DayPilot » Knowledge Base » Events show HTML source during image export (PNG)

Problem

The exported image (PNG, GIF, JPG) shows HTML source instead of formatted text. This can happen at the following places:

• Event text (Calendar, Month, Scheduler)
• Resource header (Scheduler)
• Upper-left corner (Scheduler)
• Column header (Calendar)
• Time header (Scheduler)
• Day header (Month)

Explanation

HTML rendering is not supported during image export.

Workaround

Use the Before*Render events to supply plain text instead of the HTML. The export can be detected by checking IsExport property.

Example 1 (Calendar events)

    protected void DayPilotCalendar1_BeforeEventRender(object sender, BeforeEventRenderEventArgs e)
    {
        if (DayPilotCalendar1.IsExport) {
          e.InnerHTML = e.Text;
        }
        else {
          e.InnerHTML = String.Format("<span style='color:green'>{0}</span>", e.Text);
        }
    }

Example 2 (Scheduler upper-left corner)

    protected void DayPilotScheduler1_BeforeResHeaderRender(object sender, DayPilot.Web.Ui.Events.BeforeHeaderRenderEventArgs e)
    {
        if (e.IsCorner)
        {
            if (DayPilotScheduler1.IsExport)
            {
                e.InnerHTML = DayPilotScheduler1.StartDate.Year.ToString();
            }
            else
            {
                e.InnerHTML = String.Format("<div style="padding: 5px; font-weight: bold; font-size: 22px; text-align: center;">{0}</div>", DayPilotScheduler1.StartDate.Year);
            }
        }
    }
