    <p>I have a asp:textbox that allows a user to enter information. When the user clicks the asp:button, it inserts the text from the textbox into my sql database, and then redirects back to the page. If the user hits refresh, the event from the button gets called again. I need to rectify this so that it no longer gets called or it doesn't repost the information. </p> <pre><code>protected void PostButton_Click(object sender, EventArgs e) { if (txtWallPost.Text.Length &gt; 0) { string strCon = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["SocialSiteConnectionString"].ConnectionString; using (SqlConnection conn = new SqlConnection(strCon)) { using (SqlCommand cmd = conn.CreateCommand()) { cmd.CommandText = "INSERT INTO [WallTable] ([UserId], [FriendId], [WallPost]) VALUES (@UserId, @FriendId, @WallPost)"; cmd.Parameters.AddWithValue("@UserId", User.Identity.Name); cmd.Parameters.AddWithValue("@FriendId", User.Identity.Name); cmd.Parameters.AddWithValue("@WallPost", txtWallPost.Text); conn.Open(); cmd.ExecuteNonQuery(); conn.Close(); txtWallPost.Text = ""; LoadWallPosts(); Response.Redirect("~/UserPages/UserProfile.aspx?view="+"wall"); } } } return; } </code></pre>

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.
