Questions on UI for ASP.NET AJAX Forum

We are using RadScriptManager with the Ajax Proxy. We are experiencing some issues if users are quick to press buttons (I am thinking prior to the page completely loading).

For example,

The below code will do a postback if clicked quickly versus if you wait for the page to fully load. If you wait for the page to fully load it does what it's suppose to do, and just run the local javascript.

<telerik:RadButton id="addLocationButton" runat="server" text="Add Location" width="100" OnClientClicked="UpdateQuickPanel" AutoPostBack="false" />

Do you have any ideas what is causing this behavior and how to prevent it?

Thanks,
Todd.

RadGrid insert/update extremely slow

Hi!

I am having an issue using a radgrid in a project. Everything works great, except when I make an insertion into the grid, the whole browser freezes for about 5 seconds. While the browser is frozen, the ajax loading panel is displayed, but the "loading circle" in the middle does not turn. It is also frozen.

Has anyone expirimented this issue before?

Thanks,

Alex

Setting filter function via custom FieldEditor

I've created a custom field editor which has:

Two radio buttons, radio1, radio2 with autopostback = true
A text box
A combo box (as described in the demo : http://www.telerik.com/help/aspnet-ajax/filter-custom-editors.html)

I have it coded like this:

When radio1 is selected, the textbox is visible, and the filter functions are EqualTo, NotEqualTo, Contains, Between, etc.
When radio2 is selected, the combo box is visible, and the only filter function is EqualTo.

My problem is when radio2 is selected, I can't figure out how to set the selected filter to EqualTo. For example, If radio1 is selected and the selected filter function is 'Contains', and then they select radio2, I can't set the selected filter to 'EqualTo'. I can reduce the options available in the context menu successfully when radio2 is clicked, but I can't set the selected filter.

Please help :)

Thanks,
Josh

And when i trying to insert o edit a record, the display it's weird. It's posible to correct the widht of the columns in the EditForm and the size of the items inside without using a Template?

I interested in obtain a result like the design of the Grid / Edit Form with Multiple Columns example. With columns with equal width and centered items.

Felipe Meléndez.

RequiredFieldValidator on RadWindow

As a new user of the Telerik controls I am still feeling my way around - I'm used to the Infragistcs control suite so I'm sure there is something simple I am missing. Here is the problem:

1) Master Page with standar header/footer, content panel
2) Child Content Page with RadGrid, RadToolBar
3) RadToolBar has an "Add" button which does an async postback - the handler calls a method which configures the Title and IconUrl of the RadWindow (since it functions for both "add" and "edit") and then adds script function call to open the RadWindow - works fine - the RadWindow opens as expected.
4) There are two asp:TextBox controls on the RadWindow and both have RequiredFieldValidators configured
5) There are two buttons - "Cancel" and "Save" - the cancel button functions fine and prompt's user to confirm cancellation and closes the RadWindow if true otherwise does not. "CausesValidation" is set to false on the Cancel button.
6) The Save button has "CausesValidation" set to true - but when I click the button the validation does not appear to work because the page post's back and I get an error because I'm trying to save a record with no values.

The question is, why are the RequiredFieldValidators not "firing" - I expect the error text to show and focus to be set to the control failing validation - am I missing a setting or something?? Here is the content page markup...also attached an image of what the page looks like when the RadWindow is opened in "add" context.
