为什么我的服务器端代码没有在 ASP.net 按钮点击时触发？

Question

I don't understand why my server side is not executed.

Here is my code

ASP code

<div class="row" style="padding-top:20px;">
    <div class="col-lg-4">
        <input id="btnSave" type="button" class="btn btn-info"  value="Save" />
        <input id="btnLoad" type="button" class="btn btn-info"  value="Load" />

         <%-- SAVE DIALOG  --%>
         <div id="saveDialog" title="Basic dialog">
         <div class="row">
             <div class="col-lg-4">
                 <asp:Label ID="lblFileName" CssClass="control-label" runat="server" Text="File Name"></asp:Label>
             </div>
             <div class="col-lg-6">
                 <asp:TextBox ID="txtFileName" CssClass="form-control" runat="server"></asp:TextBox>
             </div>
         </div>
         <div class="row">
             <div class="col-lg-12" style="text-align:center;">
                 <asp:Label ID="lblSaveErrorMsg" runat="server" Text="" ForeColor="Red"></asp:Label>
             </div>
         </div>
         <div class="row" style="padding-top:10px;">
             <div class="col-lg-12" style="text-align:center;">
                <asp:Button ID="btnSaveFile" runat="server" Text="Save" OnClick="btnSaveFile_Click"/>
                                
             </div>
         </div>
     </div>                   
</div>

Server Side Code

protected void btnSaveFile_Click(object sender, EventArgs e)
    {
        string cs = ConfigurationManager.ConnectionStrings["xxx"].ConnectionString;

        using (SqlConnection con = new SqlConnection(cs))
        {
            byte[] byteArray = Encoding.UTF8.GetBytes(ASPxPivotGrid1.SaveLayoutToString());
            MemoryStream stream = new MemoryStream(byteArray);

            DateTime currentDate = DateTime.Now;

            SqlCommand cmd = new SqlCommand();
            cmd.Connection = con;
            cmd.CommandText = "INSERT INTO ReportSave(UserID,ReportName,UserFileName,ReportData,Time,ReportFilter)VALUES(@UserID,@ReportName,@UserFileName,@ReportData,@Time,@ReportFilter);";
            
            cmd.Parameters.AddWithValue("@UserID", UserID);
            cmd.Parameters.AddWithValue("@ReportName", ReportName);
            cmd.Parameters.AddWithValue("@UserFileName", txtFileName.Text);
            cmd.Parameters.AddWithValue("@ReportData", stream);
            cmd.Parameters.AddWithValue("@Time", currentDate);
            cmd.Parameters.AddWithValue("@ReportFilter", txtFilterRecord.Text);

            con.Open();
            cmd.ExecuteNonQuery();

            //string message = "Your details have been saved successfully.";
            //string script = "window.onload = function(){ alert('";
            //script += message;
            //script += "')};";
            //ClientScript.RegisterStartupScript(this.GetType(), "SuccessMessage", script, true);
        }
    }

Note:

It doesn't show any error message and it is not reloading the page as well. It was weird.

I call jquery functions, after it execute also it never call the server code. For testing purpose, I removed the entire jquery code for this button. So no Jquery function for this button now. But still I couldn't call the server side code why???

UPDATED

I found something, I have one button on the form called btnSave , once user click it will call

$('#btnSave').click(function () {
    $('#saveDialog').dialog();
});

IMPORTANT NOTE: Then Dialog box will appear. In that dialog box I have added that button btnSaveFile . But When I add this button outside the dialog, it's calling the server side code.

Hey friend protected void btnSaveFile_Click(object sender, EventArgs e) copied this method from other page or application then it will not work, So delete the event and event name assigned to the button. Go to design and go to button even properties go to OnClick event double click it, It will generate event and automatically assigns event name to the button. It will work.

Or

Give the new Onclick function name in the code

<asp:Button ID="btnSaveFile" runat="server" Text="Save" OnClick="btnSaveFile_Click"/>

You may use this code in Jquery:

$(document).on('click', '#btnSave', function() {
{
   $('#saveDialog').dialog();
});
