Hi Sir/Mam,

I am facing a problem in a RAD telerik editor controls inside an aspx page.  When i type the content inside the editor control and change the font to say (42px)  ,it shows fine and saves. But when i retreive it back , the content is fine , but when i select the content , the Font size dropdownbox displays 7 by default (istead of 42px). Please see the attached image.
Let me know why the editor is behaving in this way.

Hi Chiranth,

The RealFontSize dropdown header does not display some initially defined values, but it display the information of the current selection returned by the browser's queryCommandValue method. Since, the Font Size values in IE are static from 1 to 7 points (these are the values of the FontSize command), when the selection has 10px this method returns a value of 1 points, when the selection has 32px font size then the returned info is 6 points, 46px becomes 7.

You should just convert these point values to the corresponding values and set them through the args.set_value() method.

For your convenience I have wrote the code that will replace the point values from 1 to 7 with their appropriate values in pixels in IE, e.g.

Copy Code
<script type="text/javascript">
    function OnClientSelectionChange(editor, args) {
        var tool = editor.getToolByName("RealFontSize");
        if (tool && $telerik.isIE) {
            setTimeout(function() {
                var value = tool.get_value();
                switch (value) {
                    case "1":
                        value = value.replace("1", "10px");
                    case "2":
                        value = value.replace("2", "13px");
                    case "3":
                        value = value.replace("3", "16px");
                    case "4":
                        value = value.replace("4", "18px");
                    case "5":
                        value = value.replace("5", "24px");
                    case "6":
                        value = value.replace("6", "32px");
                    case "7":
                        value = value.replace("7", "46px");
            }, 0);
<telerik:RadEditor id="RadEditor1" runat="server" OnClientSelectionChange="OnClientSelectionChange">
        <span style="font-size: 10px;">text</span><br />
        <span style="font-size: 13px;">text</span><br />
        <span style="font-size: 16px;">text</span><br />
        <span style="font-size: 18px;">text</span><br />
        <span style="font-size: 24px;">text</span><br />
        <span style="font-size: 32px;">text</span><br />
        <span style="font-size: 46px;">text</span><br />

You can enhance the example when needed by adding your own checks and conversions.
