Remove text from text box on click

Question

User810354248 posted

I have a text box in my asp.net+VB=SQL database web.

bidtxt.text is the textbox name.

I use barcode scanner to insert the id to serach the data in bidtxt.text

i wanted to remove the text inside the text box on another search.  I used the below code.

<asp:TextBox ID="bidtxt" onChange="newobjCompute()" onFocus="this.value=''; return false;" runat="server" Width="300px" ToolTip="Box ID" AutoPostBack="True"></asp:TextBox>

It works only when i ckick  on any other area in page and again click on text box it gets deleted.

But i am not using any other option in this page. I want to search with barcode scanner and on another clikc on search the text box should be empty.

any more idea on this

Why not simply set tb.text = "" after search? You can display current id in a label or hiddenfield

Hi Baiju EP,

According to your description, I suggest you could firstly search the barcode scanner library to find out the which method will fired when scan complete.

Then you could write the logic wiht textbox.text="" to remove the textbox and add value into it.
