Im using RadFileExplorer in a page where i need to have ImageEditor option that has been available in the ImageManager in RadEditor Control or else is there anyway to use the ImageManager.ascx Control directly in a page and not as an dialog.

Thanks & Regards,

RadEditor setText using javascript

Hi there!

I have a RadEditor which have cientside validation of 4000 characters, my problem is the alert box message prompts when the characters exceeds 4000, but I can't set or change the text editor to maintain only its 4000 characters...

It seems that the code line > rtfEditor.set_text(oValue.substring(0, 30)); doesn't work.

Many Thanks!

Reynald

Here's the markup:

<

telerik:RadEditor ID="EdtDesc" runat="server" SkinID="radEditor1Skin" OnClientLoad="LimitCharacters"

OnClientPasteHtml="OnClientPasteHtml">

</telerik:RadEditor>

var editorList = new Object();

var editorLengthArray = [30, 30];

var counter = 0;

function isAlphaNumericKey(keyCode) {

if ((keyCode > 47 && keyCode < 58) || (keyCode > 64 && keyCode < 91)) {

return true;

}

return false;

}

function LimitCharacters(editor) {

editorList[editor.get_id()] = editorLengthArray[counter];

counter++;

editor.attachEventHandler(

"onkeydown", function(e) {

e = (e ==

null) ? window.event : e;

if (isAlphaNumericKey(e.keyCode)) {

var maxTextLength = editorList[editor.get_id()];

textLength = editor.get_text().trim().length;

if (textLength >= maxTextLength) {

alert(

'You are not able to type more than ' + maxTextLength + ' symbols!');

var rtfeditor = $find("<%=EdtDesc.ClientID %>");

var oValue = rtfeditor.get_text().trim();

rtfEditor.set_text(oValue.substring(0, 30));

e.returnValue =

false;

}

});

var element = document.all ? editor.get_document().body : editor.get_document();

$telerik.addExternalHandler(element,

"paste", function(e) {

e = (e ==

null) ? window.event : e;

var maxTextLength = editorList[editor.get_id()];

textLength = editor.get_text().length;

var clipboardLength = window.clipboardData.getData("Text").length;

textLength += clipboardLength;

if (textLength >= maxTextLength) {

alert(

'You are not able to type more than ' + maxTextLength + ' symbols!');

e.returnValue =

false;

return false;

}

});

}

function CalculateLength(editor, value) {

var textLength = editor.get_text().length;

var clipboardLength = value.length;

textLength += clipboardLength;

return textLength;

}

function OnClientPasteHtml(editor, args) {

var maxTextLength = editorList[editor.get_id()];

var commandName = args.get_commandName();

var value = args.get_value();

args.set_cancel(

true);

}

GridDateTimeColumn TimeSpan UpdateValues

I believe a bug exists when using a GridDateTimeColumn DataType="System.TimeSpan" PickerType="TimePicker" DataFormatString="{0:t}" and then attempting UpdateValues in the code behind. UpdateValues fails because the value returning is DateTime instead of TimeSpan.

<telerik:GridDateTimeColumn DataType="System.TimeSpan" PickerType="TimePicker" DataFormatString="{0:t}" EditFormColumnIndex="2" HeaderText="End Time" DataField="TimeEnd" UniqueName="TimeEnd" />

void RadGrid_UpdateCommand(object source, GridCommandEventArgs e)

{

var editableItem = ((GridEditableItem)e.Item);

var id = (long)editableItem.GetDataKeyValue("Id");

using (DataContext context = new DataContext())

{

var frequencyLocation = context.FrequencyLocation.ByKey(id);

if (frequencyLocation != null)

{

editableItem.UpdateValues(frequencyLocation);

context.SubmitChanges();

}

RadDateTimePicker Error: 'get_calendar()' is null or not an object

I ran into problem that RadDateTimePicker client object method "hidePopup" or "hideTimePopup" threw an error message: "'get_calendar()' is null or not an object".

Here is my code piece:

    
            function HideAllCalendars() 
        
            { 
        
                if( typeof(jQuery) != 'undefined' ) 
        
                { 
        
                    jQuery("div.RadCalendar").each(function() { 
        
                    if (this) 
        
                    { 
        
                        // find first INPUT child node 
        
                        var obj = null; 
        
                        for( var i = 0; i < this.childNodes.length; i++ ) 
        
                        { 
        
                            var node = this.childNodes[ i ]; 
        
                            if( node.tagName == 'INPUT' && node.id ) 
        
                            { 
        
                                obj = node; 
        
                                break; 
        
                            } 
        
                        } 
        
                        if( obj ) 
        
                        { 
        
                            var oo = $find(obj.id) 
        
                            if(oo && oo.hidePopup && oo.hideTimePopup) 
        
                            { 
        
                                oo.hidePopup(); 
        
                                oo.hideTimePopup(); 
        
                            } 
        
                        } 
        
                    } 
        
                    }); 
        
                } 
        
            }

The oo.hidePopup or oo.hideTimePopup will throw the error message. Here is the exact error in the Telerik resource file:

    
            for(var _32 in Telerik.Web.UI.RadDatePicker.PopupInstances){ 
        
            if(Telerik.Web.UI.RadDatePicker.PopupInstances.hasOwnProperty(_32)){ 
        
            var _33=Telerik.Web.UI.RadDatePicker.PopupInstances[_32].Opener; 
        
            this._hideFastNavigationPopup(_33); 
        
            Telerik.Web.UI.RadDatePicker.PopupInstances[_32].Hide(); 
        
            } 
        
            } 
        
            },_hideFastNavigationPopup:function(_34){ 
        
            if(_34){ 
        
            var _35=_34.get_calendar()._getFastNavigation().Popup; //Error Happens here! 
        
            if(_35&&_35.IsVisible()){ 
        
            _35.Hide(true); 
        
            } 
        
            } 
        
            },_setInputDate:function(_36){ 
        
            this._dateInput.set_selectedDate(_36); 
        
            },_getJavaScriptDate:function(_37){ 
        
            var _38=new Date(); 
        
            _38.setFullYear(_37[0],_37[1]-1,_37[2]);

Why does the error happen? please help. Thanks.

AJAX call from Grid EditTemplate Control?

I have a RadGrid with 3 columns in the master table only: 2 are read only and the other is an EditTemplate with a RadTextBox. If in edit or insert mode and after the value of the textbox changes and loses focus, I want to do an AJAX call which will query the database for the newly entered value and then populate the 2 read only fields from the results. So to the user, the 2 read only fields appear to get "auto populated" after the value of the textbox changes. Is this possible? All I really need help with is getting the textbox to call a sub in the codebehind. I should be able to take it from there.

Thanks!
