Handling Resources with a custom Appointment Provider

Implement a custom appointment provider. Is there a mechanism for the provider to get the resources once and then keep them in the scheduler for duration of the page? I would expect the provider to supply the resources and the scheduler to keep them until they are explicitly changed (ie. for another view). But in my case, the provider has to get the resources from the database every time it is accessed (ie. getting appoitments, adding appointment)

I have overridden GetResources(ISchedulerInfo schedulerInfo) to return the resources available to the scheduler; however, it doesn't seem right to me that it queries the backend for the resource definitions on every postback.

If I set the resources programmatically the scheduler seems to maintain the resources on postbacks. For example...

if (!Page.IsPostBack)

{

ResourceType providers = new ResourceType("Providers");

providers.DataSource = ScheduleAdapter.GetViewResources(defaultView.ResourceViewID);

providers.KeyField = "ResourceID";

providers.TextField = "Resource";

providers.ForeignKeyField = "ResourceID";

RadScheduler1.ResourceTypes.Add(providers);

}

What am I missing with the implementation of a custom provider? How do you get the provider to supply the scheduler with its Resource collection just once.

Thanks.

radgrid export to excel not accepting double white space

Hi,

I have a radgrid in which I'm binding the data. For instance I have the column "SER" in the grid. The value of "SER" in the grid is
"NG 101101". The length is fixed i.e 10.

When i export the above data using export to excel, the radgrid exports the above data to "NG 101101". It removes one space. I don't want the excel to remove the space. I need to maintain the data as such.

Could you please help me achieve what I want.

Thanks,
Raji

html formatting

First div tag gets reformatted on save. 



Original Code:

<

div class="main-block comparison" id=

"comparison">

<div class="main-frame">

<div class="left-col">

<h2>Product Comparison</h2>

<p>Quisque commodo hendrerit lorem quis egestas. Maecenas quis tortor arcu. </p>

</div>

<div class="right-col">

<div class="image-holder"> <img src="_themes/v2/images/img.png" alt="" /></div>

<a href="#" class="launch-btn"><span>Click to Launch Comparison Tool</span></a>

</div>

</div

>



And it gets reformatted as:

<div class="main-block"> 



I tried adding StripFormattingOptions="noneSupressCleanMessage" and ConvertToXhtml="false" 

to see if that made a difference.

RadPageView and DefaultButton

Hello,

I am currently trying to have a LinkButton be the default button in my application. While on RadPageView1 I would like the LinkButton's OnClick event be fired when the Enter key is pressed. If the RadPageView had a property like DefaultButton this would be easy. If it does have this property, I can't find it. If it doesn't have it, I think that it would be a good feature to add to the RadPageView.

Thanks,
Casey

Filtering on a list of values

Hi all!

I'm currently prototyping a 'Telerik' version of a suite of tools I created for the administration of our application's database. It's ticking all the boxes as far as interactivity on the frontend goes and I want to show that it's a viable option for replacing some of our older vanilla ASP.NET 2.0 tools.

One of the tools in question allows a user to copy a list of values (in some instances GUIDs, others just simple integers) in to a textbox (1 value per line) and send that to the Datasource for filtering on. This is then displayed in a vanilla ASP.NET GridView.

For example, a user may fill in the filter box like this:

IDs
====
1156
785636
72889

...and the system will return entities with those IDs.

I run the contents of those various textboxes through a splitter and sanitizer (essentially a set of RegExs to ensure there's no errors or injection attempts) before submission, but the only way I've been able to get that list to the DB is by using a String.Replace on the SELECT code in the Datasource before it refreshes, which puts the list of values into an IN clause. I hate this because it feels like a hack and stops me using SPROCs for my Datasource, but it does work.

I've read in one Google result that a nice way of doing this is to somehow convert the Textbox contents into a CSV or XML file and submit it that way, but it doesn't seem to help with the overall complexity of the code and it doesn't make use of anything that Telerik provides over and above vanilla ASP.NET.

Does anybody know how I might go about doing this in a more 'proper' fashion using any functionality that Telerik provides? Am I best off trying to perform the same hack, or have any of you managed to make such a filter in a smoother way?
