RowCellStyle中的DevExpress DisplayFormat

Question

​

切换应用程序以使用DevExpress XtraGrid，并实现了行/单元格的自定义颜色和格式。

对于大多数零件来说，格式的应用是正确的。但是，当应用于遵循"#，###;(#，###);0“格式的小数1000时，结果是1000.0000而不是1,000。

gridView.RowCellStyle += CellFormatting;
private void CellFormatting(object sender, RowCellStyleEventArgs e)    
 {
        if (gridView.IsRowSelected(e.RowHandle))
        {
            e.Appearance.BackColor = SystemColors.Highlight;
            e.Appearance.ForeColor = SystemColors.HighlightText;
            return;
        }

        // get cell by its index
        var gridRow = gridView.GetRow(e.RowHandle);
        TLColumn columnEnum = ((BindableTextBoxColumn)e.Column).ColumnEnum;
        // get new format values 
        T row = (T)gridRow;

        e.Column.DisplayFormat.FormatString = row.GetCellFormat(columnEnum);
        e.Appearance.BackColor = row.GetCellBackColor(columnEnum);
        e.Appearance.ForeColor = row.GetCellColor(columnEnum);

 }

Answer 1

对于不使用CustomColumnDisplayText的绑定列，需要在设置DisplayFormatString之前设置FormatType。

e.Column.ColumnType 

可以显示绑定属性的类型

 private void CellFormatting(object sender, RowCellStyleEventArgs e)
 {
       // get cell by its index
        var gridRow = gridView.GetRow(e.RowHandle);
        var column = (BindableTextBoxColumn)e.Column;
        TLColumn columnEnum = column.ColumnEnum;
        // get new format values 
        T row = (T)gridRow;

        e.Column.DisplayFormat.FormatType = (column.IsNumeric) ? FormatType.Numeric : column.DisplayFormat.FormatType;
        e.Column.DisplayFormat.FormatString = row.GetCellFormat(columnEnum);
        if (gridView.IsRowSelected(e.RowHandle))
        {
            e.Appearance.BackColor = SystemColors.Highlight;
            e.Appearance.ForeColor = SystemColors.HighlightText;
            return;
        }
        e.Appearance.BackColor = row.GetCellBackColor(columnEnum);
        e.Appearance.ForeColor = row.GetCellColor(columnEnum);
}
