在Infragistics win网格单元格中显示Rich text格式化数据

Question

如何在Ultra Win Grid单元格中显示富文本格式化文本（infragistics）。我将这些数据作为varbinary（MAX）存储在数据库中。

使用Infragistics，您有很多选择如何实现此功能。 让我告诉你最简单的方法：

1. 设置 Grid.DataSource 属性后设置列属性：

UltraGridColumn c = null;
/// initialize c here. Lets suppose that it has a "rtf" key.
c.Style = ColumnStyle.FormattedTextEditor;
((FormattedLinkEditor) c.Editor).UnderlineLinks = UnderlineLink.Always;
((FormattedLinkEditor)c.Editor).LinkClicked += new Infragistics.Win.FormattedLinkLabel.LinkClickedEventHandler(rtfColumnn_LinkClicked);
c.MaskClipMode = MaskMode.Raw;
((FormattedLinkEditor) c.Editor).TreatValueAs = TreatValueAs.FormattedText;

1. 允许用户以rtf文本打开链接：

private void rtfColumnn_LinkClicked(object sender, Infragistics.Win.FormattedLinkLabel.LinkClickedEventArgs e)
{
    e.OpenLink = true;
}

1. 订阅活动 BeforeEnterEditMode ：

bindingGrid.BeforeEnterEditMode += this.Grid_BeforeEnterEditMode;

1. 并显示一个很好的infragistics rtf编辑器而不是incell编辑：

private void Grid_BeforeEnterEditMode(object sender, System.ComponentModel.CancelEventArgs e)
{
    if (Grid.ActiveCell.Column.Key=="rtf")
        {
            Infragistics.Win.SupportDialogs.FormattedTextEditor.FormattedTextUIEditorForm rtf_frm =
                new FormattedTextUIEditorForm();
            rtf_frm.Value = Grid.ActiveCell.Value;
            DialogResult dresult = rtf_frm.ShowDialog();
            if (dresult == DialogResult.OK)
            {
                Grid.ActiveCell.Value = rtf_frm.Value;
            }

            e.Cancel = true;
            return;
        }
}
