Question

我正在使用Infragisitics 17.1 UltraGrid。

网格有2列。

我想要第二列的格式化字符串，如下所示。

＆＃39; 20170102123456＆＃39; =＆GT; ＆＃39; 2017-01-02 12:34:56＆＃34;

第二列的数据类型是＆＃39; string＆＃39;不是＆＃39; date＆＃39;。

此网格将包含大量数据，因此任何转换都让我担心。

但任何欢迎都是受欢迎的。

DataSoure就像下面一样。

    private void SetTestData()
    {
        DataTable dtDataSource = new DataTable("table1");
        dtDataSource.Columns.Add("OrderDate", typeof(DateTime));
        dtDataSource.Columns.Add("RequiredDate", typeof(string));
        ultraGrid1.DataSource = dtDataSource;

        DataRow rowNew = dtDataSource.NewRow();
        rowNew["OrderDate"] = DateTime.Now;
        rowNew["RequiredDate"] = "20170101123456";
        dtDataSource.Rows.Add(rowNew);
    }

我初始化网格就像下面一样，

    private void UltraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
    {
        // Fit columns
        e.Layout.AutoFitStyle = AutoFitStyle.ExtendLastColumn;

        // Set date formats
        e.Layout.Bands[0].Columns["OrderDate"].Format = "yyyy-MM-dd HH:mm:ss";
        e.Layout.Bands[0].Columns["RequiredDate"].Format = "yyyy-MM-dd HH:mm:ss";
    }

第一列工作正常，但第二列没有。

如何在下面显示第二列？

＆＃39; 20170102123456＆＃39; =＆GT; ＆＃39; 2017-01-02 12:34:56＆＃34;

UltraGrid无法单独进行此对话。在这种特定情况下你可以做的是实现你自己的自定义IEditorDataFilter。为此，请更改您的InitializeLayuot：

然后像这样创建自定义DataFilter：

private void UltraGrid1_InitializeLayout(object sender, InitializeLayoutEventArgs e)
{
    // Fit columns
    e.Layout.AutoFitStyle = AutoFitStyle.ExtendLastColumn;

    // Set date formats
    e.Layout.Bands[0].Columns["OrderDate"].Format = "yyyy-MM-dd HH:mm:ss";

    //  You do not need this as the column data type is string 
    //e.Layout.Bands[0].Columns["RequiredDate"].Format = "yyyy-MM-dd HH:mm:ss";

    //  Set the column's editor DataFilter instead
    e.Layout.Bands[0].Columns["RequiredDate"].Editor.DataFilter = new DF();
}

Infragistics UltraGrid，我想要一个来自字符串值
