Hello,
I was trying to copy this scenario: http://demos.telerik.com/aspnet-ajax/htmlchart/examples/functionality/datanavigation/defaultcs.aspx
in my project. I copied RadHtmlChart block of code with datasource and file as well. 

I found that all Chart turns white without nothing on it and i Get JS error:
"Uncaught TypeError: Cannot read property 'length' of undefined Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=ctl00_rsm_TSM&compress=1&_TSM_CombinedScripts_=%3b…:16929"

Then i did comment on Navigator Series code. and after that top chart was showed proper. 
After that i turned back to 2014.1.403.40 build where everything is ok. 

Can you help me by telling what cause that error?

Hi,

I am creating a chart with two ColumnSeries with X-Axis containing Date and Y-Axis containing Item count. Now I want to create a stacked chart for the two series. Below is the program i have got. When I ran this, I am getting attached Chart which has X-Axis items not overlapping. For Series2, X-Axis items are again added. Even though, I am checking for the duplicates, it is adding the x-axis item. 

I cannot use Date as X-Axis type because, it only supports Databound objects. Is there a way to achieve my desired behavior without X-Axis values overlapping?

Is there any easy way to add some additional controls on the pager without using a template and (thereby) redefine the complete pager?

Today I have a DropDown where the user can select to what depth the TreeList should be expanded. It would be very nice if I in some way could have this dropDown located on the Pager instead of outside of the TreeList control, but I don't want to redefine the complete Pager with all it's current controls, just add one extra on the existing line. I've attached a screen shot indication what I want to do.

What is the simplest way of doing this?

Below is my aspx code:


Update: Tested it out on Google Chrome, IE8, and IE7 and the validation is working just fine. But it's not in IE9.

Hi,

As you know it is mandatory to set the ExportOnlyData property to true when using ExcelML format. Thanks to that GridCheckBoxColumn is exported as TRUE/FALSE in Excel spreadsheet. How can we have that column exported as checkbox as in old HTML-Based Excel Format?

Dears,
I have an issue using radDatePicker on chrome, as when I select 1st Aug 2014, it sets the selected date to 1st Sep 2014 ?
to reproduce go to
http://demos.telerik.com/aspnet-ajax/calendar/examples/datepicker/custompopup/defaultcs.aspx
and try to select 1/Aug/2014

I am wondering how I would go about turning off the automatic orientation for the combobox. I am running into an issue where the dropdown is going up and underneath my menu.

Hi,

I am trying to update a read-only GridDateTimeColumn field in a Rad Grid while the item is being edited. The computation to do the update is to calculate the calendar date based off the Julian date in a RadNumeric TextBox. I am able to get the two controls client ID's by using the following code server-side on the Item Created event:

RadNumericTextBox rnumtxt1 = item.FindControl("gtbJulianDate") as RadNumericTextBox;
RadDatePicker picker = (RadDatePicker)item["GroundDate"].Controls[0] as RadDatePicker;

rnumtxt1.Attributes.Add("onBlur", "return updateGround('" + rnumtxt1.ClientID + "','" + picker.ClientID + "')");

The javascript function finds the RadNumeric TextBox just fine and can perform the computation, but when I set the picker field on the client-side, it always ends up being null. I use the following code to set the variables:

var julianTxtBox = $find(txt1);    
var groundDate = $find(txt2);

Can you please help by letting me know why that is not working or if there are any other ways to access that field and set it on the client?

Thanks,

Joe

I want to change some behaviour in the the expand column of a RadGrid. I don't seem to have any control over the column even though I am adding code that seems like it should provide control. For instance I add this line in my .aspx page :

<ExpandCollapseColumn Visible="false"></ExpandCollapseColumn>
It doesn't matter if I choose True or False, the column is still there. 
I change the button type or any of the options I get in intellisense but the grid renders the same. 
I want to add a header to the column for my users since they don't seem to comprehend what the arrow is for 
without instructions. I'm posting what I think is the relevant markup in case I did something wrong here. 
Thanks for any help.
