How do I save data into MySql database using ASP.NET - asp.net

Question

I am trying to insert data into MySql database but I am not getting any errors. I have already tested out the sql query but it works in the mysql workbench but it not working in the project codes.
protected void uploadImagesBtn_Click(object sender, EventArgs e)
{
String connString = System.Configuration.ConfigurationManager.ConnectionStrings["CMSconnectionString"].ToString();
string name = ImgNameTB.Text;
string desc = imgDescriptionTB.Text;
string date = uploadDateTB.Text;
string constr = ConfigurationManager.ConnectionStrings["CMSconnectionString"].ConnectionString;
using (MySqlConnection con = new MySqlConnection(constr))
{
using (MySqlCommand cmd = new MySqlCommand("INSERT INTO fyp_cms.images (ImageName, ImageDescription, UploadDate) VALUES (#imgname, #imgdesc, #imgUploadDate)"))
{
using (MySqlDataAdapter sda = new MySqlDataAdapter())
{
cmd.Parameters.AddWithValue("#imgname", name);
cmd.Parameters.AddWithValue("#imgdesc", desc);
cmd.Parameters.AddWithValue("#imgUploadDate", date);
cmd.Connection = con;
con.Open();
cmd.ExecuteNonQuery();
con.Close();
}
}
}
}

</div>
<asp:Button ID="uploadImagesBtn" runat="server" class="btn btn-primary" Text="Upload" OnClick="uploadImagesBtn_Click" />
</div>
Those above are my codes, I am not sure what is the error as I have alr added an onclick function on the upload button

Answer 1

set form Post,enctype and button type Submit.
actually you are submitting file. form is not submitting without form enctype
<form method="post" enctype="multipart/form-data">
<asp:Button ID="uploadImagesBtn" type="submit" runat="server" class="btn btn-primary" Text="Upload" OnClick="uploadImagesBtn_Click" />
