[Solved] Problem calling Radalert from code

[Daniel]

Hi. In many parts of my application when an item gets deleted I show a radalert to confirm to the user if the item has been deleted successfully or not. This has worked for me well until I needed to attach a radconfirm before the radalert. The js error that appears is "object doesn't support this property or method". This is all happening from a radtoolbar so I've followed the article here to get the radconfirm working. A regular js alert works okay.

This code has worked for me in the past.

if (rows >= 1)
{
    script = @"var oWnd = radalert('The item was deleted successfully. Click OK to redirect to the Q&A home page.', 330, 210); var browserWin = oWnd.BrowserWindow; var fn = new browserWin.Function('oWnd', 'window.location.href = ""/teams/hr/qa/""'); oWnd.add_close(fn);";
    //script = @"alert('The item was deleted successfully. Click OK to redirect to the Q&A home page.'); window.location.href = '/teams/hr/qa/';";
}
else
{
    script = @"var oWnd = radalert('An error occurred deleting the item. Please contact the ServiceDesk on x4555. Click OK to redirect to the Q&A home page.', 330, 210); var browserWin = oWnd.BrowserWindow; var fn = new browserWin.Function('oWnd', 'window.location.href = ""/teams/hr/qa/""'); oWnd.add_close(fn);";
    //script = @"alert('An error occurred deleting the item. Please contact the ServiceDesk on x4555. Click OK to redirect to the Q&A home page.');";
}
myAjaxManager.ResponseScripts.Add(script);

Thanks

Hi Daniel,


The KB Article describes better on showing radalert from code.
Calling radalert from codebehind

Thanks Shinu. Unfortunately all those methods produce the same js error. This only happens when I follow the knowlege base article above. If I use standard js functions like alert and confirm I get no errors.

Hi Daniel,

 The article Shinu has pointed covers all the scenarios with opening a radalert from code-behind. In case you need further assistance, we will really need to examine your setup because if this does not work, there might be something specific in it, e.g an incorrect or missing ajax setting, etc. This being said, please prepare a sample, fully runnable reproduction demo along with detailed reproduction instructions (you can bind the grid to a fake programmatic datasource for simplicity), open a new support ticket and send it to us.

On a side note, I am glad to inform you that with the upcoming major Q1 2011 release which is scheduled for march, the RadWindowManager will provide server RadAlert, RadConfirm and RadPrompt methods which will help you easily invoke a dialog from the server without registering script and no matter ajax or RadAjax or no ajax is used.

Best wishes,

Svetlina
