Eat first keystroke on ajax post from client

When checking to see if the document has been modified, I’m having a problem where the first key stroke is eaten. On the first key stroke that makes the document dirty I send an ajax message to the server indicating the document is dirty and it is that first key stroke that gets eaten. Other key strokes are ignored and no messages are sent. Of course I’m assuming it’s the interaction with the ajax message that causes the key stroke to be eaten.

Was wondering if anyone had a suggestions what to look into.

Thanks.

Client Side

function OnKeyDown_Editor(e) {

//debugger;

if("<%=AllowTextEntry%>".toLowerCase()=="true".toLowerCase()){

if(isPrintable_orDelete(e.keyCode)){

SetDocumentDirtyState(true);

}

…

e.returnValue = <%=AllowTextEntry%>;//set to true most times

}

function SetDocumentDirtyState(MakeItDirty){

var IsDirty=GetCookie("<%=EditorDirtyCookieName%>");

if(MakeItDirty==true){

if(IsDirty!='true'){

/*

* write code to lock this document in database

*/

var message="EditorIsDirty-true";

SendAjaxMessage(message);

}

SetCookie("<%=EditorDirtyCookieName%>",true,1);

}

else{

deleteCookie("<%=EditorDirtyCookieName%>");

}

}

Filter textbox and default skin

Hi,

I wonder, how can I achieve one thing: I have defined skin (in asp.net meaning of that word) in default.skin, to set appropriate skin to all telerik textboxes:

<telerik:RadTextBox runat="server" Skin="Vista" EnableEmbeddedSkins="true" />

This works fine for every textbox - appropriate skin is set to control. The only problem I'm having is, that filter textbox on RadGrid doesn't seem to respect this element. It's still rendered as it's defined in skin (for RadGrid I'm using custom skin).

Now, I would like filter textbox to use settings from default.skin file.

I've had no problem with RadComboBox used as filter control in my custom column class, skin was automatically applied. Why same thing isn't happening to textbox? And how could I achieve my goal?

Thanks in advance

Ajax Loading Panel in Firefox

I have a radgrid that displays a radajaxloadingpanel upon update.
In IE, when update occurs, the entire grid is greyed out with the loading panel (desired). However, in firefox, if the user scrolls down to update a row that was not originally not visible, the greyed out effect of the loading panel only affects the originally visible rows in the grid. So if a user has scrolled so far down that none of the original rows are visible, they receive no feedback that anything is executing.

RadEditor does not convert characters to entities

Hello,

I just upgraded to Telerik 2010 Q3.

I am facing issue to convert the characters to entities.
For eg.
If you paste this string "

若要以中文阅读此电子邮件，请单击此处。

" (this resembles chinese characters) in html view and switch to design view it shows the chinese characters properly.
Again if you switch to html view it shows the same chinese characters in there where as it should show the unicode/entities for the characters.

I tried setting "ConvertCharactersToEntities" contentfilter but that didn't help too.

You can reporduce the above scenario in the built-in content filters demo.

Due to this "?????" is saved in db or when I write the content in file using RadEditor.Content property which returns the chinese characters as it is.

I want to display chinese characters in design view and in html view it should show the entities/unicode numbers for the characters.
By doing this RadEditor.Content property will return the unicode numbers and so in DB proper values will be saved.

Please help me in this senario.

Thanks in advance

RadPrompt with delete column

I've gotten the RadPrompt working along with the Delete button column. The End user will click the delete button on a row, the radprompt will open and the user must input a reason for the deletion. Then he clicks OK, I take the text through the args passed to the clientside and store it in a hiddenfield and then I need the Radgrid to resume the Server Side OnDeleteCommand code that is already wired. I know that I'm probably going to need to raise this on the client side once the radprompt closes. However, I cannot find any way of doing this. Help please!

How to conditionally show alert based on the RadioButtonList Selection.

Folks,

I am using RadControls for ASP.NET AJAX Q3 2010 SP2 with VS2010. I am using Form Template for editing rows. Below is my code.

In my form I have a RadioButton list (RadioButtonListApprovalType) with 3 list items. (Approved, Denied and Pending). I would like to see if the user's selects 'Denied', prior to updating the form, show an alert (i.e. 'Are your sure to Deny the Process?'). If user's chooses 'Yes', Update the row. If user's chooses 'No', Cancel the update. Basically I would like to see the same sort of alert prior to Deleting Radgrid rows.

Thanks
