Hello Fabrizio,

You could try to use Try-catch statement in JavaScript.

try
  {
  //Run some code here
  }
catch(err)
  {
  //Handle errors here
  }

Hope this helps.

Thank you.

Hi Martin,

sorry but I have forgot the attachment picture.

I know how to use the Try-catch statement but I don't know where add it to intercet the following exception and the change the error message (in attachment).

I add a new position in the WebGrid and the client is unabled to comunicate with server, now where I can put the your example (Try-catch statement)  to catch the exception, in any event ?

I hope that I'm clear

thanks

Hello,

Use OnUnhandledError Client-side event to catch the exception and put the following code:

function WebGrid1_OnUnhandledError(controlId, tblName, lastRequestObject, errorString)
{
   var WebGrid1 = ISGetObject(controlId);

   window.setTimeout(function(){
   var errorMessage = document.getElementById("wg_ErrorMsg"); 
   errorMessage.innerText = "Customize your error messages";}, 10);
            
   return true;
}

Hope this helps.

Thank you.

Thank you Martin,

this the event that I look for but now I don't know replace not only the Message but put our custom form with message, may you tell I can do it.

thanks very much

Hello,

You can use your custom form to override/replace the current form created by WebGrid. Try the following code:

function WebGrid1_OnUnhandledError(controlId, tblName, lastRequestObject, errorString)
{
   var grid = ISGetObject(controlId);
   grid.SetIdle();
   grid.IsInProgress = false;
   grid.SetStatus1("", "ready", "CommonText/Ready")

   alert("Customize your error message with custom Form");
   return false;
}

The code above will invoke alert function which will create a dialogbox with a custom message. Therefore, you can use your own custom Form in here.

Hope this helps.

Thank you.

Thank you, it is OK
