RadComboBox最大绑定项数

Question

我使用绑定80000个数据表到RadComboBox，同时绑定生成的错误。

<telerik:RadComboBox ID="cboxEmployeeFrom" runat="server" >
</telerik:RadComboBox>


cboxEmployee.DataSource = dts
cboxEmployee.DataTextField = dts.Columns("Name").ToString()
cboxEmployee.DataValueField = dts.Columns("EMPNO").ToString()
cboxEmployee.DataBind()

错误是：

Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.

Answer 1

对于代码来说，80,000太多了，即使它工作了，用户也处理不了。考虑使用下面详细介绍的ShowMoreResultsBox属性。RadComboBox set number of items to display

cboxEmployee.ShowMoreResultsBox = true;
