Hi

I've been playing with the demo's and really like the AJAX kit so will be buying it once I get paid for my current job, but whilst using the trial version I have come across an error with the RadTooltipManager and would appreciate some help if anyone is able to please.

Basically it works fine everywhere on the site, apart from the home page, but to make it more confusing it doesn't work when loaded via http://www.domain.com/ but it does work when I add default.aspx so http://www.domain.com/default.aspx

The error I get is:

RadToolTipManager response error:
Exception=Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 405

I've also attached a screenshot of the error.

My code is:

default.aspx


default.aspx.vb


I've just re-downloaded and re-installed the trial, to make sure it wasn't something to do with that.

Many thanks in advance.

Hi Telerik,

As a disclaimer, this question is vague. My issue is that, under certain conditions, a RadWindow will re-open itself and become non-responsive to user interaction. For instance, if I have some client-side code which is executing (may or may not center the RadWindow), and the user closes the window before this code finishes executing. Then, when the code finishes executing, the window pops back open! If the user clicks on the 'X' it does not close the window.

I suspect this is entirely my fault... possibly should not allow closing of the window until fully loaded, or find a way to cancel client-side script execution. Regardless, I was looking for a blanket fix to make sure this problem doesn't accidentally rear its head to a customer.

At this point, I'm doing something like this:


In this scenario, I handle the browser window resizing. If there is an open window, I would like to move it back to the center of the page. It is my impression that calling oWindow.center on an element which is defined, but not visible, is dangerous in that it may show the window again?

Does what I'm doing make sense? Have you heard of other users experiencing similar issues / is there a standard way of handling this? Or is it just "code better and not defensively" and make sure that the state of my window is such that at any point in time, if its closed, it can respond intuitively.

Cheers,

Sean

I trying to figure out how to pass the name of a wave file that is displayed into the file explorer. So when the user double clicks on the file name, it plays in a media player that is next to the file explorer (see attached screen shot).

Currently if you double click the file name a window opens and the wave file starts playing. That doesn't work to well as if you close the window the calls keeps playing.

I need to pass the JavaScript var "name" to in the Windows Media Player control and not have the file explorer default to
popping up a window and using the user's default media player.

Any suggestions????

Thanks,
Joe

Here's the code I have got so far...

Here is my grid:


It's in a radwindow, so I need to be able to loop through the grid and compile a list of items where the checkbox is checked. 

I saw the example where you can set it to postback on the check changed event, but I'd prefer not to have to rebuild the string and postback everytime something is checked.

Is there anyway to do a loop through in javascript?

Thanks.

I have a RadGrid with a GridClientDeleteColumn. The table also has a ItemTemplate with a RadNumericTextBox so values can be entered and udpate a total in the footer client side just like this example.

http://mono.telerik.com/Controls/Examples/Integration/GridAndInput/DefaultCS.aspx?product=grid

However, because of the DeleteColumn, whenever a user enters a new value in the TextBox on a row, and hits enter, the row gets deleted, it's firing off the delete event? Why? If I remove the DeleteColumn, of course, this no longer happens.

I tried adding OnClientEvent OnKeyPress event handler to capture the enter being pressed but can't find the documentation to tell me what the 'isEnterKey' property name is that shows in the debugger

Can I disable this somehow so the delete doesn't occur on pressing the enter key and the user has to click the delete button?

<telerik:GridClientDeleteColumn ButtonType="ImageButton" HeaderStyle-Width="25px" ItemStyle-Width="25px" />
...

 

 

 

<telerik:GridTemplateColumn UniqueName="awardCol" DataField="Amount" HeaderText="Amount">

 

 

 

<ItemTemplate>

 

 

 

<telerik:RadNumericTextBox ID="amountEntryField" DataType="System.Double" MinValue="1.0" Value='<%# Eval("Amount") %>' runat="server">

 

 

 

<ClientEvents OnBlur="amtBlur" OnFocus="amtFocus" OnKeyPress="updateAmount" />

 

 

 

</telerik:RadNumericTextBox>

 

 

 

</ItemTemplate>

 

We are using Radeditor export to PDF feature to generate a Radeditor contents into PDF format and saving it to sharepoint document library.
We wanted to make reverse of this functionlity i.e wanted to replace a Radeditor body with PDF contents so that user can edit contents and genrate a new PDF again.
How can we implement this scenario. 

I have a Radcombobox that is bind from the database.
i have put the following properties TRUE
ShowMoreResultsBox=true
EnableVirtualScrolling=true
EnableLoadOnDemand=true
ItemPerRequest=20
it works fine.
Suppose i add a Employee record. on the Employee add form there is a Radcombobox that have the Cities filled with it from the City table in database. when i click on the Radcombobox with each request next 20 cities are shown, its fine. Selected city suppose "California" is selected and inserted in database.
now when i come in edit mode i write down the code to select the california that was already added in database.
RadCombobox1.SelectedValue=20;  //California State ID from the database.
but it is not shown by default unless we click on the radCombobox.
I want that Seleceted state should be displayed by default and as well as pagination should be worked with above mentioned properties.
