Not able to set value to Radtext box on Key down event

[Jidesh Guptha]

Hi,

I have a scenario where i have to display No. characters entered in a multi line text box on a text box.I have done the following code.

<telerik:RadTextBox ID="txt_Comment" runat="server" TextMode="MultiLine" Width="50%" Height="50px" onKeyUp="txt_CharacterCount.value=this.value.length" MaxLength="255">
</telerik:RadTextBox>

<telerik:RadTextBox ID="txt_CharacterCount" ClientIDMode="Static" runat="server" ReadOnly="true" Width="40px">
</telerik:RadTextBox>

Its not working for Rad Textbox. but the same is working for aspText box. How do i fix this issue. Pls guide me.

Hello Jidesh,

You can attach the OnKeyPress event instead of onKeyUp event like below.

aspx:

<telerik:RadTextBox ID="txt_Comment" runat="server" TextMode="MultiLine" Width="50%"
         Height="50px"  MaxLength="255">
         <ClientEvents OnKeyPress="OnKeyPress" />
 </telerik:RadTextBox>

Javascript:

function OnKeyPress(sender, args) {

     txtbox = sender;
     var count = txtbox.get_textBoxValue().length;//Since the event fired before keypress occurs,add 1 to get exact count
 }

Thanks,
Princy.

Hi Princy,

But this did not suite my requirement because this does not capture the backspace key press and also calculating the new line char.
can i use keyup event some how?

thanks

Hello Jidesh,

Modify the code as shown below and see whether it helps.

aspx:

<telerik:RadTextBox ID="txt_Comment" runat="server" onkeyup="test();" TextMode="MultiLine" Width="50%"
Height="50px" MaxLength="255">
</telerik:RadTextBox>

Clientcode:

function test()
 {

      var textBox1 = $find('<%=txt_Comment.ClientID %>');
      var textBox2 = $find('<%=txt_CharacterCount.ClientID %>');
      var count = textBox1.get_textBoxValue().length;
      textBox2.set_value(count);
  }
