从 Kendo UI 网格过滤器和自动填充中获取价值
[英]Get value from Kendo UI grid filter and autofill
问题描述
我有一个 MVC web 应用程序，在我的一个观点中，我有一个 Kendo UI 网格：
@(Html.Kendo().Grid<Custodias.Models.ProjectMessageRecipientsModel>()
.Name("grid")
.Columns(columns =>
{
columns.ForeignKey(p => p.ProjectID_FK, (System.Collections.IEnumerable)ViewBag.ProjectList, "Value", "Text").Title("Project").Width(150).Filterable(filterable => filterable.Cell(e => e.Operator("eq").SuggestionOperator(FilterType.Contains).ShowOperators(false))); ;
columns.ForeignKey(p => p.ServiceUserID_FK, (System.Collections.IEnumerable)ViewBag.ServiceUserList, "Value", "Text").Title("Service User").Width(150).Filterable(filterable => filterable.Cell(e => e.Operator("eq").SuggestionOperator(FilterType.Contains).ShowOperators(false)));
columns.ForeignKey(p => p.ProcessKeyID_FK, (System.Collections.IEnumerable)ViewBag.ProcessKeyList, "Value", "Text").Title("Process Key").Width(150).Filterable(false);
columns.ForeignKey(p => p.ContactID_FK, (System.Collections.IEnumerable)ViewBag.ContactList, "Value", "Text").Title("HideContact").Width(150).Filterable(false);
columns.Bound(p => p.ContactName).Title("Contact").Width(200).Filterable(false).Hidden();
columns.Command(command => { command.Edit(); }).Width(90);
columns.Command(command => { command.Destroy(); }).Width(90);
})
.ToolBar(toolbar => toolbar.Create())
.Editable(editable => editable.Mode(GridEditMode.PopUp).Window(w => w.Title("Edit Project Message Recipients").Width(500))).Events(e => e.Edit("onPopOpen"))
.Pageable()
.Resizable(resize => resize.Columns(true))
.Sortable()
.Scrollable()
.Filterable(ftb => ftb
.Mode(GridFilterMode.Row)
.Extra(false)
)
.HtmlAttributes(new { style = "height:550px;" })
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(20)
.Events(events =>
{
events.RequestEnd("onRequestEnd");
})
.Model(model => model.Id(p => p.ProjectMessageRecipientID_PK))
.Create(update => update.Action("CreateProjectMessageRecipients", "ProjectMessageRecipients"))
.Read(read => read.Action("BindProjectMessageRecipientsModel", "ProjectMessageRecipients"))
.Update(update => update.Action("UpdateProjectMessageRecipients", "ProjectMessageRecipients"))
.Destroy(update => update.Action("DeleteProjectMessageRecipients", "ProjectMessageRecipients"))
)
)
我希望能够做的是，当有人在第一列（“项目”）中使用搜索过滤器然后添加新记录时，我希望该搜索过滤器中的值自动填充到“添加新记录”弹出窗口中的下拉列表：
那可能吗？

您可以在beforeEdit事件中处理它。 它接收 model 作为参数，用它你可以覆盖你喜欢的属性。 接下来，您可以获取dataSource的过滤器并在model中找到您需要设置的值。 例如：
var grid = $("#grid").data("kendoGrid");
grid.bind("beforeEdit", (e) => {
let filter = e.sender.dataSource.filter().filters.find(filter => filter.field === 'ProductName');
e.model.ProductName = filter.value;
});

使用 => grid.dataSource.filter() 获取网格的应用过滤器
用下面的方法检查网格过滤器长度
var grid = $("#gridID").data("kendoGrid"); if(grid.dataSource.filter()==null){ console.log(0); } else{ grid.dataSource.filter().filters.length; }
带有文本和值下拉列表的Kendo UI网格过滤器
