Please take look at the following code:

 

<telerik:RadTextBox runat="server" ID="txtAddress" Text="Test Text" TextMode="MultiLine"  Rows="2"  Skin="WebBlue"/>  
<asp:Button runat="server" ID="btnReset" OnClientClick="document.forms[0].reset();return false;"  Text="Reset" UseSubmitBehavior="false" /> 
 

Let's enter some new text in the input text box and then click on the Reset button.

In FireFox 3.5.6.
    -Text box will be cleared
In IE 8 
    -Text box is not changed

In both cases original text will be displayed only when you give focus to text box.

Hello Igor,

Please use the following approach, which will be incorporated in the next version of RadTextBox. Note that the custom Javascript code must be registered after the embedded one, i.e. you have to place it in the <body> or inside an external JS file, which is included in the <body>.

I have updated your Telerik points for this bug report. Thanks.

I tried to insert this script in my code,  but nothing happen.

 

I have added alerts in script and found that typeof

 

(Telerik.Web.UI.RadInputControl) is always  "undefined".
Please advice.

Hi Igor,

Did you try running my sample page? Does it work on your side (it should) ?

Probably you have included the script somewhere before the embedded script files. Another option is that your are making the RadTextBox visible after AJAX request. In this case you need to execute the custom script after you have shown the control (e.g. call it from another function).

You are right, Ajax request was a reason. Thanks.

Hello,

I have the same problem   with RadDatePicker conrtol. I use the code below.

 

 

 


I enter dates and click on "Search" button
I click on "Reset" button, Dates  will be cleared but on focus will be appeared again (IE 7)

Actual Result:
Previous dates are available again .

Expected Result:
On Reset fields should be empty

Thank you in advance

<telerik:RadDatePicker ID="txtDateFrom" runat="server">   
 
</telerik:RadDatePicker> 
 
 
 
<telerik:RadDatePicker ID="txtDateTo" runat="server">   
 
</telerik:RadDatePicker> 
 
 
 
<asp:Button OnClick="btnSearch_Click" ID="btnSearch" runat="server" Text="<%$ Resources:AdminResources, SEARCH %>" />&nbsp;&nbsp;&nbsp;<input id="Reset1" type="reset" value="Reset" />

Hello Yvonne,

I can't reproduce the described behavior with RadDatePicker. Which RadControls version are you using?

I use the latest version --> 2009.3.1314.35.
You submit the form with some selected dates and, after the postback, you click on reset button,the dates are disappeared but on focus are appeared again.

Hello Yvonne,

We tracked down the problem and fixed it. Changes will take effect in the next official release (Q1 2010 due in March), next beta (Q1 2010 Beta due next week) and next RadControls internal build (uploaded 1-2 times a week).

I have updated your Telerik points. Thank you.

All the best,
