Question

我想选择一个DevExpress MVC GridView的特定行，其中包含一个keyvalue。我在gridview中尝试了以下代码。

settings.DataBound = (sender, e) =>
    {
        MVCxGridView grid = (MVCxGridView)sender;

        grid.PageIndex = 5;

    };

    settings.PreRender = (sender, e) =>
    {

        MVCxGridView grid = (MVCxGridView)sender;

        grid.FocusedRowIndex = grid.FindVisibleIndexByKeyValue(35);



    };

我希望得到的是突出显示包含keyvalue 35的第5页的行。上面的代码对我的行选择不起作用。

请有人建议解决方案。

提前致谢。

行选择：

您可以通过以下方式通过 ASPxGridView.Selection.SetSelectionByKey 方法选择所需的DataRow：

C＃：

settings.PreRender = (sender, e) => {
    ASPxGridView gridView = (ASPxGridView)sender;

    object keyValue = 35;
    gridView.Selection.SetSelectionByKey(keyValue, true);
};

VB.NET：

settings.PreRender = _
    Sub(sender, e)
        Dim gridView As ASPxGridView = CType(sender, ASPxGridView)

        Dim keyValue As Object = 35
        gridView.Selection.SetSelectionByKey(keyValue, True)
    End Sub

您可以在DevExpress支持库中找到类似的实现：

聚焦行：

C＃：

settings.PreRender = (sender, e) => {
    ASPxGridView gridView = (ASPxGridView)sender;

    object keyValue = 35;
    gridView.FocusedRowIndex = gridView.FindVisibleIndexByKeyValue(keyValue);

};

VB.NET：

settings.PreRender = _
    Sub(sender, e)
        Dim gridView As ASPxGridView = CType(sender, ASPxGridView)

        Dim keyValue As Object = 35
        gridView.FocusedRowIndex = gridView.FindVisibleIndexByKeyValue(keyValue)
    End Sub

我得到了一个使用客户端javascript函数的解决方案。

 settings.PreRender = (sender, e) =>
   {

       MVCxGridView grid = (MVCxGridView)sender;

       var selected = 35;
       if (Convert.ToInt64(selected) > 0)
       {
           int index = grid.FindVisibleIndexByKeyValue(selected );

           grid.PageIndex = index / grid.SettingsPager.PageSize;

           grid.ClientSideEvents.Init = @"function(s, e) 
           { s.SetFocusedRowIndex(" + index + ");}";

      }

   };
