    <p>I've a Validate function and it returns true and false depending upon the inserted values. I want to validate as well as disable the submit button. for ex OnClientClick = "return Validate(this);" if it returns true, submit into database and disable submit for that period of time and if it is false disable submit and alert with the validate message.</p> <pre><code>&lt;script type="text/javascript"&gt; function Validate(b) { function stuff() { var temp = document.getElementById("&lt;%=txt_stuff.ClientID %&gt;").value; var val = /^[a-zA-Z0-9 ]+$/ if (temp == "") { alert("Please Enter Stuff"); return false; } else if (val.test(temp)) { return true; } else { alert("Name accepts only spaces and charcters"); return false; } } function price() { var temp2 = document.getElementById("&lt;%=txt_price.ClientID %&gt;").value; var val2 = /^[0-9 ]+$/ if (temp2 == "") { alert("Please Enter Price"); return false; } else if (val2.test(temp2)) { return true; } else { alert("Price accepts only Number"); return false; } } if (stuff() &amp;&amp; price()) { b.disabled = true; b.value = 'Submitting...'; return true; } else { return false; } } &lt;/script&gt; </code></pre> <p>Here is the button code</p> <pre><code> &lt;asp:Button ID="Button2" runat="server" Text="Add Record" OnClientClick = "return Validate(this)" onclick="Button2_Click" /&gt; </code></pre> <p>The button gets disabled but the value isn't submitted into the database and the button also doesn't get enabled again. What could be the reason?</p> <p>Database code is </p> <pre><code>protected void Button2_Click(object sender, EventArgs e) { System.Threading.Thread.Sleep(500); SqlConnection con = new SqlConnection(); con.ConnectionString = "Data Source=DTPXP-77A;Initial Catalog=practice;Integrated Security=true"; con.Open(); SqlCommand cmd = new SqlCommand("insert into expense values(@person,@item,@expdate,@price)", con); cmd.Parameters.Add("@person", SqlDbType.VarChar); cmd.Parameters.Add("@item", SqlDbType.VarChar); cmd.Parameters.Add("@expdate", SqlDbType.DateTime); cmd.Parameters.Add("@price", SqlDbType.Int); cmd.Parameters["@person"].Value = droplist_person.SelectedItem.ToString(); cmd.Parameters["@item"].Value = txt_stuff.Text; cmd.Parameters["@expdate"].Value = DateTime.Now.ToString(); cmd.Parameters["@price"].Value = txt_price.Text; cmd.ExecuteNonQuery(); InsertHistory(); Response.Redirect("Add.aspx"); } </code></pre>

    1. COWithout actual code part nobody can tell you what is going on. Post the part where you make database query, for example.

    3. COReasons may be many. First of all are you sure the connection is made with the SQL Server (is it online)? Second, check if parameters have valid values for the Database. I would suggest to turn on the debugger and start it. You will face an exception if error had occurred. F10 is step over F11 is step-into. However, **I suspect `SqlDbType.DateTime` may differ from `Datetime.ToString`** - will expect different input.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
