SelectedValue return incorrect value when ComboBox is disabled

For example: the default SelectedValue of ComboBox is set by code-bebind to "A4", but for some reasons I need to disable the ComboBox and enable some other controls. For this case, the SelectedValue will not return the default value "A4" that I set before. But it works fine when the ComboBox is enabled.
Moreover, the SelectedValue will be lost after post-back when the ComboBox is disabled.

RadComboBox Data Clear??

Hi there,

I have two combobox, infoCat and childCat
When the ParentCombo selectedindex is changed, I want ChildCombo to re-databind (as the data is obtained through the database).

I'm having a difficulty with this. On other post, you said that I can use ItemsRequested event.. But it seems the demo code is outdated..
the script in the aspx file doesn't make sense..

within ASPX.VB File:

Protected Sub infoCat_SelectedIndexChanged(ByVal o As Object, ByVal e As Telerik.WebControls.RadComboBoxSelectedIndexChangedEventArgs) Handles infoCat.SelectedIndexChanged

PopulateChildIDs()

End Sub

Protected Sub infoCat_ItemsRequested(ByVal o As Object, ByVal e As Telerik.WebControls.RadComboBoxItemsRequestedEventArgs) Handles infoCat.ItemsRequested

PopulateInfoIDs()

End Sub

Protected Sub childCat_ItemsRequested(ByVal o As Object, ByVal e As Telerik.WebControls.RadComboBoxItemsRequestedEventArgs) Handles childCat.ItemsRequested

PopulateChildIDs()

End Sub

Private

Sub PopulateInfoIDs()

sql =

"SELECT category, category As value FROM InfoCategory"

dbCommand = db.GetSqlStringCommand(sql)

Dim ds As DataSet = db.ExecuteDataSet(dbCommand)

infoCat.DataSource = ds

infoCat.DataTextField =

"category"

infoCat.DataValueField =

"value"

infoCat.DataBind()

If infoCat.Items.Count > 0 Then

infoCat.SelectedIndex = 0

End If

Private Sub PopulateChildIDs()

If infoCat.SelectedIndex <> -1 Then

sql =

"SELECT title, title As value FROM Information WHERE category ='" & infoCat.SelectedValue & "'"

dbCommand = db.GetSqlStringCommand(sql)

Dim ds As DataSet = db.ExecuteDataSet(dbCommand)

childCat.DataSource = ds

childCat.DataTextField =

"title"

childCat.DataValueField =

"value"

childCat.DataBind()

If childCat.Items.Count > 0 Then

childCat.SelectedIndex = -1

End If

On ASPX File:

<radC:RadComboBox ID="infoCat" runat="server" AutoPostBack="True" Skin="ClassicBlue" Width="582px">

</radC:RadComboBox>

<radC:RadComboBox ID="childCat" runat="server" AutoPostBack="True" Skin="ClassicBlue" Width="582px" OnClientItemsRequested="ItemsLoaded">

</radC:RadComboBox>

</div>

I tried using script

var childCombo = <%= childCat.ClientID %>;

function PopulateChildIDs(item)

{

childCombo.SetText(

"Loading...");

childCombo.RequestItems(item.Value,

false);

}

function ItemsLoaded(combo)

{

if (combo.Items.length > 0)

{

combo.SetText(combo.Items[0].Text);

combo.Items[0].Highlight();

}

combo.ShowDropDown();

}

</script>

but not working. How come in the demo it uses (item) <-- where is the argument used..?

Can you provide me some guidance/script/solution to this?

Thanks,

Andreas

Changing background color for a particular day in Month view

I have an instance of RADScheduler that I view only in Month view. There are several days that I need to make stand out, and I'd like to do that by changing the background color of the day cell.

However, I noticed that the Scheduler does not have a DayRender event like other calendars do. Is there a way to replicate this functionality in the Scheduler? Only reason I'm using the scheduler is for the Outlook-like appointment spanning.

Any help would be appreciated.

Thanks,
Kevin

"object reference not set to instance of an object" ContexMenu Error

Hello.

I created a context menu from the radreeview properties. When I create a new ContextMenu and click in Items to add new items it works fine, but after a while (I don't know when exactly) when I try to access the Items properties of the MenuContext a visual studio message box appears with this message: "Object neference not set to an Isntance of an object".

I didn't touch the aspx markup:

    
                <telerik:RadTreeView ID="RadTreeView1" Runat="server"  
        
                    LoadingStatusPosition="BeforeNodeText"  
        
                    onclientcontextmenushowing="OnContextShowing"> 
        
                    <contextmenus> 
        
                        <telerik:RadTreeViewContextMenu ID="MenuContextMenu" runat="server"  
        
                            Flow="Horizontal"> 
        
                            <expandanimation type="OutQuart" /> 
        
                            <defaultgroupsettings expanddirection="Auto" flow="Vertical" /> 
        
                            <collapseanimation duration="200" type="OutQuint" /> 
        
                            <Items> 
        
                                <telerik:RadMenuItem runat="server" ExpandMode="ClientSide" Text="Add "  
        
                                    Value="add"> 
        
                                    <groupsettings expanddirection="Auto" flow="Vertical" /> 
        
                                </telerik:RadMenuItem> 
        
                                <telerik:RadMenuItem runat="server" ExpandMode="ClientSide" Text="Delete "  
        
                                    Value="delete"> 
        
                                    <groupsettings expanddirection="Auto" flow="Vertical" /> 
        
                                </telerik:RadMenuItem> 
        
                            </Items> 
        
                        </telerik:RadTreeViewContextMenu> 
        
                    </contextmenus> 
        
                    <Nodes> 
        
                        <telerik:RadTreeNode runat="server" ExpandMode="ClientSide"  
        
                            Text="Context Menu Test" Value="1"> 
        
                        </telerik:RadTreeNode> 
        
                    </Nodes> 
        
                    <CollapseAnimation Type="OutQuint" Duration="100"></CollapseAnimation> 
        
                    <ExpandAnimation Type="OutQuart" Duration="100"></ExpandAnimation> 
        
                </telerik:RadTreeView>

The project runs fine even when I modify the markup manually, it might be a VS interaction issue. Any ideas?

Accessing CheckboxList in Scheduler

I have installed the latest service pack and my code where I was accessing my resources (list of users displayed as checkbox) inside the RadScheduler1_FormCreated is not working anymore. I am not sure if I coded it in the correct way in the first place but I had to disable those check boxes in the EditMode.
I did the following which was working with the July service pack. Currently it can't find the checklist box with all the users. "User" is the name of my resource which is coming out of the database with the Scheduler provider model.

protected void RadScheduler1_FormCreated(object sender, SchedulerFormCreatedEventArgs e)

{
if (e.Container.Mode == SchedulerFormMode.AdvancedEdit || e.Container.Mode == SchedulerFormMode.Edit)
{

        CheckBoxList chkList = e.Container.FindControl("User") as CheckBoxList;
        if (chkList != null )
            chkList.Enabled = false;
        RadDatePicker startDate = e.Container.FindControl("StartDate") as RadDatePicker;
        if (startDate != null)
            startDate.Enabled = false;
         RadDatePicker endDate = e.Container.FindControl("EndDate") as RadDatePicker;
         if (endDate != null)
             endDate.Enabled = false;
     }
}

Please advise on how to really get hold of the items and disable them inside the form, if this is not the correct way. Are they not rendered as Checkbox list anymore?

By the way none of your Forum links are working from the demo pages anymore. You have to come to the Forum page from the main Home Page.

Thanks
