Hi,

  Even I have a similar kind of requirement.

Though i set the

.MultipleWindowDisplayStyle =

MultipleWindowDisplayStyle.Tiled

for some reason the alerts still overlap.

Do you have any other alternate solution ?

Hi  vj,

for me it works perfectly .

Check your logic for time checking the alert timings. Are you using the array or database.

MultipleWindowDisplayStyle = MultipleWindowDisplayStyle.Tiled

Hi,

  Sorry I forgot to mention that I am using more than one UltraDeskTopAlert control, I need to show the alerts in different back colors for different conditions, using a single UltraDeskTopAlert does change the back color and stacks the alerts, but the issue is that on mouse over the back color is not retained. I read about a suggestion to use more than one UltraDeskTopAlert to retain the color. Now using multiple UltraDeskTopAlert  controls i am able to retain the back color but the issue is that it overlaps the alerts one behind the other. I am not able to display them in a stacking order.

Do any one have a suggestion to fix this ?

Hello Vj_g what you have said is correct. But i haven't tried multiple creation of desktopalert windows before.Sorry , i couldn't help you.If you found the answer please provide the solution in the thread.

Hello,

You can have different color alerts from a single WinDeskTopAlert by using a draw filter.  The following code shows an example of this:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        Button b = new Button();
        b.Click += new EventHandler(b_Click);
        b.Text = "Click Me";
        b.Dock = DockStyle.Fill;
        this.Controls.Add(b);
    }

    void b_Click(object sender, EventArgs e)
    {
        this.DemonstrateAlertsWithColors();
    }
    private void DemonstrateAlertsWithColors()
    {
        UltraDesktopAlert alert = new UltraDesktopAlert();
        alert.Appearance.BackColor = Color.Green;
        alert.DrawFilter = new DesktopAlertColorDrawFilter();
        alert.MultipleWindowDisplayStyle = MultipleWindowDisplayStyle.Tiled;

        UltraDesktopAlertShowWindowInfo info;

        info = new UltraDesktopAlertShowWindowInfo("Message One", "Message One");
        info.Data = Color.Red;
        alert.Show(info);

        info = new UltraDesktopAlertShowWindowInfo("Message Two", "Message Two");
        info.Data = Color.Blue;
        alert.Show(info);

        info = new UltraDesktopAlertShowWindowInfo("Message Three", "Message Three");
        alert.Show(info);
    }
}

public class DesktopAlertColorDrawFilter : IUIElementDrawFilter
{

    #region IUIElementDrawFilter Members

    public bool DrawElement(DrawPhase drawPhase, ref UIElementDrawParams drawParams)
    {
        WindowClientAreaUIElement element = drawParams.Element as WindowClientAreaUIElement;
        if (element != null && element.WindowInfo.Data is Color)
        {
            drawParams.AppearanceData.BackColor = (Color)element.WindowInfo.Data;
        }
        return false;
    }

    public DrawPhase GetPhasesToFilter(ref UIElementDrawParams drawParams)
    {
        if (drawParams.Element is WindowClientAreaUIElement)
            return DrawPhase.BeforeDrawElement;
        return DrawPhase.None;
    }

    #endregion
}
