Remarks
The following code snippet handles the CustomizeDataRowEditor event to customize the HireDate column editor in two ways:
- Limit available hire dates for new employees.
- Prohibit hire date modification for existing employees.
<DxGrid Data="@employees" PageSize="4" ShowFilterRow="true"
CustomizeDataRowEditor="OnCustomizeDataRowEditor" >
<Columns>
<DxGridCommandColumn />
<DxGridDataColumn FieldName="FirstName" />
<DxGridDataColumn FieldName="LastName" />
<DxGridDataColumn FieldName="BirthDate" />
<DxGridDataColumn FieldName="HireDate" />
<DxGridDataColumn FieldName="Email" />
</Columns>
</DxGrid>
@code {
Employee[]? employees;
protected override async Task OnInitializedAsync() {
employees = await EmployeeData.GetData();
}
void OnCustomizeDataRowEditor(GridCustomizeDataRowEditorEventArgs e) {
if (e.FieldName == "HireDate") {
var HireDateSettings = e.EditSettings as IDateEditSettings;
if (e.IsNewRow) {
// Limit the available hire date for new employees two weeks ahead.
HireDateSettings.MinDate = @DateTime.Today;
HireDateSettings.MaxDate = @DateTime.Today.AddDays(14);
} else {
// Disable the hire date editing.
HireDateSettings.Enabled = false;
HireDateSettings.ShowDropDownButton = false;
}
}
}
}
