[Solved] Server Method failed

[Jyoti]

I am using the RADcombobox for the autosuggest feature. I have a webservice with a webmethod, say, 'MyMethod' which is being used to populate the combobox with the auto suggested values.

If I type something in the Radcombobox input area, the webmethod is called. If I try to navigate away from this page by clicking any other links or buttons on this page, before the webmethod returns with values, I get an error - "Server Method MyMethod failed".

No other error messages. Please advise.

Did anyone come up with a solution for this?

[Jyoti]

Yes I did. Handle the client- side event - 'OnClientItemsRequestFailed'. 
 

<

 

telerik:RadComboBox ID=...

 

...

OnClientItemsRequestFailed

 

= "ClientItemsRequestFailed"

 

>...

</

 

telerik:RadComboBox>

 

Define a js function and write the following code in it -

 

function ClientItemsRequestFailed(sender, eventArgs)

 

{

eventArgs.set_cancel(

true);

 

// Your custom error handling if reqd.
}

Thanks for you reply. I meant were you able to get it to work (call the webservice of page method)without throwing that error.

Hi Konzab,

You can avoid this issue by preventing the postback during a pending web service call by doing the following:

• Handle the client-side ItemsRequesting event of the RadComboBox and set a global flag to true.
• Handle the client-side ItemsRequested event of the RCB and set the global flag to false.
• Handle the click events of all Buttons/Links on your page and cancel them if the flag is set to true.

Sincerely yours,
