如何使用 Linq 表达式在 Telerik Radgridview 中查找隐藏列

How to find hidden columns in Telerik Radgridview using Linq expression

如何从 Telerik 中找到不可见的列 Radgridview.I 已尝试使用以下表达式

RadGridView radGridView = dependencyObject as RadGridView;
var columns = radGridView.Columns.Where(x => x.IsVisible == false);

我遇到了以下异常

Error 1 'Telerik.Windows.Controls.GridViewColumnCollection' does not contain a definition for 'Where' and the best extension method overload 'Telerik.Windows.Data.QueryableExtensions.Where(System.Linq.IQueryable, Telerik.Windows.Data.FilterDescriptorCollection)' has some invalid arguments

谁能帮忙解决这个问题

var columns = new List<Telerik.Windows.Controls.GridViewColumn>(gridView.Columns);
var filteredList = columns.Where(o => o.IsVisible == false);

干杯
