c# - DevExpress GridControl 行号

Question

如何用行号制作列？适用于默认 WPF dataGrid 的解决方案不适用于 DevExpress...

Answer 1

您需要向您的 gridview 添加一个 unboundcolumn，您可以从设计器或代码中执行此操作。

var col = gridView1.Columns.Add();
col.FieldName = "counter";
col.Visible = true;
col.UnboundType = DevExpress.Data.UnboundColumnType.Integer;
gridView1.CustomUnboundColumnData += gridView1_CustomUnboundColumnData;

void gridView1_CustomUnboundColumnData(object sender, DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e)
{
    if (e.IsGetData)
        e.Value = e.ListSourceRowIndex+1;
}

Answer 2

将列标题设置为“#”，然后将此事件添加到 gridView1

    private void gridView1_CustomColumnDisplayText(object sender, DevExpress.XtraGrid.Views.Base.CustomColumnDisplayTextEventArgs e)
    {
        if (e.Column.Caption == "#")
        {
            e.DisplayText = (e.RowHandle + 1).ToString();
        }
    }
