Combobox clear selection Errors out

Hello,

I have a simple example in which the javascript function is executed after a postback to clear a load-on-demand box which allows
custom text to be entered:

function Clear(){
var combo = $find("<%= RadComboBox1.ClientID %>");
combo.clearSelection();
}

When I put a break on the function, I can see that the combo object is having a value OK.
But the IE 8 browser complians the clearSelection() is not a valid method!

I tried to use the set_text() and set_value() but then I do not see the Empty message string!

Is there any way to preserve the empty message and de-select a item?

Thanks,
Sanjay

RadDatePicker vs System.Datetime()

Hi,

I am debugging an application that has just been upgraded to the ASP.NET AJAX controls from Classic. I ran into the following problem. I have these two lines of code:

RadDatePicker minValDate = new RadDatePicker();

minValDate.SelectedDate = new System.DateTime();

The second line gives me an error. "Value of '1/1/0001 12:00:00 AM' is not valid for 'SelectedDate'. 'SelectedDate' should be between 'MinDate' and 'MaxDate'.\r\nParameter name: SelectedDate"

According to MSDN "01/01/0001" is a legitimate minimum value of the System.DateTime(). So, I am wondering if there is something I am missing with my RadDatePicker.

Thanks,
Olga

RadEditor Stripping characters

Hi there,

We are using the RadEditorProvider in our DNN site, and in the RadEditor's config file, we have the ContentFilters property set to "None". When in the editor, it still seems to be changing text while toggling between HTML and design views. The text it is changing is "". Any ideas on how to absolutely stop changing any text between views? We are using the RadEditorProvider version 4.9.1 and DNN 4.9.4. The version of the Telerik.Web.UI file is 2009.3.1103.20. Any assistance would be so greatly appreciated!

Regards,

Marco

imageurl on the right

I have not been able to get the right search to answer this question. Quite simply I want the imageurl to display on the right not the left.   The formatting looks messy because the image url comes and goes misaligning the text.

I have tried to implement the ItemTemplate   but cannot get a sample that binds to RadCombo which is loaded dynamically creating combo items on the fly with search criteria.

protected void ddl_ItemsLoad(object sender, RadComboBoxItemsRequestedEventArgs e)
        {
            const int ItemsPerRequest = 40;...

I load up the items like this...   I also apply a search criteria on result to subset my response back.

                RadComboBoxItem item = new RadComboBoxItem(name, row["ID"].ToString());
                if (Manufacturer)
                    item.ImageUrl = "~/images/Manufacturer.png";
                result.Add(item);

I just cannot get the right magic to show the layout the way I want.   It works perfectly showing the image on the left, not where I want it.

Unable to load treeview

I have a tree view on my screen

<telerik:RadTreeView ID="RadTreeView1" runat="server" >

<DataBindings>

<telerik:RadTreeNodeBinding Depth="0" Expanded="true" />

</DataBindings>

</telerik:RadTreeView

And I am adding the data from the code behind

var nData = from p in db.PeforrmanceDatas

where p.PerformanceGroup.FundFamilyID == Int32.Parse(Request.QueryString["ffid"])

select new

{

p.PerformanceGroup.PerformanceGroupName,

p.Class,

p.ClassID

};

RadTreeView1.DataTextField = "Class";

RadTreeView1.DataFieldID="ClassID";

RadTreeView1.DataFieldParentID = "PerformanceGroupName";

RadTreeView1.DataSource = nData;

RadTreeView1.DataBind();

If I do not include the DataFieldParentID it will load a single level tree but when I add the hierarchy it will not load the treeview.

Problem with extra space or padding underneath header

I have a radgrid control using the vista skin. It has Scrolling enabled but it has some gray space or extra padding under the header before the first row. I also turned on filtering put the padding is still there under the filter section. Any thoughts on what causes this?
