I have two RadComboBox controls in my RadGrid CommandItemTemplate.  When I rebind the grid in the _TextChanged events of these two comboboxes (used to filter the grid), I get postback errors.  This didn't happen prior to the service pack.  Any thoughts?

Thanks,

Hi

I am using Telerik controls 2008 Q2 (will get SP1 in a few days).

We are creating a rather large website and we are minimising the use of UpdatePanels to increase the user experience. This does mean a lot of Javascript and the use of PageMethods / WebServices but it's worth it.

The RadControls client side functionality with the new client-side grid databinding are making our pages extremely fast.

Some of our pages are huge so we only render a portion of the screen and then use a load-on-demand approach to minimise the initial load time.

However in some our instances load-on-demand can request a lot of HTML (sometimes over 100Kb!).

So I have 2 questions:

1. I realise that Telerik controls can't be created client-side, but are there plans for this to be implemented? (I don't know what I'm asking here as I'm not a control developer). Creating such controls in Javascript would certainly reduce the need for UpdatePanels.

Or...

2. I understand that being web controls I just can't use a PageMethod approach to get HTML as Javascript, etc. is also required. But can such an approach work? Or is the UpdatePanel the only way to go?

I suppose it never hurts to ask.


Kind regards

hi,

I want to update IFrame content after particular interval.
I have seen your demo example which updates a grid after particular interval but when I set the update control to iFrame, browser looks like it is postbacking the page.

Is there any solution which replaces post back to ajaxrequest/update.

Thanks,

hi. looked at the sample page here . http://demos.telerik.com/aspnet/prometheus/Window/Examples/BrowserDialogBoxes/DefaultVB.aspx .
don't get it. well... I get it just not in how to use it for my issue.
Simple issue. confirm record deletion from a formview.
the setup.
container.aspx has radwindowmanager and radajaxmanager (controls the radtabstrip and radmultipage). Rad multipage has my ascx grid/form pages
within myform.ascx I have a formview / editItemTemplate.

The issue.
the radconfirm raises the confrm dialoge, however, clicking OK does not result in record deletion. If I remove return false;  it deletes the record regardless of the button clicked.
What am i doing wrong ? Do I need to trap the confirmation back in JS? And if so, how do i tell page to proceed with the deletion? Sorry if this is a stupid question.. I just don't understand how to get this to work.

Hi,

I guess I have some understanding issue concerning the RadGrids SubObject databinding. I have bound a RadGrid to a LinqDataSource which works perfectly out of the box. One of the object members is a relationship which is represented by a foreign key on the db. Now I want to bind the corresponding colum of the RadGrid to the "Name" field of the object which is referenced via the relationship.
If I understand the documentation correctly, I have to do this via the GridBoundColumn's DataField attribute. There I put "Product.ProductName" but the column remains empty.

What could be my mistake?

Best regards,
Robert

Dear Sir,

I use isEmpty (client-side script) to check is input box empty or not...
However, if I type a invalid value (therefore, input box is not empty anymore), the isEmpty still returns true...

              if(!dpDelivery1.isEmpty() && date1 == null)
              {
                    alert("Invalid Input");
                    return false;
              }


For my suggestion, Telerik could provide a isError function for validating input value.  That's be more easier.

Team,
            I am developing a page which needs to refreshed after some moments.
Scenario:
Page will have a grid with some 10 Steps and column 'Active'(by default it will be no) and a asp:button. After clicking the button i am executing a procedure in database it may take 5 - 10 min. This procedure executes step by step say step 1,step2 .......step10. 

Now i want to show the user about the step status, just like a installer.
 

Quick help in this regard would be appreciated


Thanks

Hi

I am using RadGrid 2008 Q2.

I find that the client-side databind of the grid is extremely well done. We are now doing far less postbacks to the server and because we do everything we possibly can on the client we are gaining a far richer user experience.

I have 3 questions:

1. I have noticed that if we start with a blank grid it defaults to loading 10 empty rows. This is far more when using a hierarchy as it seems to load an extra 5 rows for each master row. As such it can start with 50 rows!

Is there a reason for this?

Presently on the server when the page loads I bind to a dummy class object of just 1 row.

This way I have reduced the HTML response from 117Kb down to 50Kb.

Are there any implications to this? I haven't noticed anything break by taking this approach.


2. When adding items to the grid it all works nicely.. until I add an item past the initial HTML markup. E.g If I start with the default 10 rows, the 11th row is shifted to the right and the data is in all the wrong columns.

This happens as it seems the first 10 rows respect hidden (not invisible) columns but the 11th row onwards does not (in fact it will show the hidden columns).

A further consequence of this is that the hierarchy column (+/-) no longer shows.

How can I avoid this?


3. I couldn't find any examples for a hierarchal grid. At the moment I bind my detail grid in the RowDataBound() client event as it seems that the detail view doesn't automatically fire like it does on the server.

E.g.
if(e.get_item().get_owner().get_name() === 'VenueDetails') //MasterView
{
 var tableView = sender.get_detailTables()[e.get_item()._itemIndexHierarchical];

 // Bind detail to grid
 tableView.set_dataSource(e.get_dataItem().EventMisc);
 tableView.dataBind();
}

Is this the correct approach? I'm not comfortable with it as I am using a protected member: _itemIndexHierarchial.

Kind regards
