Stop previous/next month showing in view

Hi,

I am using a RadCalendar control in my web page, to allow users to select/deselect non working days. I have it so there are 12 views displayed at once (3 x 4 grid). This means I can get a whole year's worth into one page.

What's quite annoying is that the previous/next months days sometimes appear in one view - which means in some cases the same day is repeated twice on the page, which is rather confusing and causes me trouble when determining if they have 'deselected' a day. Please select attached screenshot.

How can I make it so that each view only contains days for that month?

[Solved] Nested Grid (based on demo code) not working

I tried to recreate this demo: http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/nestedviewtemplate/defaultcs.aspx

I copied the code given at the bottom of the page and made a few changes. I also changed the panel visibility to true since the panel and the items in it (the grid, tabs, panel background image) will not be displayed if the visibility is set to false. I don't know why you set the panel's visibility to false in the code given. Care to enlighten me on this?

However that's not the reason why I create this thread. When I tried to debug, I get this error message:

Could not find control 'Label1' in ControlParameter 'ParentID'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: Could not find control 'Label1' in ControlParameter 'ParentID'.

I'm this close to tearing my hair out trying to debug this. Can you tell me what went wrong?

Here's my code:

Files uploaded in previous postback are still being uploaded

RadAsyncUpload isnt being consistent with the uploaded files. Attimes, it attempts to upload files that were uploaded in a previous upload, and attimes, it uploads the same file 2ce. I'm not sure what I causing the weird behaviour, but I need some help on this. Any suggestions?

It seems like when an upload is complete, the files uploaded are still being stored in the control somehow, so when a user tries to do a new upload, the files previously uploaded attempt to be uploaded again. What do I need to do to clear out already uploded files. I have ensured that the uploaded temporary files in the RadUploadtemp folder are cleaned out.

Thanks,
Akin

Disabled RadNumericTextBox

Before the update to RadControls for .NET 2012.1 215, I was using the following css rule to darken the text when the RadNumericTextBox is disabled: .riDisabled { color: Black !important; }

Since the update, this no longer works for RadNumericTextBox though it still does for RadTextBox. The new rendering places the riDisabled class on the input element which seems to hold the non-rounded value, but this value is not shown when the box is disabled. There is no riDisabled class on the display span, nor is there an riDisabled class on the wrapper span. The display span is now styled using its style attribute.

Even stranger, using the DisabledStyle-CssClass attribute places the specified class on the input rather than on the display span or the wrapper span. Not sure how this could be useful.

This does not make sense to me. Am I missing something obvious or is this an oversight that will be addressed in a later release?

Thanks for your help.

Chris

Nested forms issue

I am using ASP.NET MVC2 and RadEditor.
I am having a view based on Master page. This view contains a form generated using Html.BeginForm().
Please check 1.png. This view contains several sections having partial views. One of them is Style view (2.png)
The style view contains RadEditor in another partial view (2.png).
You may check the code in 3-6.png. Image 6 shows that i have to use <form> tag to show up the editor, but if remove the <form> tag editor is not shown up (7.png)

The major problem here is if i have use the <form> tag the editor is shown but because of nested forms the data after Style section is not submitted, while if i remove the <form> tag the editor is not shown up but entire data is submitted.

Can you please provide a solution on this.

Javascript Error Thrown After Using Transfer Buttons

I have two RadListBoxes that are contained in a RadTabStrip. When I use the transfer buttons to move items from List1 to List2 and then click on a different tab, it throws me an error:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Any ideas what index field it's talking about?

Also, occasionally when I click on the Tab that contains the two RadListBoxes, they randomly disappear. The items in both lists are still visible but they just overlap each other on the left side of the page.

Thanks in advance!
