If you are using DataSource controls, then set ConvertEmptyStringToNull="true" to your parameters

    <InsertParameters>
        <asp:ControlParameter ConvertEmptyStringToNull="true" />
    </InsertParameters>

OR if you are using parameterized query then it should be like...

if (TextBox1.Text.Trim() = string.Empty)
    {
        // pass the null value as parameter
        //com.Parameters.AddWithValue("@savePath", null);
    }

After assigning value to your TextBox from GridView write the following code:

    if(textBoxName.Text == "& nbsp;")
    {
        textBoxName.Text = Server.HtmlDecode(textBoxName.Text);
    }
