Unable to enter the Percent symbol in the Width and Height textboxes of the Image Options dialog when using French keyboard


The problem is due to different keyCode of the % symbol when using French keyboard. That's why the validation mechanism of the Width and Height fields does not allow it.


To allow the % special symbol when typing in French, create a new Dialog.js file with the following contents:


if (Sys && Sys.Application) {
    Sys.Application.add_init(function () {
        if (Telerik && Telerik.Web && Telerik.Web.UI.Widgets && Telerik.Web.UI.Widgets.ImageProperties) {
            var oldInit = Telerik.Web.UI.Widgets.ImageProperties.prototype.initialize;
            Telerik.Web.UI.Widgets.ImageProperties.prototype.initialize = function () {
                this._allowedASCII = new Array(8, 16, 35, 36, 37, 39, 45, 46, 165, 192);

and import the script file in the Set Image Properties dialog via the DialogsScriptFile property:


<telerik:RadEditor ID="RadEditor1" runat="server" DialogsScriptFile="~/Dialog.js">
        <img src="Images/Apply.png" />

The DialogsScriptFile property allows to import JavaScript content in the RadEditor dialogs similarly to the DialogsCssFile property which allows to import custom stylesheet in them.
