protected   void  txtIsPaid_CheckedChanged（ object  sender，EventArgs e）
 {
 EmployeeLeave empleave =  new  EmployeeLeave（）; 

 empleave.IsPaid = txtIsPaid.Checked; 

} 

您好，我希望您在txtIsPaid_CheckedChanged事件中没有插入/更新代码



所以请在page_load事件的顶部声明对象empleave（EmployeeLeave empleave = new EmployeeLeave（）;），并在所有事件中使用此对象。



并更改这样的txtIsPaid_CheckedChanged envent

 EmployeeLeave empleave =  new  EmployeeLeave（）; 

受保护  void  Page_Load（对象发​​件人，EventArgs e）
 {
 ///   code 
} 

 protected   void  txtIsPaid_CheckedChanged（ object  sender，EventArgs e）
 {
 empleave.IsPaid = txtIsPaid.Checked; 
} 

请更新，祝你好运，

  protected   void  txtIsPaid_CheckedChanged（ object  sender，EventArgs e）
 {
 //   if（txtIsPaid.Checked == true） 
 //   { 
 EmployeeLeave empleave =  new  EmployeeLeave（）; 
 empleave.IsPaid = txtIsPaid.Checked;  //  不指定文本只分配已检查的属性。 
 //  }  
} 
 //  请同时发布保存值的代码并始终保存为false。 

如果有任何问题请告诉我。

I have a web form in which a check box with code as below

<asp:CheckBox ID="txtIsPaid" runat="server" autopostback="true" OnCheckedChanged="txtIsPaid_CheckedChanged" />

is used.and in sql database datatype is bit.
but when i checked or unchecked this box the value is always false in database. i googled but in vain.

protected void txtIsPaid_CheckedChanged(object sender, EventArgs e)
        {
            if (txtIsPaid.Checked == true)
            {
                EmployeeLeave empleave = new EmployeeLeave();
                empleave.IsPaid = Convert.ToBoolean(txtIsPaid.Text);
            }
        }

protected void txtIsPaid_CheckedChanged(object sender, EventArgs e)
        {
             EmployeeLeave empleave = new EmployeeLeave();

             empleave.IsPaid=txtIsPaid.Checked;
          
        }

Hi, I hope you don't have insert/update code in txtIsPaid_CheckedChanged event

so please declare the object empleave at the top of page_load event (EmployeeLeave empleave = new EmployeeLeave();), and use this object in all events.

and change txtIsPaid_CheckedChanged envent like this

EmployeeLeave empleave = new EmployeeLeave();

protected void Page_Load(object sender, EventArgs e)
{
      /// code
}

protected void txtIsPaid_CheckedChanged(object sender, EventArgs e)
{
      empleave.IsPaid = txtIsPaid.Checked;
}

please update, good luck,

protected void txtIsPaid_CheckedChanged(object sender, EventArgs e)
        {
           // if (txtIsPaid.Checked == true)
            //{
                EmployeeLeave empleave = new EmployeeLeave();
                empleave.IsPaid = txtIsPaid.Checked;//don't assign text just assign checked property.
            //}
        }
//please also post code where you are save value and get saved false always.

if any question then let me know.
