Re: Textchanged event is not working in VS 2010

What Error ur getting....? Can u plz show ur code ?

Re: Textchanged event is not working in VS 2010

you need to place the textbox in a updatepanel and set autopostback=true for the textbox

Re: Textchanged event is not working in VS 2010

Hi,

Hope you have marked AutoPostback="true" for that textbox. still not worked then please let us know your code so we can help you better.

Re: Textchanged event is not working in VS 2010

hi Neiteen,

Not working in the sence, is it not firing..?

Please check whether u have mentioned AUTOPOSTBACK="TRUE"...

Re: Textchanged event is not working in VS 2010

You might not have set Autopostback to true and make sure CausesValidation is false once you set autopostback to true to prevent validation on the TextChangedEvent trigger

Re: Textchanged event is not working in VS 2010

Hi,

as above said check for auto postback true for the textbox. if its there on that case check for the form tag of the page ther should not be multiple form tag.

Re: Textchanged event is not working in VS 2010

thanks to all for quick reply.. My code is very simple I have textbox & one label..on TextChanged event label text should changed....

It is not goin to event while debugging....

protected void TextBox1_TextChanged(object sender, EventArgs e)
    {
        Label1.Text = "test";
    }

Re: Textchanged event is not working in VS 2010

Autopostback is true...& CausesValidation is false...but still it is not working..

Re: Textchanged event is not working in VS 2010

protected void TextBox1_TextChanged(object sender, EventArgs e)
    {
        Label1.Text = "test";
    }

Re: Textchanged event is not working in VS 2010

since no postback is required actually( i mean if nothing should go to server or come back to browser), use javascript to achieve this

Re: Textchanged event is not working in VS 2010

Hi Neiteen

Please show me your HTML code for the textbox... and if you are using the Updatepanel then please show the same also.

Re: Textchanged event is not working in VS 2010

Hope you place runat="server" to the textbox control.

Please verify once.

Re: Textchanged event is not working in VS 2010

Hi Neiteen

Please check with the below code as HTML

<table>
    <tr>
        <td>
            <asp:TextBox id="txt" AutoPostBack="true" runat="server"></asp:TextBox>
        </td>
        <td>
            <asp:Label ID="lbl" runat="server"></asp:Label>
        </td>
    </tr>
   </table>

and below as code behind code

 protected void Page_Load(object sender, EventArgs e)
    {
        txt.TextChanged += new EventHandler(txt_TextChanged);
    }

    void txt_TextChanged(object sender, EventArgs e)
    {
        lbl.Text = txt.Text;
    }

This will surely work for you.
