RadAjaxManager, RadInputManager & asp:FormView

Hi,

In my application I have some simple asp:formviews for changing some settings of a specific record. In this case the password.
The form has three buttons, one for the formviews canceling event, one for the formviews update event and one which do some other staff on the server-side.

The two password textboxes requires validation done by the RadInputManager.
The TextBoxSettings are appended in the formiews ItemCreated event.

When calling the page the first time all looks fine, validation works and skins are applied. After clicking the update or the cancel button the TextBoxSettings are not appended to the textboxes and there is no validation.
On the other hand, when I click on the third button all works fine.

Has anyone an idea what I'm doing wrong? Is there an Rad equal to asp:formview ? How are others editng forms? Please note the this is only a small example. I have a lot of more complex asp:formviews in my app

Here ist my code

<%@ Page Title="" Language="C#" MasterPageFile="~/portal/PartnerPersSettings.master" AutoEventWireup="true" CodeFile="PartnerAccess.aspx.cs" Inherits="www.sw_xperts.com.portal.PartnerAccess" %>

TreeView - Hierachy support for non-numeric parent ID's

When showing a hierachial set of data in a treeview, can the ID and ParentID fields be non-numeric? Specifically i have a datatable where the ID and Parent IDs are GUIDs.

I was able to get things working if i used integers for the id and parent id fields, but not for strings.

thanks in advance.

Javascript Error this.get_value().replace is not a function

Hi,

I am running into a weird issue with this XmlHttpPanel. It used to work (from a very old version, 2009.3.1208) until I updated it to the newest version just released.

The problem happens when I want to use the $find('the panel').set_value() to initiate callback. It now works on some of my pages, but not all of them. See attached for the detailed error message.

Filtering = StartsWith + Contains / MarkFirstMatch = true

I need to run the filter with ComboBox and Contains StartsWith + MarkFirstMatch =true

Sample items

Ana Maria
Antonio
Felipe
Fabio
Maria Ana

My combobox is specified as with Contains.

Value: Maria

It appears the items:
Ana Maria
Maria Ana

All right. Only he focuses on the first "Ana Maria" but I wish he focuses on "Maria Ana" Butit still appears the "Ana Maria".

How do I do this?

I tried using the OnClientKeyPressing but does not work correctly: .highlight();

Drag from RadGrid to RadTreeView, not cancelable?

Edit: Figured out my issue. The API doesn't directly support dragging and dropping to and from you have to do some very manual mouse work and through that I figured out nicely how to "cancel" it.

Need info about trial version

Hi guys

I'm in the process of getting ready to upgrade to the new controls from my 2009 version.

I would like to use the trial version on one of my systems to test user experience. Will the trial version display the "This is a trial version" message all the time, or only after the trial has expired?

GridBinaryImage creates huge bmp files

Greetings,

We're using GridBinaryImageColum to upload jpg images whose size is about 100KB.
These images are saved in a varbinary columns in a database.
When calling these images on the front-end, we get bmp images that exceed 1.1MB.

It that normal?
Is there a way to avoid the size jump, or is it simply better not to use the BinaryImage for such scenarios?

Thanks in advance.

How to avoid RadAjaxLoadingPanel

Hello,

I am using a RadGrid that should be refreshed every 2 seconds.I setup a asp:timer and RadAjaxManager on the page and everything is working fine. What I would like to acheive is to avoid the RadAjaxLoadingPanel to be shown douring refresh; in other words I would like to get the new rows in the Grid without showing to the user that the page is loading again.
If I am seeting the RadAjaxLoadingPanel visible = false, the grid doesn't refresh and the same if RadAjaxLoadingPanel is not set within RadAjaxManager.
Do you have any suggestion?

Thanks, Giuseppe
