Rendering problem of Custom Radcombox Asp.net

[Ragupathi]

Hi,

I have created a custom control (combo box) inheriting Telerik ComboBox. I have added some property in addition to the property provided by the Telerik.

In the design time after dragging and dropping the combobox, I tried adding an item for the combobox which resulted in the following error

Combobox - Combobox1There was an error rendering the control.

Type 'ComboboxControl.Combobox' does not have a public property named 'RadComboBoxItem'.

Source view of my control is as follows:

<cc4:Combobox ID="Combobox1" runat="server" Text="DropDownList">

    <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem1"></telerik:RadComboBoxItem>

</cc4:Combobox>

Hello Ragupathi,

When you add new RadComboBoxItem it needs to be added to the Items collection of RadComboBox first.

I suggest you modify your code as follows:

<cc4:Combobox ID="Combobox1" runat="server" Text="DropDownList">
       <Items>
            <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem1"></telerik:RadComboBoxItem>
      </Items>
</cc4:Combobox>
