Create FilteredTextBoxExtender in ListView RRS feed

  • Question

  • User1510859543 posted

    Is it possible to dynamically remove a FilteredTextBoxExtender at runtime?  I have one in a ListView and when I try to export the html of the listview I get an error so I would like to dynamically remove it while exporting.  Thanks.

    Can you please explain what you are trying to do in detail?

    I couldn't understand your question. The title of thread and question is conflicting.

    if you want to Create FilteredTextBoxExtender, you can check out the link below:

    adding programatically FilteredTextBoxExtender


    if you want to remove it while exporting, you need to find FilteredTextBoxExtender control in code-behind, then remove it from ListView:

    using AjaxControlToolkit;

    ListViewItem item  = ddlReason.NamingContainer as ListViewItem;
     FilteredTextBoxExtendertbox = item.FindControl("txtOtherReason") as FilteredTextBoxExtender;

    Hope it helps you.

    Yes, I want to have the FilteredTextBoxExtender removed when I export the ListView but then re-created when the user goes back into edit or insert mode.  I could not find a "Visible" property so I thought that was my only choice.  Am I correct?

    No, i don't agree with you.As usual we replace "Visible" property with 'dipaly:none' , for example:

      <div style="display:none" >
    <asp:TextBox ID="TextBox1" runat="server" /> <ajaxToolkit:FilteredTextBoxExtender ID="FilteredTextBoxExtender5" runat="server" TargetControlID="TextBox1" FilterType="Numbers" /></div>

    check out codes above, you can hide your FilteredTextBoxExtender control.

    Of course you can also hide them by code behind, add the style for them Dynamicly.

    Hope it can inspire you. if it is not helpful , you can post the complete  markup or provide a simple demo,which can easily reproduce the problem.

    Thank you for your understanding.

    I tried this concept before but it didn't work because the export process still found the control and threw an error. If I set visible to False then the export of the ListView worked great.
