Issue w/ Uploading more data than Downloading w/ AJAX

I have a large test Sales Order application that contains Telerik, and ComponentArt controls. I have a Telerik Script Manager, ComboBox, AjaxManager, and a Component Art Grid. I've had a horrible experience with the CA controls, and am in the process of converting all the controls to Telerik (btw they are 10x better!).

I have a ComboBox that queries 9000 items, and returns 25 per page. When an item is selected it calls an AJAX function and returns item information.

When calling the AjaxManager I send 40 KB, and receive 8 KB. At first I thought it was my ViewState, so for testing I disabled it on the Page and AjaxManager. Still the same. I have included a link to an HttpWatch log of this problem. Do you know what might be the issue?

Lots of RadNumericTextBox - very slow compared to asp:Textbox

Hi

Iam recreating a old application from ASP, the application is a data input application, it has everywhere from 1 to 300 rows.
I have a RadGrid, (performing very well), within these RadGrids i have 4 TextBoxes for each row, encapsulated by an ItemTemplate.

The thing is with 100 rows i will have 400 textboxes, this is no problem at all using ASP:TextBox (site loads within 1 second) however doing this with RadNumericTextBox it takes 8-9 seconds loading and then another 4-6 seconds where the UI freezes up (might be some style adjustments or something.)

Is this just the way it is or am i doing something wrong ?

Iam using RadNumericTextBox because it has a very nice way of showing illigal inputs and automatically limits the input.

Grid column Count

Hi,

We have a radGrid with one pre-defined checkbox column. To this grid we bind a dynamically generated datatable. Based on a certain logic we have to hide some of the columns in the grid. We are using the following code piece

Sub Page-Prerender
grdlist.datasource=databale
grdlist.databind

For Each col As Telerik.Web.UI.GridColumn In grdList.Columns

If col.UniqueName = "Field to Check" Then

col.Display =

False

Exit For

End If

Next
end sub

However the Grid seems to have only one column even in the page prerender hence we dont get to access the column at all. Which event must be used to hide a column?

Issue #2

BTW i also see the checkbox column always grayed even though i have given "REadonly" as "false". What we need is to give a user functionality to click the check boxes and click delete / assign.

1. How to enable the checkboxes in the grid
2. How to get the checked items.

Index was out of range exception on legend click

Hi
I've set up onclick handler for the chart to enable the user to click on the bars and get detail info on the series item (the items are added programmatically and this seems to be the only was to to handle the click). Is there a way to prevent the onclick event firing when the user clicks on the legend? I'm getting the followin exception:

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Thanks

RadGrid Editing using Entity Framework Causing Error

I have two tables.
STAFFMEMBER
StaffNumber : int PK
FirstName : nvarchar(50)
LastName : nvarchar(50)
TeamID : int FK

TEAM
TeamID : int PK
TeamName : nvarchar(50)

Using the entity framework and RadGrid (2008.3.1105) I am attempting to edit the staff members. Retreiving the list of staff members requires me to include the Team object in oder to update and view the team they belong to. I therefore have to use an object query instead of the EntityDatasource (which works) to navigate the object graph.

In my StaffGrid_NeedDataSource method I have the following code:

    
            protected void Grid_NeedDataSource(object source, GridNeedDataSourceEventArgs e)  
        
            {  
        
                StaffGrid.DataSource = context.StaffMembers.Include("Team").OrderBy(p=>p.LastName);  
        
            }

When I select a row to edit via a LinkButton, with CommandName="Edit" I get the following error:
"The ObjectContext must be configured by 1) defining ContextTypeName, 2) defining both ConnectionString and DefaultContainerName, 3) defining ContextType, or 4) supplying it in the OnSelecting event."

These attributes in the error are defined in an EntityDataSource which I am not using due to my customised object query.
I have been using RadGrid for a long time with the ObjectDataSource and am moving to the Entity Framework.

What exactly am I missing or is this not fully supported?

	protected void Grid_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
	{
	StaffGrid.DataSource = context.StaffMembers.Include("Team").OrderBy(p=>p.LastName);
	}
