Hi,

We are using Rad Controls and Rad Grid Extensively in our project.  Right now i am working on the optimization of the Rad Controls. I want to know few scenario what we had implemented in our application. My application Structure.
1) Master Page is header part contains the Rad Menu. On Menu Click Navigates to the respective content page.
2) All our content pages contains the RadGrid
3) We are using WebUserControl for the RadGrid EditForm.
Ref : http://test.aptisys.com/UOMSetup.aspx

Please answer my below queries based on the our above mentioned application UI Structure.
1)  We are using IBindableControl interface and bind the user control form elements that in turn automatically bind to the rad grid. (We are worried does it cause any performance issues? If the binding is automatic in this manner to the Rad Grid does it takes more memory or load time than manually binding using need datasource ?
2) Which one is more faster in terms of loading the data in the grid with the webusercontrol edit form with add, edit, update and delete feature? Is it Autobinding using Ibindable interface or Using NeedDatasource?  Which is more controllable?
3) If we set the view state as false in the grid and implemented the autobinding using IBindableControl Interface. Is to programatically able to rebind the data on update?
I have seen the below code in the support resource.

4) How do you get the Rad Grid Reference if it is the WebUserControl? For example when we click the save button we need to make the data source null and rebind the update datasource.
5) Is it posssible to implement rebinding of the RadGrid without need datasource if the view state is set to false?
6) If possible can you send some examples how to do it?
7) Is not so even using the need data source how do you get the reference in the of the RadGrid since it is an Web usercontrol that is tied to the rad Grid as Edit Form?
8) Could you please send us some example for both the scenario rebind the data to the RadGrid after update or save if the view state is set to false using WebUsercontrol as edit form?
9) If the view state is set to false in the RadGrid and i am using need datasource? I have seen that Grouping, Filtering feature doesnt work.  What is the workaround for these scenarios? Pls send us some examples.
10)Pls send us the examples handling grouping, filtering for the above scenario, if the View State is set as false?
11) In what scenario i can used the Ibindable interface autobinding and in what scenario i can make use of need Datasource? Pls Advice.
12) In the Heirarchy Grid, Right now we are using the Autobinding, if we go for the manual binding using the needdatasource is it complex to implement all the grouping, filtering scenario using the webusercontrol as edit form?Could you please send some example using the manual binding webusercontrol -Heirarchial RadGrid Examples supporting the Grouping, Filtering, Sorting, etc.
13) We are using the image icon as the view button on each row of the rad Grid, you can see from our url mentioned on top.? Does the image icon in the row cause any performance issue?
14) Using the Tooltip Manager in the RadGrid causes any Performance issue? What are the work around? Please advice with examples.

Thanks & Regards

Hi,
I need to know where call  and ajaxRequest in a particolar scenario:

When i click in ContexMenu of a RadTreeView i open a radwindow that receives some arguments from the RadTreeView .
On the radwindow i have two hiddenfields and a radajaxpanel that contains a formview.
I Get the args on the rad window with this javascript function

function pageLoad() {txtInputIdLinea = document.getElementById('hdfIdLinea');

 

 

 

var currentWindow = GetRadWindow();

 

txtInputIdLinea.value = currentWindow.argument.Idlinea;}

 

 

The datasource of the formview has hdfIdLinea as a parameter.

The problem is that when the radwindow finish "loading" the formview didn't see the value set in hdfIdLinea, so  after setting the value i add an ajax Request like this
$find(

 

"<%= Panel.ClientID %>").ajaxRequest("Update panel");

And It works, but this code run in a loop and i have this exception
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed.

May you help me?. I need to force a postback of the FormView once time after the radwindow is loaded.
thanks._

 

I have a RadGrid that i a sorting by "AdmitDate". This date column could have NULL values and i need to get these rows to display on top of all other RadGrid rows. I was hoping that i could place these rows with NULL values in a group at the top of the Radgrid. Sorting the SqlDataSource in Asc order works, however i need to display the rows with actual dates in Desc order.

I was then looking into populating two SqlDataSource. 1 for the null rows and one for the non-null rows. I was then hoping that the RadGrid could append the two datasources together in the grid. Is this possible?

Any guidance as to how to accomplish this would be great.

Hello Telerik team,

Hi
sorry for bothering, but I've a few problems with the programmatic creation of columns in rad grid.

I start from the scenario that for me it would be perfect because I'd like to understand how far the grid is from it:
- should be possible to create the columns of the grid in the page_load (when IsPostBack == false)
- the dynamic columns should be of type Template
- during the event phase of the page (basically when a user clicks a button) it should be possible to clear the old columns and create new ones.

I've looked to this example
http://demos.telerik.com/aspnet-ajax/grid/examples/programming/groupby/defaultcs.aspx
where you attach columns dynamically on the onload of the page. That works with simple columns, but fails with templated columns.
For precision's sake, I'm using NeedDataSource event, but on postbacks the InstantiateIn method of the templates is not called.
Is there any way to force it on postbacks?
Should I use the simple DataBind approach?

I've also tried creating the columns in the oninit (I underline the fact that I don't like it very much, because OnInit is a very early phase of the control lifecycle. Many informations could not be there for deciding which column instantiate).
I was able to create both simple and template columns, but I had to do one of these choices:
1. Check if IsPostBack == false and leave EnableColumnsViewState == true
2. Don't check the IsPostBack property and set EnableColumnsViewState = false
Which is the correct approach?

May you give some advice on how to fulfill my scenario?

Best regards, Andrea Pirola

I add a RadEditor control to my aspx page, Since spell checking functionality not required, I didn't turn it on. Now problem is, When I run my application, I got runtime error, i.e., The spellchecking functionality of RadEditor requires a dictionary file named 'en-US.tdf'.

Since, this functionality is not required, why would I suppose to add this file?

Can anyone please tell me, how to disabled spell checking functionality?
