RadWindow clientCallback

[Shed Dweller]

The documentation is a bit light on how to use clientCallback().

What do you do in the opened window in order to return data.

I used to do this alot with window.showModalDialog().  You can return all kinds of objects e.g. even 2D arrays with it. I may have to resort to using it since I know my target browser isIE.

Hello Sean,

I believe that the Using RadWindow as a Dialog topic in the documentation will be of help. It shows how to send arguments to the parent page depending on whether you will read it in the ClientCallbackFunction or in OnClientClose.

Thanks

However it seems I can only return text to the calling window so I probably will resort to window.showModalDialog() since I need to to return an array of values.

Hi Sean,

In fact you can return any javascript object (regardless of whether it is a string or array or something else).

Sean,

You'll find that you can return any JS object as the result.

Here's a bit of code I've just pulled out of one of my apps that is called, in my case from a grid dbl-click where the grid is displayed in the radWindow ...

var oWindow = GetRadWindow();
var arg = new Object();
arg.popupType = document.getElementById("__PopupType").value;
if (arg.popupType == "picklist") {
  var mainColumnName = document.getElementById("__MainColumn").value;
  if (mainColumnName != "") arg.mainColumnValue = masterTable.getCellByColumnUniqueName(row, mainColumnName).innerHTML;
  var displayColumns = document.getElementById("__DisplayColumns").value;
  if(displayColumns != "") {
    var displayColumnsArray = displayColumns.split(",");
    var displayColumnsValue = "";
    for(var i=0; i<displayColumnsArray.length; i++) {
      if (displayColumnsValue != "") displayColumnsValue += ",";
      displayColumnsValue += masterTable.getCellByColumnUniqueName(row, displayColumnsArray[i]).innerHTML;
    }
  }
  arg.displayColumnsValue = displayColumnsValue;
}
arg.dbfr = dbfr;
oWindow.Close(arg);

Hope this helps.
