Kendo 网格不使用自定义下拉列表更新数据
我正在尝试使用具有内联编辑功能的 Kendo 网格,但按更新后我的数据不会更改。其他列没有问题,但是下拉数据没有更新。
我的模型类是:
public class Validation
{
public string ParentParameterName { get; set; }
public string ParameterName { get; set; }
public string ParameterTitle { get; set; }
[UIHint("DataTypeList")]
public string DataType { get; set; }
[UIHint("EvetHyir")]
public string Required { get; set; }
public List<Validation> Value { get; set; }
}
我的网格是:
@(Html.Kendo().Grid<Validation>()
.Name("keyJsonGrid")
.Columns(columns =>
{
columns.Bound(model => model.ParentParameterName).Title("Ana parametre ünvanı");
columns.Bound(model => model.ParameterTitle).Title("Parametre ünvanı");
columns.Bound(model => model.ParameterName).Title("Parametre Adı");
//columns.Bound(foo => foo.DataType).Title("TİP").EditorTemplateName("DataType").Sortable(false);
columns.Bound(p => p.DataType).Sortable(false).Width(180).EditorTemplateName("DataTypeList");
columns.Command(command => { command.Edit().Text("Düzenle"); command.Destroy().Text("Sil"); }).Width(250);
})
.Resizable(builder => builder.Columns(true))
.ToolBar(toolbar => toolbar.Create().Text("Yeni Ekle"))
.Editable(editable => editable
.Mode(GridEditMode.InLine)
.ConfirmDelete("Silinmesine emin misiniz?")
.DisplayDeleteConfirmation("Silinmesine emin misiniz?")
)
.Pageable(pageable => pageable
.Refresh(true)
.PageSizes(new int[] { 10, 25, 50, 75, 100 })
)
.Sortable(x => x.SortMode(GridSortMode.MultipleColumn))
.DataSource(dataSource => dataSource
.Ajax()
.Read(read => read.Action("GetJsonKeyList", "Key", new { KeyId = Model }))
.PageSize(25)
)
)
我的下拉列表是从枚举填充的:
@(Html.Kendo().DropDownList()
// The name of the widget has to be the same as the name of the property.
.Name("DataType")
// The value of the drop-down is taken from the EmployeeID property.
.DataValueField("Text")
.DataTextField("Text")
.AutoBind(true)
// The text of the items is taken from the EmployeeName property.
.ValuePrimitive(true)
// A list of all employees which is populated in the controller.
.BindTo((System.Collections.IEnumerable)ViewData["DataTypes"])
)
下拉列表数据填充代码:
KeyJsonDTO.DataType x = KeyJsonDTO.DataType.Integer;
ViewData["DataTypes"] = EnumToSelectList(x.GetType());
static List<SelectListItem> EnumToSelectList(Type enumType)
{
return Enum.GetValues(enumType)
.Cast<int>()
.Select(i => new SelectListItem
{
Value = i.ToString(),
Text = Enum.GetName(enumType, i),
})
.ToList();
}
当我按“编辑”按钮时,下拉列表不会显示正确的数据,当我按更新数据时,它不会更新。
I'm trying to use a Kendo grid with inline editing but my data does not change on pressing update. Other columns have no problem, but the drop down data is not updated.
My model class is:
public class Validation
{
public string ParentParameterName { get; set; }
public string ParameterName { get; set; }
public string ParameterTitle { get; set; }
[UIHint("DataTypeList")]
public string DataType { get; set; }
[UIHint("EvetHyir")]
public string Required { get; set; }
public List<Validation> Value { get; set; }
}
My grid is:
@(Html.Kendo().Grid<Validation>()
.Name("keyJsonGrid")
.Columns(columns =>
{
columns.Bound(model => model.ParentParameterName).Title("Ana parametre ünvanı");
columns.Bound(model => model.ParameterTitle).Title("Parametre ünvanı");
columns.Bound(model => model.ParameterName).Title("Parametre Adı");
//columns.Bound(foo => foo.DataType).Title("TİP").EditorTemplateName("DataType").Sortable(false);
columns.Bound(p => p.DataType).Sortable(false).Width(180).EditorTemplateName("DataTypeList");
columns.Command(command => { command.Edit().Text("Düzenle"); command.Destroy().Text("Sil"); }).Width(250);
})
.Resizable(builder => builder.Columns(true))
.ToolBar(toolbar => toolbar.Create().Text("Yeni Ekle"))
.Editable(editable => editable
.Mode(GridEditMode.InLine)
.ConfirmDelete("Silinmesine emin misiniz?")
.DisplayDeleteConfirmation("Silinmesine emin misiniz?")
)
.Pageable(pageable => pageable
.Refresh(true)
.PageSizes(new int[] { 10, 25, 50, 75, 100 })
)
.Sortable(x => x.SortMode(GridSortMode.MultipleColumn))
.DataSource(dataSource => dataSource
.Ajax()
.Read(read => read.Action("GetJsonKeyList", "Key", new { KeyId = Model }))
.PageSize(25)
)
)
My dropdown is populated from an enum:
@(Html.Kendo().DropDownList()
// The name of the widget has to be the same as the name of the property.
.Name("DataType")
// The value of the drop-down is taken from the EmployeeID property.
.DataValueField("Text")
.DataTextField("Text")
.AutoBind(true)
// The text of the items is taken from the EmployeeName property.
.ValuePrimitive(true)
// A list of all employees which is populated in the controller.
.BindTo((System.Collections.IEnumerable)ViewData["DataTypes"])
)
Dropdown data population code:
KeyJsonDTO.DataType x = KeyJsonDTO.DataType.Integer;
ViewData["DataTypes"] = EnumToSelectList(x.GetType());
static List<SelectListItem> EnumToSelectList(Type enumType)
{
return Enum.GetValues(enumType)
.Cast<int>()
.Select(i => new SelectListItem
{
Value = i.ToString(),
Text = Enum.GetName(enumType, i),
})
.ToList();
}
When I press the "Edit" button, the dropdown does not show correct data, and when I press update data, it does not update.

我怀疑您实际上正在使用您创建的下拉菜单。 “DataType”不是字段的名称。它是您保存在文件系统中的编辑器模板的名称。您可以在页面上使用控件,但据我所知,只有当它是 javascript 网格时。您需要在适当的文件夹中创建一个编辑器模板,并将控件的定义更改为 dropdownfor(m => m)。那么你就不必命名它。
I doubt you are actually using the dropdown you created. "DataType" is not the name of the field. It is the name of the editor template you save in the file system. You can use controls on page but as far as i know, only if it's a javascript grid. You need to make an editor template in the appropriate folder and change the definition of the control to be an dropdownfor(m => m). Then you don't have to name it.
