I'm using detailsview in asp.net. I have gender field. when this field checked, checkbox text automatically changed to 'male', otherwise 'female'. How can i do? How to setup checkbox to this feature?

From stackoverflow

• While I hope you aren't actually doing this, the following will accomplish it:

  protected void chkSex_CheckedChanged(object sender, EventArgs e)
  {
      CheckBox chkSex = (CheckBox)sender;
      chkSex.Text = SexString(chkSex.Checked);
  }
  protected string SexString(bool sex)
  {
      return sex ? "Male" : "Female";
  }
  

  And the markup:

  <asp:UpdatePanel runat="server">
      <ContentTemplate>
          <asp:CheckBox runat="server" 
              Checked='<%# Eval("Sex") %>'
              OnCheckedChanged="chkSex_CheckedChanged" 
              AutoPostBack="true" 
              Text='<%# SexString((bool)Eval("Sex")) %>'/>
      </ContentTemplate>
  </asp:UpdatePanel>
  

• You can do this with some simple javascript.

  Mark Up

  <label id="sexLabel" for="sexCheckBox">Male</label>
  <input id="sexCheckBox" type="checkbox" onclick="sexClick(this);" />
  

  Code

  function sexClick(checkbox) {
      document.getElementById('sexLabel').innerHTML = (checkbox.checked) ? 'Female' : 'Male';     
  }
  

  jQuery

  Mark Up

  <label id="sexLabel" for="sexCheckBox">Male</label>
  <input id="sexCheckBox" type="checkbox" />
  

  Code

  $(function() {
      $('#sexCheckBox').click(function() {
          $('#sexLabel').text((checkbox.checked) ? 'Female' : 'Male');
      });
  });
  

  Yuriy Faktorovich : Ha, I went overboard.

• Suppose the column or property name is Sex and is true if sex is male. Use this in markup:

  <asp:CheckBox runat="server" ID="chkSex" Text='<%# GetText((bool)Eval("Sex"))%>' 
           Checked='<%# Eval("Sex")%>' />
  

  write this method in code-behind:

  protected static object GetText(bool b)
  {
      return b ? "Male" : "Female";
  }
