I have a rad scheduler that shows appointments based on a client click of a rad tree. It works fine until you check the tree and then switch views. I then loose the shown appointment. To see what I mean you can go to here alpha.clickablecommunity.com/calendar.aspx. Expand live music then concerts and check test. If you look at the 30th it shows up. However, change your view either to that week or day and it shows up for a second and then disappears. Can anyone help me out with keeping this visible if it's already checked on the rad tree?

Here is the aspx for my page

Thanks,

I have a problem with a RadUpload while using it in a RadGrid. In Firefox this RadUpload is presented just fine, when i try to use it in Internet Explorer, the RadUpload  is messed up. THis means that it don't adjust the skin to the control and also shows the "browse" option on weird places when i hover the control. I attached 2 printscreens to this message to show the problem.

Beneath i have the code.

I have searched the demo's, FAQ's, and this forum for answers.  How do I get the Value Data Tables to format into Currency?

Hello,

I created a customer control. Based on RadCombobox.

For this control I have to used your workaround http://www.telerik.com/help/aspnet-ajax/back-button-combo-selected-value.html

I add a HiddenControl to my customer class.

Additional I added a js script with GetScriptDescriptors and GetScriptReferences
to implement the js workaround logic.

But it doesn't work.

I add the js on this way:

protected override IEnumerable<ScriptDescriptor> GetScriptDescriptors()

{

var desc = base.GetScriptDescriptors().Single() as ScriptControlDescriptor;

desc.Type = "MyCombobox";

desc.AddProperty("HiddenFieldId", this.hiddenValueField.ClientID);

//Note: If I use here AddElementProperty the property in js will be null

yield return desc;

}

protected override IEnumerable<ScriptReference> GetScriptReferences()

{

return base.GetScriptReferences().Concat(this.GetMyScriptReferences());

}

MyCombobox.js

...

OnLoad:

function() {

this.add_selectedIndexChanged(this._selectItemHandler);

var savedValue = $get(this._hiddenFieldId).value;

if (savedValue != "" && this.findItemByValue(savedValue)) {

this.findItemByValue(savedValue).select();

}

},

...

 

 

In OnLoad this._hiddenFieldId has the correct id, but $get or $find returns NULL.

What is wrong? Have I implement the methods GetScriptDescriptors() and GetScriptReferences() on the right way?

Thanks for support

I am having a few issues and am trying to figure out how to overcome them.  My first issue is a drop down in my edit form.  I am setting the selected value equal to the value from my data source.  However on insert their is not value so I do I handle the null situation?

Second In my entity data source control I have 2 other enitites I am including, once again though on insert, I receive errors when databinding my controls in the edit form template to any of the included entities.  Again I am unsure how to get past this.  I imagine the fix for my first problem will solve this one.

Finally I am unsure how to link the buttons in my edit form template to the proper events in the entity data source control for crud operations.  Thanks!

Hi - I had a problem making the RadAjaxLoadingPanel appear whenever I did a postback. I finally found the solutin and thought I'd share it here.

IE8, return generates 2 lines.  This wasn't a problem with 2009.3.1102.35.     I needed the newer version of the DLL to fix the problem with the Combobox issue.

What version of DLL is this running?
http://demos.telerik.com/aspnet-ajax/editor/examples/editorastextbox/defaultcs.aspx

Shift-Enter generates 1 line.   If I use the margin:0px below, on the screen it's fine, but it still retained <p> in the code, which in my HTML email it displays with additional lines.   NewLineBr=true/false doesn't make a difference.
Removing OnClientLoadRadEditor() doesn't make a difference.

{  
    margin:0px;

I'm new with RadScheduler. Can anyone tell me how to do nested quarter views? I need to first group by year, and then by quarter. Thank you in advance for your help!

Hi

I have 2 radmenus on a page and I use the ajaxmanagere to ajaxify the click events as per normal

the mark up looks something like this , obviously with the specific panels to open referenced inside the <UpdatedControls> tag


The loading panel does not seem to want to fire for Menu 2 and I have lost some functionality in Menu 1 too, Is this because the AjaxControlID's have the same name ? and if so how do I distinguish between them

Can anyone tell me how to do nested resources in RadScheduler? I need to first group the resoource by building name, and then by meeting room. Thank you in advance!
