[Solved] DatePicker.Clear() doesn't seem to work

Hi,

I'm using the RadDatePicker object for its client side functionality but not interested in the server side. I have it on a page where ViewState is switched off, being created dynamically inside a repeater.

Once a form is submitted successfully, I want the entire form cleared so that another new record can be added. However I am hitting a problem with DatePicker, DateTimePicker, and TimePicker that I cannot seem to resolve.

Here is the code I am using to create the object (there is a placeholder inside a Repeater item and this is being called at Repeater_OnItemDataBound)

private void DoDatePicker(FormColumn column, PlaceHolder ph)
       {
           var picker = new RadDatePicker {ID = column.FieldName};

           ph.Controls.AddAt(0, picker);
           picker.Clear();
       }

I've tried putting the picker.Clear() before and after the AddAt statement but regardless of what I set, the date from the previous form is still being displayed. I've also tried picker.SelectedDate = null, that didn't work either.

What do I need to do to clear the previous date, short of hacking into HttpContext.Current.Request and deleting all the form values connected to the Date/TimePicker?

Thanks for any assistance.

DataTextField mapped to two different DataFieldParentIDs

Hi,

Is it possible to map a single DataTextField to multiple DataFieldParentIDs? I have a MenuItems table that contains MenuItems and a MenuToMenuItemsExtension table which maps MenuItemIDs to ParentItemIds. MenuItems that are the same (same text, same link, etc.) can be mapped to multiple parents, ending the need to duplicate MenuItems in the MenuItems table.

Thanks, -Scott

[Solved] Changing cursor when mouse over

Hello,

can someone tell me how to Change the cursor when the mouse cursor is on an item? In my application it is possible to click on an item. Unfortunately I cant't figure out how to change the cursor from default do pointer when the Mouse gets over. If its possible I'd like to have the change on the image and the text below as well. Also, I'd like to change something in my CSS or my application instead of changing something in the telerik css files.

Thanks in advance

[Solved] Centering Radgrid on RadDock

Hi, I have a radgrid inside a raddock which I am trying to center but it is always left aligned. I tried with the horizontal-align property set to "center" but it wont work. Also, everything inside the contenttemplate of the raddock is inside a division which has the text-align property set to centered. What else can I do to center my grid?? Here is the code if you need it...

SelectedIndex

Hi,

I am observing some unexpected behavior when using RadComboBox - I set SelectedIndex to some value, say 2, in code behind, but then if I type something in the input and trigger a postback (say, via an asp:Button), the selected item is not changed , and the Text property doesn't get updated - everything stays the same.

I would expect that every time I set SelectedIndex to some item index, the Text and input contents get updated, no matter what is there already.

Is this a bug?

Thanks,

Tom

FileBrowserContentProvider File Problems

Hi,

I am implemting a custom FileBrowserContentProvider for the ImageManager of the RadEditor. The purpose of this customer provider is to ensure the images inserted in the content of RadEditor can only we read if the user has logged on to the website and has sufficiant rights. Having that wish just a browsable virutal directory is not an option since the users are also located outside the domain.

During Implementation I found a very nasty problem which I can't solve.. I' am implemting the Telerik.Web.UI.Widgets.FileBrowserContentProvider interface. My problem is.. I build up all the stuff needed (see code below). But when using the ImageManager the tree on the left side is displayed perfectly. The content of the folders is also visible. But when clicking on a image in the content view of the folder only the content of the top image is displayed.

For example I have the folder :

Windows Images
    - Koala.jpg
    - Desert.jpg
    - Flower.jpg

When I click on Koala and Insert, the Koala picture is shown, and inserted in the RadEditor. When I click on Desert, the Koala picture is shown and inserted in the RadEditor. When I click on Flower the Koala picture is shown and inserted.

What is going on here? The generated urls for the Images are 100% correct and shown correctly when I invoke the url of the image directly. When I consult the debugger the content of the FIleItem aray is also correct. Please Help me!

Martijn,

PS. Keep up the good work!
