I dont want this null value “& nbsp;” to be displayed inside Textboxes, It has to be be empty when i select from Gridview… What i have to do for that?

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);
    }
