将varchar值'System.Web.UI.WebControls.CheckBox'转换为数据类型位时转换失败

when i check on checkbox whose datatype is bit ,its value i.e 1 or 0 is not being store in database it is giving error

当我检查其数据类型为bit的复选框时，其值（即1或0）未存储在数据库中，它给出了错误

Conversion failed when converting the varchar value 'System.Web.UI.WebControls.CheckBox' to data type bit

将varchar值'System.Web.UI.WebControls.CheckBox'转换为数据类型位时转换失败

if (CheckBoxDT.Checked) 
{ 
    cmd.CommandText = " Insert into ClientMaster(doTips) values ( 1 )";    
    cmd.Parameters.AddWithValue("doTips", bool.Parse("1")); 
    cmd.ExecuteNonQuery(); 
} 
else 
{ 
    cmd.CommandText = "insert into ClientMaster(doTips) values (0)";
    cmd.Parameters.AddWithValue("doTips", bool.Parse("0")); 
    cmd.ExecuteNonQuery(); 
} 

3 个解决方案

#1

Inserting Bit value to the database

将位值插入数据库

  cmd.Parameters.Add("@check", SqlDbType.Bit).Value = Convert.ToInt16(CheckBoxDT.Checked);

retrieving selected check boxes Try this

检索选中的复选框试试这个

<asp:CheckBox ID="CheckBoxDT" runat="server" Checked='<%#((bool)Eval("isActive"))%>'
                        Style="color: #FFFFFF" />

Your code

你的代码

if (CheckBoxDT.Checked) 
{ 
cmd.CommandText = " Insert into ClientMaster(doTips) values ( 1 )";    
cmd.Parameters.AddWithValue("doTips", bool.Parse("1")); 
cmd.ExecuteNonQuery(); 
} 
else 
{ 
cmd.CommandText = "insert into ClientMaster(doTips) values (0)"; 
cmd.Parameters.AddWithValue("doTips", bool.Parse("0")); 
cmd.ExecuteNonQuery(); 
}

Replace this with

替换为

cmd.CommandText = "insert into ClientMaster(doTips) values (@doTips)"; 
cmd.Parameters.Add("@doTips", SqlDbType.Bit).Value = Convert.ToInt16(CheckBoxDT.Checked)
cmd.ExecuteNonQuery();

Chances are you're passing the control, rather than the value of its state; you should be passing the state, and converting that explicitly if necessary:

你有可能通过控制，而不是其状态的价值;你应该传递状态，并在必要时明确转换它：

CheckBox         // a web control, and no standard db type to represent it
CheckBox.Checked // a boolean value, generally translatable to db bit

#3

You are most probably passing the actual control to your database and not the state of it. You need to use myCheckBox.Checked instead of just myCheckBox.

您很可能将实际控件传递给数据库而不是它的状态。您需要使用myCheckBox.Checked而不仅仅是myCheckBox。
