[Solved] ComboBox Problem

[Bhushan]

Hello,
I have two comboboxes. The second one is filled from the selection of the first.
But if I select a value in the 2nd combobox and click on somewhere else in the screen the value at the first place gets displayed other then the selected value.

Please help me to solve this problem.

Regards,

Hello Bhushan,

Have you seen the online demo which demonstrates how the comboboxes can interact with each other using client-side methods and requesting the items on demand? Checkout the following link for online demo.

Could you provide some more information about the code that you tried to achieve this, in the case of this doesn't help?

Hello Shinu,
        Thanks for the reply.
The code of the first combo is 

<

 

td class="ReportTextboxWidth">

 

 

 

<telerik:RadAjaxPanel ID="rapXDDL" runat="server">

 

 

 

<telerik:RadComboBox ID="rcbXCategory" AutoPostBack="true" runat="server" Height="100px" >

 

</telerik:RadComboBox>

 

</telerik:RadAjaxPanel>

 

</td>
The code for the 2nd combo is 

 

<

 

telerik:RadComboBox ID="rcbXValue" runat="server" Skin="Vista" CausesValidation="false">

 

 

</telerik:RadComboBox>
I have used 

<

 

telerik:AjaxSetting AjaxControlID="rcbXCategory">

 

<UpdatedControls>

 

 

<telerik:AjaxUpdatedControl ControlID="rcbXValue" LoadingPanelID="ralpLoadingPanel" />

 

 

</UpdatedControls>

 

 

 

 

</telerik:AjaxSetting>

 

 

 

 

 

 

The procedure code is given below
Private

 

 

 

 

 

 

Sub rcbXCategory_SelectedIndexChanged(ByVal o As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs) Handles rcbXCategory.SelectedIndexChanged

 

 

 

prjUtilities.populateDropdown(rcbXValue, Get_AxisValues(rcbXCategory.SelectedValue), Name, ID)

 

rcbXValue.Items.Insert(0, New RadComboBoxItem(" ", "-1"))
End Sub

 

 

 

 

 

Public

 

 

Shared Function Get_AxisValues(ByVal intSelectedValue As Integer) As IQueryable(Of User_Defined_Metric)

 

Dim db As New DBDataContext()

 

Metric = (From UDMetrics In db.User_Defined_Metrics Select UDMetrics)

 

End If

 

Return Metric

 

End Function

 

 

The binding is proper just I have a poblem selection of the value in the 2nd combo.

 

if i select a value and click somewhere else in the screen the selection changes to the 1st value.
