call.

Hi Mike,

     This particular grid gets refreshed every 30 seconds to display any data that might have changed. The SetGridProperties is called every time the grid is refreshed. So to answer your question; it is not called in the form's constructor.

     I did however try your suggsetion:

public

NursingProgressNotesView()

{

// This call is required by the Windows.Forms Form Designer.

.GDI;

and it didn't make a difference.

Thanks

Omer

Hi Omer,

I just tested this out in a small sample project just to make sure the grid is working as I expect, and this all seems to work fine for me.

Perhaps your column is using an Editor or an unusual Style that is preventing this from working.

I'm attaching my sample here. When I run this sample and click on the cell (there's only one), I can clearly see the text shift from GDI+ to GDI.

If I uncomment the line of code in the InitializeComponent that sets the TextRenderingMode to GDI and then run the app and click on the cell, there is no shifting.

Hi Mike,

     I can't compile your project becuase we do not have v9.2 of the Infragistics2 dlls. The latest version we have is v8.3. Would this make a difference? If not, could you please resend your project using the 8.3 version of these dlls instead?

Thanks

Omer

You can just remove the 9.2 references from the project and add the equivalent 8.3 references.

I can't see any reason why an UltraTextEditor should cause any different in the behavior here. The column will use an EditorWithText by default, so it's essentially the same thing.

The solution in

helped me.

Hi Mike,

     Sorry for the late reply. I tried your solution and it helped although it is still not 100%. However this may be good enough for our purposes. I also did NOT use the GDI TextRendering Mode. Thanks for all of your help.

     There is now another issue that I was not aware of before and I will post that in a separate thread.

Thanks again

Omer

Okay, I see the issue now. It's a pretty subtle change. The first line of text is okay, but after that the text wrapping has to change due to the decreased available width of the cell.

CellActivation doesn't seem to make any difference here, it's just the VertScrollBar that does it.

There are basically two ways you could deal with this.

1) Make the scrollbar show all the time.

2) Leave a space in the cell where the scrollbar would be.

Personally, I think it will probably make the grid look pretty cluttered to have a scrollbar always display in every cell of the column. And in fact, the grid doesn't expose any way to do this in v8.3. If you had the latest version of the controls, you could use the new UltraControlContainerEditor to embed a TextBox into the cell and leave the scrollbar on all the time. But the UltraControlContainerEditor was not available in v8.3.

Leaving a space would have to be done using a CreationFilter and this could be done in v8.3.This is actually a pretty simple CreationFilter.

        public class MyCreationFilter : IUIElementCreationFilter
        {
            #region IUIElementCreationFilter Members

            void IUIElementCreationFilter.AfterCreateChildElements(UIElement parent)
            {
                if (parent is EditorWithTextUIElement)
                {
                    UltraGridCell cell = parent.GetContext(typeof(UltraGridCell)) as UltraGridCell;
                    if (cell != null && cell.Column.Key == "Column 0")
                    {
                        EditorWithTextDisplayTextUIElement editorWithTextDisplayTextUIElement = parent.GetDescendant(typeof(EditorWithTextDisplayTextUIElement)) as EditorWithTextDisplayTextUIElement;
                        if (editorWithTextDisplayTextUIElement != null)
                        {
                            Rectangle rect = editorWithTextDisplayTextUIElement.Rect;
                            editorWithTextDisplayTextUIElement.Rect = new Rectangle(
                                rect.X,
                                rect.Y,
                                rect.Width - SystemInformation.VerticalScrollBarWidth,
                                rect.Height);
                        }
                    }
                }
            }

            bool IUIElementCreationFilter.BeforeCreateChildElements(UIElement parent)
            {
                return false;
            }

            #endregion
        }

Hi Mike,

     Thanks for your prompt response. I got your app to run by altering the references. The 2 lines of code that you are missing in the ultraGrid1_InitializeLayout function are:

band.Columns[0].CellActivation =

Activation

.ActivateOnly;

band.Columns[0].VertScrollBar =

;

     When you include these then the TextRenderingMode doesn't work as expected since the vertical scrollbar takes up some of the width of the cell. Since the dimensions of the cell change then I guess there is nothing that can be done to maintain the text formatting with and without a scrollbar. This is the issue at the heart of the problem.

Thanks

Omer
