Displaying image on an cell
posted

Hello,

I'm trying to show an image on an cell. I've created a new column and changed the DataType. and in the InitializeRow i'm saying which photo should appear, but this don´t work. The column appears empty. Here´s my code:

InitializeLayout
...
    gData.DisplayLayout.Bands[0].Columns.Add("New");
    UltraGridColumn col = gData.DisplayLayout.Bands[0].Columns["New"];
    col.DataType = typeof(Bitmap);
    col.Header.Caption = CM.GetString("New");
    col.Header.VisiblePosition = 1;
...

InitializeRow
...
    if ((bool)e.Row.Cells["ReadByAssignedTo"].Value)
        img2 = new Bitmap(Properties.Resources.newTask);
    else

        img2 = new Bitmap(Properties.Resources.oldTask);

    e.Row.Cells["New"].Value = img2;
    //e.Row.Cells["New"].Appearance.ImageBackground = img2;
...

Can you please tell me what's wrong with this code?

Thanks

    Hello,

    I have tried the following code in the InitializeRow event of the UltraGrid and it work as expected.

     if ((bool)e.Row.Cells["New"].Value)
                {
                  img2 = Image.FromFile("First.jpg");
                }
                else
                {
                   img2  = Image.FromFile("Second.jpg");
                }

    //You are able to use this one to set the Background Image
    e.Row.Cells["Image"].Appearance.ImageBackground = img2;

    //Or you the following one to show your desired image as a value

    e.Row.Cells["Image"].Value = img2; 

    So if your column is empty are you hooking you InitializeRow event to the UltraGrid?

    Please try this at your end and let me know if you have any further questions.
