Question

我正在尝试在下拉列表选择中为RadGrid设置过滤器中的值。

GridColumn column = RadGrid1.MasterTableView.GetColumnSafe("versionId");
column.CurrentFilterFunction = GridKnownFunction.EqualTo;
column.CurrentFilterValue = VersionsCB.SelectedValue;
RadGrid1.Rebind();

这会填充versionId过滤器框中的版本，并将其设置为“EqualTo”，但不会过滤网格。我错过了什么？

试试这个：

RadGrid1.MasterTableView.FilterExpression = "([versionId] = "+VersionsCB.SelectedValue+")";    
GridColumn column = RadGrid1.MasterTableView.GetColumnSafe("versionId");    
column.CurrentFilterFunction = GridKnownFunction.EqualTo;    
column.CurrentFilterValue = VersionsCB.SelectedValue;    
RadGrid1.Rebind();

在.aspx文件中修改RadGrid定义：

RadGrid在代码后面应用过滤器
