    <p>I think it's the way you are inserting the items into the database since you said that it disables the button but doesn't insert the database. So to me, that means the event is firing but something is wrong with the way you are inserting. This is how my buttons look, using your code..</p> <pre><code>protected void Button2_Click(object sender, EventArgs e) { string person = droplist_person.SelectedItem.Text; string item = txt_stuff.Text; string expdate = DateTime.Now.ToString(); string price = txt_price.Text; System.Threading.Thread.Sleep(500); SqlConnection con = new SqlConnection("Data Source=DTPXP-77A;Initial Catalog=practice;Integrated Security=true"); con.Open(); SqlCommand cmd = new SqlCommand("INSERT INTO (expense person, item, expdate, price) VALUES (@person, @item, @expdate, @price)", con); cmd.Parameters.AddWithValue("@person", person); cmd.Parameters.AddWithValue("@item", item); cmd.Parameters.AddWithValue("@expdate", expdate); cmd.Parameters.AddWithValue("@price", price); cmd.ExecuteNonQuery(); InsertHistory(); Response.Redirect("Add.aspx"); Button2.Enabled = false; //you can disable the button one the button click as well. Page.ClientScript.RegisterStartupScript(this.GetType(), "Call my function", "mess();", true); } </code></pre> <p>I would also surround that in a try/catch. Also, as far as I know, the Add is the "old" way of inserting items into the database. AddWithValue is going to be the best way since you are inserting items from drop downs and from text boxes. I think this is the where the problem lies. You can also put the connection inside the connection inside the SqlConnection like above to "clean" things up a bit. As to your "2nd" question, I'm not completely sure what you mean, but I hope this solves the problem to your 1st question.</p> <p>EDIT: Added the disabling of the button since it was described in the title. </p> <p>EDIT 2: Also, remove the UseSubmitBehavior="false" and the OnClientClick. Instead, you can call the message in the behind code.. Look above for example. </p> <p>EDIT 3: From what I understand then, you will want to keep what the code the inserts the values. So keep the OnClientClick = "return Validate();" And then in your button click, disable the button. Then you will want to add if(!PostBack) to the page load, like so.. This will enable the button on the page load if the postback has happened. So what will be happening is that you disable the button, then once it posts back, it will be re-enabled. </p> <pre><code>protected void Page_Load(object sender, EventArgs e) { if(!IsPostBack) { Button2.Enabled = true; } } </code></pre>

    1. COCheck the updated code above. Actually 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.

    2. COActually when I write OnClientClick= "return Validate();this.disabled=true" then values are submitted but button is not disabled but if I just reverse it OnClientClick= "this.disabled=true;return Validate()" then button is disabled but value isn't submitted.

    3. COCould you disable the button in the behind code? That would be an easy solution I think.

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.
