Question

我使用EntityDataSource，我在格式化日期后得到错误转换

像那样：DataFormatString="{0:dd/MM/yyyy}"

[EntityDataSourceValidationException: Error while setting property 'fromDate': 'Cannot convert the value of parameter 'fromDate' to the type 'System.DateTime'.'.]
   Microsoft.AspNet.EntityDataSource.EntityDataSourceView.ConvertProperties(IDictionary values, PropertyDescriptorCollection propertyDescriptors, ParameterCollection referenceParameters, Dictionary`2 convertedValues) +737

我的aspx：

 <telerik:GridDateTimeColumn HeaderText="تاريخ البداية" UniqueName="fromDate" SortExpression="fromDate" DataField="fromDate" DataFormatString="{0:dd/MM/yyyy}"></telerik:GridDateTimeColumn>

注意：sqlserver db中的fromDate类型为Date

Answer 1

试试：

<telerik:GridBoundColumn DataField="fromDate" DataType="System.DateTime" HeaderText="تاريخ البداية"     
  UniqueName="fromDate" DataFormatString="{0:dd/MM/yyyy}" HtmlEncode="false"/>

无法将参数'Date'的值转换为'System.DateTime'类型。
