Blazor Syncfusion DataGrid 查询

Answer 1

如果要在查询中应用多个条件，可以使用WhereFilter生成谓词，然后将生成的谓词传递给网格查询属性，以在网格中执行过滤操作。请参阅下面的代码片段和文档供您参考。

<SfButton Content="Apply Filter" OnClick="Filter"></SfButton><SfButton Content="Clear Filter" OnClick="ClearFilter"></SfButton><SfGrid DataSource="@Orders" Query="@QueryData" AllowPaging="true">

@code {
public List<Order> Orders { get; set; }

public Query QueryData { get; set; } = new Query();
public void  Filter()
{
    var Col1Pre = new WhereFilter();
    var predicate = new List<WhereFilter>();
    predicate.Add(new WhereFilter() { Field = "Freight", value = 2, Operator = "greaterthanorequal" });
    predicate.Add(new WhereFilter() { Field = "Freight", value = 15, Operator = "lessthanorequal" });
    Col1Pre = WhereFilter.And(predicate);
    QueryData = new Query().Where(Col1Pre);

}

public void ClearFilter()
{
    QueryData = new Query();
}

您可以链接

Where

方法来连续应用多个过滤器，这相当于 AND。
