Hello,

 You can use 'Page Methods'. Check out the following links for more details:

Hope this helps. 

An Example:

ASPX: 

   <asp:ScriptManager id="ScriptManager1" runat="server" EnablePageMethods="true">
      <Scripts>
        <asp:ScriptReference Path="script.js" />
      </Scripts>
    </asp:ScriptManager>
    
    State Name: <asp:TextBox ID="txtName" runat="server" /><br />
    State Abbr: <asp:TextBox ID="txtAbbr" runat="server" /><br />
    <asp:Button ID="btnInsert" runat="server" Text="Insert" Width="237px" />

Code Behind: 

 
 protected void Page_Load(object sender, EventArgs e)
    {
			btnInsert.Attributes.Add("onclick", "javascript:InsertState('" + txtName.ClientID + "', '" + txtAbbr.ClientID + "')");
    }

	[System.Web.Services.WebMethod]
	public static string InsertState(string name, string abbr)
	{
		try
		{
			using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["CarrierDBConnectionString"].ConnectionString))
			{
				using (SqlCommand cmd = new SqlCommand("INSERT INTO STATE ([NAME],[ABBR]) VALUES (@NAME, @ABBR); SELECT SCOPE_IDENTITY()",conn))
				{
					cmd.CommandType = CommandType.Text;
					cmd.Parameters.AddWithValue("@NAME", name);
					cmd.Parameters.AddWithValue("@ABBR", abbr);

					conn.Open();

					return cmd.ExecuteScalar().ToString();
				}
			}
		}
		catch (Exception ex)
		{
			throw new Exception("Error Inserting Record! " + ex.Message);
		}
	}

JavaScript File:

  
      function InsertState(nameCtrl, abbrCtrl){
        var name = $get(nameCtrl).value;
        var abbr = $get(abbrCtrl).value;
        PageMethods.InsertState(name, abbr, OnSucceeded, OnFailed);
      }     
      
      function OnSucceeded(res){
        alert('Record Inserted! Record Number: ' + res);
      }
      
      function OnFailed(error){
        alert(error.get_message());
      }

Hope this helps =) 

Hi,

There are two approach for achieving it.

1. <%inserting();%> : Put this code into HTML not JavaScript, and it will execute this function.

2. Use doPostBack in JavaScript to trigger a function in CodeBehind.

For example, there is a control Text1.When mouseup will trigger doPostBack:

<input id="Text1" type="text" onmouseup="javascript:__doPostBack('Text1','onmouseup')"/>

 Code Behind:

In Page_Load, it needs to retrieve the doPostBack.

    protected void Page_Load(object sender, EventArgs e)
    {
        if (Request.Params["__EVENTTARGET"] != null)
        {
            string target = Request.Params["__EVENTTARGET"].ToString();

            string passedArgument = Request.Params["__EVENTARGUMENT"].ToString();
            if (target == "Text1" && passedArgument == "onmouseup")
            {
                  inserting();
            }
        }
    }

Hope it helps.
