We have a page with a number of DatePickers and a submit button.

The DatePickers must contain a valid date, or they can be blank.

When a user enters an invalid date into a DatePicker field, and then switches focus to another field the DatePicker displays its contents in red, and adds a little "!" icon.

If the user clicks on the submit button while a DatePicker fields contains an invalid date, how do I tell in the code-behind that a DatePicker field contains invalid data?  In this case, SelectedDate is null, but SelectedDate is null if the field is blank, so that's no help.

I need to be able to distinguish between whether a DateField is empty or whether it contains an invalid value, from the server side, and I can see no way of doing so.

Hi, I've tried to set a static position on my fastnavigationpopu when we click on title of the calendar inside the RadDatePicker and i also add an other function to show the calendar over the dateInput when there's not enough space on bottom of the screen. But the thing is that when the calendar is showing over the dateInput the fastnavigationpopup show where he should be when the calendar is under the dateInput.

Is there anyway to set the position on click of the calendarTitle? or simply get the fastnavigationpopup

Here,s the javascript i used to implement both function:

FastNavigationPopup: (OnLoad / OnCalendarViewChange - Calendar)

For the calendarPopup (OnClick - DatePopupButton)


Thanks

When a large radgrid was printed from a web page, the1st printout page displayed the gridlines properly.   However, starting from 2nd printout page, the gridline disappears.  The grid used radgrid.dll v.5.120 (1.1 framework).  The skin was "Classic".   Any work around suggested?  Thanks!

One additional note: By using your radgrid within 2.0 framework, the 2nd page was printed with gridlines.  However the problematic grid print was in 1.1 framework.  Please help on this.  Thanks.

Hi,
I need to disable the dates outside the current month of the current view.
For example February, then I want to disable 26-31 of January and 1-8 of Mars.
I'm trying with the dayrender method with no success.
(the red background is set so the if-statement is working)

With this code I can still click on all dates! :(
Is it because I have AutoPostBack=true?

I have an issue with the horizontal scrolling. Dragging the scrollbar or clicking the arrow buttons work fine if I don't freeze any columns. The moment I've frozen the first 2 columns the following starts to happen:
- I begin dragging the scrollbar until its center reaches about 1/3 of the grid's width (let's name this position A)but nothing is scrolling yet!
- I continue dragging and for the next approx 50 pixels (the whole grid is 830 pixels wide) all the unfrozen columns scroll at high speed until only the last column is visible (let's call this position B)
- I drag from B all to the right and obviously nothing happens
- I now begin dragging back from the far right towards position B - nothing happens; when I reach back to position A ALL the unfrozen rows JUMP in their original position like they should look when the scroll bar is all the way to the left
- I drag from A all the way to the left and obviously nothing happens

What I think that should happen is that the scrolling should be happening smoother, on all the width of the dragging, not only on those 50 pixels. And when you drag back from right to left the columns should scroll one at the time, not jump back at once.

I have a master page set up with a RadAjaxManager, some controls, and a content placeholder.  I have wired up a few buttons to a RadTreeView that exists on the master page, and ajax updates are occurring as expected.  I have also used RadAjaxManagerProxy to successfully ajax-enable a grid that resides in the content page.

What I have not been able to do is configure the content page so that I can trigger an update to the treeview on the master page.  Here's what I've done so far:

1. I have exposed a public method on the master page called BuildHierarchy() which populates the treeview.
2. I have a button in the content page that calls the BuildHierarchy() method after changing some data.
3. I have programmatically added the ajax settings that I thought would allow the AjaxManager to allow that update.

Below is the key piece code I've used to try to set up the scenario described above.  The buttonMakeDemo control is a button which I need to update the RadGrid within the content page and the RadTreeView in the master page.

First, the relevant ajax code in my ASPX page.  I'm allowing the grid to be ajax-enabled for sorting, and I'm allowing the button to update the grid:


Next, the relevant codebehind in the content page.  You can see that I've also tried adding the settings to the RadAjaxManagerProxy's AjaxSettings, but that doesn't work either.


In case it matters, here's the codebehind for the button click event.  "ThreePaneMaster" is the class name of the master page in question.  Don't worry about the argument passed to that BuildHierarchy method -- it's a business object accessible on the page.


Any ideas what I might be doing wrong?  The ajax-enabled controls work so long as they're all either in the master or in the content, but not if one's in the content and one's in the master.

Thanks,
Josh

Is there an easy way to add a beginning and ending image to a horizontal menu?  I would like to have a curved image on both ends to smooth the look of the menu.  My menu is inside of a table <td> element.

I tried:
<img src=...>
<telerik:radMenu ...>
<img src=...>

but when opened in IE I see the two images on one line, followed by the menu on a separate line immediately below it.

Any help will be very much appreciated!

Hi. am working with tabStrip, and i want to make different content in different tabs.
Everything is okay, but i can not click on the tab when am starting the form, so i can see only the content of the first tab, a can not switch to another.

Please for Help.

I've created a custom skin, and I'm currently trying to get the list item's of the submenu to align to the center of their parent ul. However, when I put a border around the parent ul, I see that it is 0 pixels tall, and does not wrap around it's li's. I was wondering, why is it doing this? It is preventing me from simply putting text-align:center on the ul element.

Any help would be greatly appreciated.
