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?

Dynamically Selecting Rows from LinqDatasource

Folks, Using ASP.Net Ajax Q1 2012 with VS 2010.

I am using below link as a prototype.

http://demos.telerik.com/aspnet-ajax/grid/examples/performance/linq/defaultcs.aspx

My question's are:

1) I would like to have an option just to show 1st 2000 rows or all rows in the Form based on user input. I will create a Text Box where users will enter # of rows to Show in Radgrid. if Textbox is null then show all rows.
.
2) Possible to select rows (may be 2000 or all rows) from mutiple tables (i.e. Products and Category) based on a certain Catergory Description? Ex: I will have a Text Box in the form for users to enter Category description and based on that Text Box value, show only Radgrid rows that meets the criteria. But insert/update/deletions will be limitted to Products Table only not in Category Table.

The soutions I am looking from LINQ to SQL, not SQL.

Thanks
