Dialogs - Reading Parameters at Server-Side

[David]

Hi

I'm aware we can pass parameters over when open a dialog via javascript as below:

var editor = $find("<%=txtEditor.textEditor.ClientID%>");

var openArgs = {};

openArgs.sender =

'AppendixRule';

editor.fire(

'TP_EditRule', openArgs);




These parameters can then be read using javascript in the dialog. However I was wondering if there is a way to read these on the server side page load of the ASCX control? ie ...

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

'HERE

End Sub


Thanks
David

Hello David,

Depending on whether the parameters you wish to pass are coming from the server or browser, there are two ways to do this. If your data comes from the browser, you can use the dialog's URL (querystring) to pass it to the server.
For example:

Telerik.Web.UI.Editor.CommandList.test  = function(commandName, editor, oTool)
{
    var oldAdditionalQueryString = editor.get_dialogOpener().get_additionalQueryString();
    editor.get_dialogOpener().set_additionalQueryString("&MyItem=MyValue");
    editor.showDialog("test");
    editor.get_dialogOpener().set_additionalQueryString(oldAdditionalQueryString);
    return false;
};

The parameters can then be retrieved easily on the server:

protected void Page_Load(object sender, EventArgs e)
{
    string param = Request.QueryString["MyItem"];
...

If your parameters are coming from the server, then you can use the Session object to pass them from the parent page to the dialog control.
