Hello,

I work with vs 2008 and IE8.

I have a simple RadComboBox with a button.
If I tape a text in my RadComboBox, when I click on the button, the RadComboBox still always empty.

Code aspx :

<table>
  <tr>
     <td>
       <telerik:RadComboBox ID="RcmbPref" runat="server" DataSourceID="ds_pref" AutoPostBack = "true" AllowCustomText="true"  DataTextField="IDFavori" DataValueField="IDFavori" Skin="WebBlue" MarkFirstMatch="True">
       </telerik:RadComboBox>                
     </td>
     <td width="6px"> </td>
     <td>
        <asp:ImageButton ID="ImgBtn_pref" runat="server" ImageUrl="../Gen_Images/favorites_add.png" ToolTip="Ajouter une préférence d'affichage" />
     </td>                                               
   </tr>
</table>

<

 

asp:SqlDataSource ID="ds_pref" runat="server"

 

 

ConnectionString="<%$ ConnectionStrings:CsAppli %>"

 

 

SelectCommand="SELECT IDFavori FROM t_preferenceRadGrid WHERE (IDApplication = 'CEC') AND (IDSection = 'listeCL') ORDER BY IsCurrent DESC"></asp:SqlDataSource>

 



Code VB :
Private Sub ImgBtn_pref_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImgBtn_pref.Click
        Dim sNomPref As String = ""
        sNomPref = RcmbPref.Text
End Sub

Someone can see where is the problem, please ?

Anne

Hello Anne,

What is the exact problem - sNomPref string is empty or text in the RadComboBox input is empty?
If the sNomPref string is empty, could you try to remove the AutoPostBack=true from the RadComboBox declaration.

Thanks Helen for your answer

When I debug, RcmbPref.Text is empty but the input of ComboBox on the screen is not empty.

I think I found the problem.

I use a RadFilter and I want to use a comboBox to save or choose user's preferences. The preferences are save in a database (SQL server).
I think there is an incompatibility between autocomplete and SelectedIndexChanged.
When a user write a text in the combobox, the programm go in the SelectedIndexChanged and I don't know if it's a choise or text writted.

 

 

 

Private Sub RcmbPref_SelectedIndexChanged(ByVal o As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs) Handles RcmbPref.SelectedIndexChanged
    If Trim(RcmbPref.SelectedValue) <> "" Then
        Dim prefCurrent As UserPreferenceRadGrid
        prefCurrent = New UserPreferenceRadGrid(MyUser, MyApplication, MyPage, Trim(RcmbPref.SelectedValue))
        Dim SprefUser As String
        SprefUser = prefCurrent.load
        Dim LoadPersister As New GridSettingsPersister(MyRadGrid)
        LoadPersister.LoadSettings(SprefUser)
        prefCurrent.Save(SprefUser)
        MyRadGrid.Rebind()
    End If
End Sub

So I create a textBox for new preference and I use ComboBox for choose preference only.
