Answer 1

How about (btw i am using a stored procedure)

Code behind

cmd.Parameters.Add("@p_facebook", SqlDbType.Bit).Value = social_facebook.Checked;

Answer 2

Solution:

Hi, I'm also using Ajax rating inside a GridView and I ran into this problem. After looking through several forums, I tried this and it worked for me. I hope it helps you:

<%# Convert.ToInt32(Eval("EVALUATION")) %>

returns an integer, since you're using Checked which is an integer.

Answer 3

If you're willing to change the class, add a property on the class that's a boolean

public bool IsUploadedBoolean
{
   get { return IsUploaded != 0; }
   set { IsUploaded = value ? 1 : 0; }
}

If not, you may have success with a TypeConverter:

1. Create a custom TypeConverter which will handle 0 and 1 to boolean conversions
2. Stick the TypeConverterAttribute on the IsUploaded property to direct .NET to your custom typeconverter.

Answer 4

Kind of a cheesy work around would be to use a drop down list with list items to give the same effect:

<asp:DropDownList ID="ddlBool" runat="server" SelectedValue= '<%# Bind("IsUploaded") %>'>
    <asp:ListItem Text="True" Value="1" />
    <asp:ListItem Text="False" Value="0" />
</asp:DropDownList>

Answer 5

How about adding a property to your class which does the conversion?

public bool IsUploadedBool
{
  get { return IsUploaded == 1; }
}

and then bind to this IsUploadedBool property instead of directly to the underlying INT.
