Hi,

I am new to asp.net.and this question seems pretty silly, but I really can't figure out what is wrong.

I am having an issue with clearing the textbox.
I tried textbox.text=string.empty, textbox.text="" but none of these seem to help, the textbox just doesn't get cleared.

Can someone tell me if I have set something in the code that's not allowing me to clear the textbox?

[Edit: added code snippet from comments below - Henry]

XML

<asp:TextBox ID="TextBox3" runat="server" Width="177px" ontextchanged="TextBox3_TextChanged" Height="16px" style="margin-left: 5px"></asp:TextBox>

C#

protected void Button11_Click(object sender, EventArgs e)
{
  Panel1.Visible = false; DropDownList5.ClearSelection();
  TextBox3.Text = string.Empty;
}

Could you provide the code that you use? Specifically, we would like to see the html tag that defines your textbox, and the code behind that you are calling(Where your textbox.text=string.Empty) would be found, for example. It would make providing an answer much easier as the methods you describe should work if implemented properly.

What is happening in your ontextchanged handler? It may be part of the issue.

Hi Gowri,

if you give first priority for below code,

Panel1.Visible = false;

then upcoming inner part will not work.

so, if you want panel visible is false, then use after it.

The letter i seems to be stuck on your keyboard, do something about it.

what you mean?

Read all the other answers before putting your own down. The point here is not to provide answers that already exist, but only to answer with information that has not yet been provided.

Tarun.K.S 16-Aug-11 14:23pm

What Manfred meant to say is, a simple Hi with one "i" is enough. And avoid using trailing dots like this ".....". Use the <pre> tags to wrap your code, its more readable. Also avoid saying "u", "y" instead of you and why, its called text speak and is not at all tolerated, atleast here. Keep these things in mind, it will help you in the long run.
