Set RadComboBox to empty clientside

Is there a way to set a combo box to "empty" on the client? I mean empty like when the page is first loaded with nothing in it and the empty message is showing.

Through client side code I can clear items, clear selection and even set the combo text. But I can not figure out how to get it back to the initial "empty" state through code. If I manually delete the text in the combo box it shows the empty message but I can't seem to set it through code.

I have linked combo's and if the user clears the parent then the child needs to be cleared (set to empty) and disabled.

I have resulted to clearing the items and setting the text to "select an item". My biggest issue is that the text looks different than the empty message text. Users pick up on that stuff.

This seems like an obvious thing to have. It would be nice if there was a method that set the combo to empty like:

    
            combo.set_empty();

I thought the clearItems method would have done this but it just leaves the text in the combo blank.

Any help would be appreciated.

Thanks,
Craig

GridDateTimeColumn check for null in code behind

I have a procedure that runs in the ItemDataBound event for my grid. It's purpose is to color code a status field by checking the due date and today's date to see if the request is past due.

The due date is being displayed in a GridDateTimeColumn, however, NULL is a valid value in this field. There is no editing in this grid...it's for display purposes only.

I can't seem to figure out how to check in my code behind if there is a date in the GridDateTimeColumn or not. I tried to cast the field as a RadDatePicker using:

DirectCast(item("due_date").Controls(0), RadDatePicker)

but I get an error:

Specified argument was out of the range of valid values.
Parameter name: index

My code behind is in VB. Can you tell me how to check a GridDateTimeColumn for a null value in code behind? Thanks.

how can I put this grid to edit mode for all cells ?

<telerik:RadGrid ID="RadGrid1" runat="server" AllowMultiRowEdit="True" DataSourceID="SqlDataSource1" OnItemDataBound="RadGrid1_ItemDataBound" AllowAutomaticUpdates="True" AutoGenerateColumns="False" CellSpacing="0" GridLines="None">

<ClientSettings>

<Scrolling AllowScroll="True" />

</ClientSettings>

<MasterTableView EditMode="InPlace" CommandItemDisplay="Top" TableLayout="Fixed" AutoGenerateColumns="false">

<Columns>

<telerik:GridBoundColumn UniqueName="RxNo" HeaderText="RxNo" DataField="RxNo" >

</telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="Guidid" HeaderText="Guidid" DataField="Guidid">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="MusteriGuidid" HeaderText="MusteriGuidid" dataField="MusteriGuidid">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

            none of these methods not working for me .

    Protected Sub RadGrid1_ItemDataBound(sender As Object, e As GridItemEventArgs)
        If TypeOf (e.Item) Is GridDataItem Then
            Dim dataItem As GridDataItem = CType(e.Item, GridDataItem)
            dataItem.Edit = True
        End If
        RadGrid1.Rebind()
    End Sub

    Protected Sub RadGrid1_PreRender(sender As Object, e As EventArgs)
        ' RadGrid1.Rebind()
    End Sub

I want all cells in edit mode. there are some samples about "entering edit mode on click" but I dont want that.

How to hide Sharing button ?

Hi,

This is a problem similar to the one I had with the HD button. There is no way to hide those options when not required/needed/wanted through the control properties. I'd like to remove the share option (facebook etc.) from my video player. Setting the height/width to 0 under "Social Share" had no effect. Please advise with the required CSS (where it should just be a boolean propery setting within the control).

Thanks.

Barry
