Situation:

I have multiple-paged Grid control on the page. It showing all positions in cathegory that user selected.

User can search items via search-engine and it shows elements as a list.

When user clicks on element in search-list, I need to refresh Grid and load all elements from cathegory clicked element belongs to.

Also I need to select this element in Grid and there is the problem: I can not find it in Grid.Items collection if this element not on current page.

Do anybody knows how to get all items ( but not only items from currently selected page ) or may be I doing something worng and there is another way should be used?

I have a small grid with just two columns, Id and User. I have changed the grid's look and feel so that the Add can be done through a seperate button and it works. The grid has two editcolumns Edit and Delete. Delete works fine too. Clicking the edit button brings up the inplace edit boxes, but they are blank. Why am I missing those values? Here is my code for the grid definition and teh code behind for it.

The datasource is a datatable with three columns Id, User and Type.

I'm in the process of evaluating Telerik and have encountered some difficulty integrating with the Microsoft MVC framework. Is there any list of know issues or constraints regarding the integration of Telerik and the MVC framework? It would be a great help in determining where we will need to look for a workaround or custom code. An example of a limitations I've come across are exporting data in a grid to an Excel spreadsheet or using Ajax.ActionLink() to render Ajax enabled links in the table header for partial page refresh on sorting a column.

Your comments and feedback will be appreciated.

Thank you, Brian

 

Hi

I have a simple login form inside a radajaxpanel, plus a separate button and a loading panel.
These are all within another main radajax panel which declares the loading panel.
On button click, the sub to check the database fires and the login proceeds OK.
There is no sign of the loading panel though, at least while it runs on my local machine.

I set the loading panel to run after min delay of 10 and to run for 1000 .   Should this run
or might the event be all over in 10 msecs (but it is the same if delay is 0)?

I tried inserting a 3 second sleep in the button click sub, but it still doesn't show.

Also added an Ajax manager and set button to trigger the main panel and the loading panel
but it didn't change anything

I am puzzled because I have a similar set up working, althought it writes to the database so it takes
a bit longer.

Can you give me some ideas on how to find out why it the loading panel doesn't show. There are no error messages.

Is there an event that i could add some delay to, to check that it will show when running on the production
server?

Thanks

Clive

Hi all,

How to know what version of Telerik has been installed on the PC(including the major and minor build version) ?

Appreciate your assistance.

Thanks

I have the latest release (Q1 2009 SP1).  I have node text editing enabled.  How do I disable this for certain nodes?  It looks like from the examples/articles I looked at there used to be a way to do this, but those methods are no longer available?

I recently changed from using the radgrid contol for .NET2.0 to the 3.5 control.  But now I've noticed that my delete is not working.  When I click the delete button, the record is removed from the grid but the RadGrid1_DeleteCommand method is never called.  But it is called when the RebindGrid button is clicked.  I also have the same problem when delete from a grid where the delete command is defined in the datasource and there is no delete command method in the code behind.  I'm not sure if I'm doing something wrong or if something changed between the 2 versions.  I'm not having any problems with insert or update.
