RadDatePicker error.

Hi,

In my applicationn i had a RadDatePicker with the following syntax:

<telerik:RadDatePicker ID="txtDate" Runat="server" Skin="Sunset"

FocusedDate="" MinDate="01/01/2006" ShowPopupOnFocus="True" TabIndex="20"

Width="155px" MaxDate="01/01/2020">

<Calendar UseRowHeadersAsSelectors="False" UseColumnHeadersAsSelectors="False"

ViewSelectorText="x" Skin="Sunset"></Calendar>

<DatePopupButton ImageUrl="" HoverImageUrl="" TabIndex="20"></DatePopupButton>

<DateInput DisplayDateFormat="dd/MM/yyyy" DateFormat="MM/dd/yyyy" TabIndex="20"></DateInput>

</telerik:RadDatePicker>

My requirement is i need to bind 10 days back date from today's date to RadDatePicker with the following syntax:

txtDate.SelectedDate =DateTime.Now.Date.AddDays(-10);

Here i am getting the following error:

Value of '7/2/2011 12:00:00 AM' is not valid for 'SelectedDate'. 'SelectedDate' should be between 'MinDate' and 'MaxDate'.
Parameter name: SelectedDate

Any one please suggest me the solution for this?

Thanks in advance...

Question regarding RadCompression

Hello,

I am attempting to integrate Rad Controls for AJAX with an MVC View-Page. An issue I had early on has reared its head again during development. If I modify the mark-up for my page such that it is in an erroneous state, and then try and run the page, I would expect to see something akin to "Server Error - Error Message Here." Unfortunately, my error messages are becoming compressed and never decompressed. This leads to garbage characters being rendered on the screen instead of a helpful error message.

The first time I encountered this issue it was code in our solution --

public override void OnActionExecuting(ActionExecutingContext context)

{

//This compression filter eats server errors. I'd like to see them during debugging.

if (!HttpContext.Current.IsDebuggingEnabled)

{

HttpRequestBase request = context.HttpContext.Request;

string acceptEncoding = request.Headers["Accept-Encoding"];

if (string.IsNullOrEmpty(acceptEncoding))

return;

acceptEncoding = acceptEncoding.ToUpperInvariant();

HttpResponseBase response = context.HttpContext.Response;

if (acceptEncoding.Contains("GZIP"))

{

response.AppendHeader("Content-encoding", "gzip");

response.Filter = new GZipStream(response.Filter, CompressionMode.Compress);

}

else if (acceptEncoding.Contains("DEFLATE"))

{

response.AppendHeader("Content-encoding", "deflate");

response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress);

}

After adding in the check for debugging I began seeing my helpful error messages again.

Now, I recently went into my web.config and added the lines necessary to enable RadCompression. My issue has arisen once again -- I see garbage characters instead of error messages.

Is there something I should be checking elsewhere in my code, the data type of the stream or something, to account for errors + RadCompression?

Kind regards,

Sean

Advanced Edit or Insert Form Slow load times

Hello,

How do I improve the load times of the Advanced Edit/Insert forms. I really need the Recurrance control but the load time is terrible. With a basic setup and no appointments on the Scheduler it still takes 5-6 seconds to load. I am also seeing the same response time on your demo pages. I also get the same results in my Dev environment as well as Production regardless of the form being modal or not or if debugging is on or off. I have read the posts on how to improve performance but they mostly relate to improving loading of appointments. I am seeing this response time with no appointments.There has got to be a way to make this faster?? Below is my basic setup. I am using 2010.3.1317.40 release. Thank you!

</FilterMenu>

</telerik:RadGrid>

But it doesn't work. Even if I don't put any date or text in my controls, the ItemCommand event is thrown. The worst is that I think it worked last week... What have i wrong ?

Style Issue within Sharepoint

Hy,

It seems that there is a style issue (maybe it has something to do with the one of the Radtoolbar). While the color of the text for "Design", "HTML", "Preview" is shown correctly under Firefox, it is kind of purple when showing the page with Internet Explorer (IE 9). I´ve tested the Skins Windows7 and Vista.

I am using the the Controls within a Webpart in an Sharepoint 2010 Environment.

Could you test it on your side?

Telerik Radgrid: Image button not working when enableviewstate=false

Hi

I have a radgrid of which I have made the EnableViewstate=false and added the OnNeedDatasource event. One column of the grid has delete buttons which is image button. After disabling the view state the delete button is not working properly. The command argument and command name are not getting set properly. When the delete button is clicked its "OnCommand" event is fired but the command argument sets as empty there.

But it is set properly in the Onitemdatabound event. Under the same changes if i use linkbutton instead, it works fine. Please help.

Regards
Shirish
