This is how my combo box set up in aspx page

I wanted to select the value from combo box using vb.net it select the value but the selected text will always “Select  a Value” which is default value.

This is how I am change the selected value inside the code

Me.cmbTechnicalServicePerson.SelectedValue = DRProjectDetailsinfo.Item("TechnicalServicePerson")

Or Me.cmbTechnicalServicePerson.SelectedValue = 12551

But it is not selecting the text any idea

Thanks

Hi There

I have a RadComboBox

And definition look like this

<telerik:RadComboBox Filter="Contains" runat="server" ID="cmbTechnicalServicePerson" Width="420px"

        MarkFirstMatch="true" DataSourceID="DSGetTechnicalServicePerson"

        HighlightTemplatedItems="true" OnClientItemsRequested="UpdateItemCountField"

        OnDataBound="cmbTechnicalServicePerson_DataBound" OnItemDataBound="cmbTechnicalServicePerson_ItemDataBound"

        LabelWidth="100" Label="Technical Service Name:" Skin="Office2010Black" Style="position: absolute; top: 310px; left: 21px; z-index: 6500; height: 16px;" EmptyMessage="Select  a Value" TabIndex="3">

        <HeaderTemplate>

            <ul>

                <li class="col1">Name</li>

                <li class="col2">Position</li>

                <li class="col2">Unit</li>

            </ul>

        </HeaderTemplate>

        <ItemTemplate>

            <ul>

                <li class="col1">

                    <%# DataBinder.Eval(Container.DataItem, "[FULLNAME]")%></li>

                <li class="col2">

                    <%# DataBinder.Eval(Container.DataItem, "Position")%></li>

                <li class="col3">

                    <%# DataBinder.Eval(Container.DataItem, "[Department]")%></li>

            </ul>

        </ItemTemplate>

        <FooterTemplate>

            A total of

                    <asp:Literal runat="server" ID="RadComboItemsTCount" />

            items

        </FooterTemplate>

    </telerik:RadComboBox>

Some time user would like to un select the selected value but this setting  does not allow them. Initial the EmptyMessage="Select  a Value" appear but as soon as they select something they will not be able to unselect to the empty value

Can someone please give some suggestion?

Many thanks

Syed
