Hi,

We have a gird with a export function. It works very well. However, when there are 5000 items in the grid. Once fire the export function, it will give a exception:"

System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

"

I was wondering if export function has a maximum limit or if you have any solution for this.

I appreciate your help

Thanks,
Feng

I'm following the example  for cascading combo-boxes as found at: http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/multiplecomboboxes/defaultcs.aspx

In my exmample I just have Country / City(region)

The problem I am having is this... I have the code working where the Country uses the OnClientSelectedIndexChanged which calls my javascript function "BindRegions"...  BindRegions in turn uses the Client-Side API and calls the regionsCombo.requestItems() method to cause an AJAX call to occur back to the server-side code for the apporpriate combo box.  The Regions combo box is databound (refreshed) in that event and then the expected client-side javascript call to ItemsLoaded occurs which selects the 1st item in the list.

When I click a 'Update' button on my form (CommandName="Update" defined on the button - no click event code present) a series of events occur and eventually I invoke a method which populates an entity from the controls on that screen (which actually is a user control template for a grid editor template).   When I check the controls, their values are not set to the expected values - which I suspect is due to not having AutoPostBack enabled - which leaves me in a pinch.

How do I do the "client-side/AJAX" approach but still have the correct values up in the server-side code?   On a prior project where we had cascading combo-boxes (i.e. Country/State or Year/Make/Model) it was done with AutoPostBack enabled and no client-side javascript at all...

So I have 2 questions....

(A) which is the "right" approach - using RadAjaxManager and Post-Backs or the example given from the ComboBox section of the web-site - this was frustrating in that the 'reccomended' approach is what I would expect to find here... 

(B) How do I make the approach shown at the link stated above work while still having access to the right 'selected' values (SelectedItem, SelectedValue, SelectedIndex, etc)...

Hi,

I'm getting this error after FormView Updated or Inserted :
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Script control 'gridEnderecos' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().

Here is my code:


What is happening??

Hi,
I have been trying to figure out how to make a multicolum combo look nice. I would like to have a border on each side of the table cells but I've found that when I do that there is a gap at the top and bottom of each cell. This makes the border on each side look silly.
How can I make the border on the left and right of each cell look like a single line going down the columns?
Thanks ... Ed


I have the following snippets to illustrate.

is it possible to disable the edit on the back end.. I need to have the user still click the subject however I want to do something different on the back end...  I tried to do 

rsLocationCalendar.AllowEdit =

false;
however it did not do anything... I saw a sample but cannot seem to get it to work in the front end... Any help you can give would be great.

 

Hi,

I have a rad grid which has a calculated column.

<

 

telerik:GridCalculatedColumn HeaderText="User's Name" UniqueName="UsersName" DataType="System.String"

 

 

DataFields="FirstName, LastName" Expression='{0} + "&nbsp;" + {1}' AllowFiltering="true"/>

If an user's name is Peter James and I filter the grid by first name or last name it works fine.If I filter for the full name Peter James,there are no records displayed in the grid.

Could you please let me know how I can filter the grid by full names( FirstName LastName).

Thanks,
Nandita.

 

Hello,

I have a client-side OnCommand handler setup for the RadGrid.  It's setup for a page event on the client side, but for some reason, it's being called twice.  I don't know what the issue is there... why would it be called twice?

Thanks.
