Problem when I add Rad Ajax Panel

Hello all :)

I add an ajax loading panel and ajax panel to my page, but when I run the page I got this message

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

Combobox gives javascript error while adding HTML or XML tag in it.

Hi Team,
I am facing one issue, While adding any HTML or XML tag in my telerik:RadComboBox
it is giving a javascript error as :

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500

This error is only coming when I put < with some alphabets ex: "<aa","<a" or "<TEST>".
Even it is working proper when I put "aa>" or "<>".

I have followed the solution suggested as in thread:
http://www.telerik.com/community/forums/aspnet/combobox/combobox-crashes-opon-entering-html-tags.aspx

As my error is coming on Client side so I have used htmlEncode method also as:

$('<div/>').text(value).html();

Still I am facing the same issue.
Please give suggestion to resolve this issue.

disabling editor from serverside and set class

There were a few things i was trying to do.
First off, i have the following 1 line of code:

_bleh

.MemoEditor memoEditor = new _bleh.MemoEditor(__stuff__); //modified for privacy of company.

which calls the RadEditor.

I was looking through the code to see 1) where i can assign the class in the server side code as well as 2) Where do I, from the codebehind, set enabled = false?

I was looking for some sort of attribute setter and getter for the constructed html, but i didnt see anything from my first glance.

OnClientCommandExecuting Error

I added a custom drop down to my editor. I created the OnClientCommandExecuting function to handle what happens when someone selects an item in the drop down.



The problem is the event fires when I press enter inside the editor, which is causing the following code to throw an error:




function OnClientCommandExecuting(editor, args) {
 
        var name = args.get_commandName();
        var val = args.get_value();
 
        var info = val.split("::");
 
    }



Error:




val is undefined

Future development

First of all congratulation on the new 2011 Q2 release and introduction on new ImageEditor control. I understand this is just the beginning and I would like to know what is the roadmap for this control? Do we see new features such as image annotation coming soon?

Does this control support custom toolbar, as seen in RadEditor?

Grid, using Dataset with Insert/Update/Delete Issues

Hello All,

I am recently working on a problem where i need to create an area for customer to entering employees information, to start off there will be no information contained within the table. Then using the setup down below and some back end C# i want to populate the GridEditForm that also doesn't want to popup. I have been looking for some information on how to program in the back end or possibly java script, though i don't see this as a client side issue. this as i wish i could use an sql data source but to limit access and security we use web services where i get information in a data set which i want to manipulate then send it only once it has been completed.

There's pretty much no C# back end as of now, just a garbled mess of failed tests

And for posterity a brief snippet of C# of my data set

C#

protected void createDummyRow()

{

employeeDummyRow = new DataSet();

DataTable dummyTable = employeeDummyRow.Tables.Add();

dummyTable.Columns.Add("Employee", typeof(String));

dummyTable.Columns.Add("CraftDescription", typeof(String));

dummyTable.Columns.Add("JobClassDescription", typeof(String));

dummyTable.Columns.Add("HoursWorked", typeof(Decimal));

dummyTable.Columns.Add("RateOfPay", typeof(Decimal));

dummyTable.Rows.Add("","","",1,1);

}

protected void Page_UnLoad(object sender, EventArgs e)

{

if (dsEmployees == null)

{

Session["dsEmployees"] = grdEmployee.DataSource;

}

else

{

Session["dsEmployees"] = dsLEAPEmployees;

}

public void grdEmployee_OnNeedDataSource(Object sender, EventArgs e)

{

if (grdEmployee.DataSourceIsAssigned == true)

{

grdEmployee.DataSource = grdEmployee.DataSource;

}

else

{

grdEmployee.DataSource = employeeDummyRow.Tables[0].DefaultView;

}

I hope someone can suggest possibly a mind blowingly easy way to merge data set and caching of the data with the current structure!

Thanks!

timeslotcreated

hi
i am completely stuck at a point while scheduling an appointment b/w doctor and a patient.
i want to know what does timeslotcreated eventArgs e mean in timeslot created event .
I have written my code as follows :

if (DateTime.Compare(e.TimeSlot.Start, Convert.ToDateTime("2012-06-06 08:30:00.000")) == 0 && DateTime.Compare(e.TimeSlot.End, Convert.ToDateTime("2012-06-06 08:45:00.000")) == 0)
{
e.TimeSlot.CssClass = "rsCategoryGreen";
}
if (DateTime.Compare(e.TimeSlot.Start, Convert.ToDateTime("2012-06-06 08:45:00.000")) == 0 && DateTime.Compare(e.TimeSlot.End, Convert.ToDateTime("2012-06-06 09:00:00.000")) == 0)
{
e.TimeSlot.CssClass = "rsCategoryGreen";
}

The whole slot of 08:30 - 09:00 is getting green. and when i remove upper IF then nothing happens in output.
please solve it or give an alternate solution to do this?

Still i am waiting for someone's reply. I want to clear my problem now..
I have an appointment of 2 hours and i want to customize it in different timespan like one of half an hour and second of one and half hour with different custom. So which event schould i use?
