I have the following two columns

And here's the HTML output

How come in the first case, I get a <label> tag, but in the 2nd case I don't? Is there a way to fix this?

I upgraded a .NET web application from .NET framework 2.0 to .NET framework 4.5. The Telerik controls were also upgraded, from Q3 2010 to Q3 2015. Due to the upgrade, the web application is experiencing some odd behavior which did not exist in the previous version. Mainly, the ItemCommand is not being raised at all on one of the grids. I have searched extensively and tried multiple solutions to no avail. I have included the relevant sections of code below. The source code is quite large and complex, so I won't be including all parts. 

The command that should be firing, will result in filters being displayed. The radgrid contains a radtoolbar which contains a radtollbarbutton, when the button is clicked, I am expecting the item command event to be raised and the filter dialog to be displayed.

Hi,

 I am using two DateTime Picker (set to BOTH Date&Time) and when I am trying to retrieve data from database, it is throwing an exception. From event viewer, I got this :
Stack trace:    at System.DateTime.DateToTicks(Int32 year, Int32 month, Int32 day)
   at System.DateTime..ctor(Int32 year, Int32 month, Int32 day)
   at Telerik.Web.UI.Calendar.Utils.Utility.ConvertToServerDateTimeCollection(DateTimeCollection dateTimeCollection, String inputString) in c:\Users\Administrator\Desktop\UI for ASP.NET AJAX\Telerik.Web.UI_2013_2_717_Source\RadControlsAjaxSource\Telerik.Web.UI\Calendar\Utility\Utility.cs:line 274

   at System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad)
   at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

•  We are UI for ASP.Net AJAX (Telerik version 2013.2.717.35).
• It is working fine for few TimeZone like Pacific Time but giving error in like UTC +5.30 etc.
• The error is only occurring when we are setting it to both (Date & Time ) while it is working fine in only Date Format.

I tried Debugging into Telerik Source, and I found that the exception is coming in this funtion:

/// <summary>
/// Converts an input 2D JavaScript array like [[5,10,2005],[6,10,2005],[7,10,2005]] into a DateTimeCollection.
/// </summary>
/// <param name="dateTimeCollection">The DateTimeCollection that will be filled.</param>
/// <param name="inputString">The input string.</param>
internal static void ConvertToServerDateTimeCollection(DateTimeCollection dateTimeCollection, string inputString)
{
int i, BracketCount = 0;

if (String.IsNullOrEmpty(inputString)) return;

for (i = 0; i < inputString.Length; i++)
{
if (inputString[i] == '[')
BracketCount++;
else if (inputString[i] == ']')
BracketCount--;
}
if (BracketCount != 0)
{
throw new FormatException(Constants.Exception.FormatInputJavaScriptDateException);
}

// Remove the "[" and the "]"
inputString = inputString.Replace("[", String.Empty).Replace("]", String.Empty);

string[] ArrDates = inputString.Split(",".ToCharArray());

for (i = 0; i < ArrDates.Length / 3; i++)
{
DateTime CurrentDateTime = new DateTime(Int32.Parse(ArrDates[i * 3]), Int32.Parse(ArrDates[i * 3 + 1]), Int32.Parse(ArrDates[i * 3 + 2]));
dateTimeCollection.Add(new RadDate(CurrentDateTime));
}
}

Please suggest some way to get rid from this problem. 

Thanks

Hello,

I am trying to add excel style filtering to our current application. To achieve this the solution has been upgraded with the Telerik 15.3.1111.45 upgrade.

But after adding

            gridview.AllowFilteringByColumn = true;
            gridview.EnableHeaderContextFilterMenu = true;
            gridview.FilterType = GridFilterType.HeaderContext;

to the constructor of the grid.

I saw a little change in the layout of the header column but no filtermenu button to open. (as mentioned: http://demos.telerik.com/aspnet-ajax/grid/examples/functionality/filtering/excel-like-filtering/defaultcs.aspx )

My guess is that I'm forgetting one thing that is needed to show the menu demonstrated in above link.

To be sure I'll also post the GridHeaderTemplate that we set as columnheader (and shows everything in the columnheader) (This is basically how column headers showed the info needed before excel style filtering)

        public void InstantiateIn(Control container)
        {
            // Check if column is sorted and show corresponding image
            SortingProp sort = null;
            bool hasSort = controller.CurrentSorting != null && controller.CurrentSorting.TryGetValue(prop.ID, out sort);
            if (hasSort)
            {
                var div = new HtmlGenericControl("div");
                var image = new HtmlImage { Src = "images/grid_sort_" };

                div.Attributes.Add("class", "sort");
                image.Src += sort.SortDirection == MySortDirection.Ascending ? "ascending.png" : "descending.png";

                div.Controls.Add(image);
                container.Controls.Add(div);
            }

            // Check if column is filtered and show corresponding image
            if (controller.IsPropFiltered(prop.ObjProp.ObjProp))
            {
                var image = new HtmlImage { Src = MyFileUrls.CreateSharedImageUrl(ImageRepository.Shared.filter_16, false) };
                image.Attributes.Add("class", "filter");
                container.Controls.Add(image);
            }

            var title = new HtmlGenericControl("div");
            var label = new Literal { Text = prop.ObjProp.TranslGrid };
            title.Attributes.Add("class", "title");
            title.Controls.Add(label);
            container.Controls.Add(title);
        }

I have a pannel control, where I want a specific textbox to be selected after the listbox.get_selectedItem(). but in the javascript side if I put #RadTextboxID.focus() it never comes down there and the RadTB is not selected.

MY code in the JS side

function AddNewTask() {
    $('.emptyTaskList').hide();  
    var listbox = $find('rlbTasks');
    $('#lblEditTaskSign').html('Add Task/Milestone');
    $('#lbDeleteTask').hide();
    listbox.get_selectedItem().set_selected(false);
  $( "#rtbName" ).focus();

And the page does not post back so setting it in the page_load did not help. 

I also tried :

 <telerik:RadTextBox ClientEvents-OnLoad="onClientLoad" runat="server" ID="rtbName" MaxLength="255" />                                                    

function onClientLoad(sender) // executes when loading the RadTextBox 
{
    sender.focus();
}

Did not work? how should I approach this issue?

Hello,

 I have a project that uses the RadAjaxManager all over the place and prior to the upgrade all of the controls would update just fine. Since the upgrade however none of the controls update. The only thing I get back is an error in the console when ever I do an action that should cause an Ajax update. The control bellow is one example of the many controls and pages using the RadAjaxManager

Thank you.

I have a very specific problem with the RadComboBox. I am using it in a RadWindow that is opening like a dialog, and it is near the bottom of the window, so that the expanded drop down has to open up. If I have enough items that the vertical scroll bar is used, I can select an item and move on, but if I go back to the ComboBox to change my selection, it locks and freezes the whole browser window.

I am using Q1 controls, IE Version 7.0.6001.18000.

This lockup/freeze does NOT occur in Firefox 3, and operates as expected.

I checked the vertical versus horizontal scroll, wrap versus no wrapping text, and it seems related to the vertical scroll. If I limit the items in the list so that it does not scroll, it does not lockup. I tried the default and the Vista skin with the same results.

This is a show stopper for me.
