I am developing a little project for a local school and I am pretty much what you can call a newbie in programming.
I am trying to retrieve a selected date by the user in the calendar to save to a separate database. I have an Entity Framework model (.edmx) to link the table in Visual Studio that I need.

.cs File:
protected void ButtonSubmit_Click(object sender, EventArgs e)
{

iPadLoanEntities db = new iPadLoanEntities();
db.tblProjectors.Add(entry);
db.SaveChanges();
}
protected void Calendar1_SelectionChanged1(object sender, EventArgs e)
{
Calendartxt.Text = Calendar1.SelectedDate.ToShortDateString();
}
}
I am constantly getting an error saying validation for one or more than one entities failed. Also the error points to the line of code:
db.SaveChanges();
I know that with that code I am trying to get the information of the TextBox that is linked to the calendar to be saved to the database but to be honest saving it directly from the calendar would be great if it is possible.
If anyone could give me a hand on how to be able to achieve this I would be grateful. Thanks

I've added the update panel. So far from my research, I know that we should use update panel to prevent the page jump up when auto post back. However, mine does not work. Any guides?
Thanks in advance.
You can use the MaintainScrollPositionOnPostback attribute of page Directive. See Sample below:
<%# Page MaintainScrollPositionOnPostback="true" %>
I have an asp.net page with a c# code-behind. I am trying to have the code-behind display an 'alert' if the selected-index of a gridview object is changed without selecting 'confirm' or 'cancel'. The code for detecting if confirm or cancel was selected is working, however my message is never displayed. The 'Alert.Show" code was borrowed from: http://archive.devnewz.com/devnewz-3-20061129JavaScriptAlertShowmessagefromASPNETCodebehind.html .
Alert.show works just fine when tested from the page_load(), for example, but not in my selected_index_changed method. Any idea why? Perhaps having to do with how Alert.Show() is implemented?
if (ChangeAttemptedId && !IsSavedId)
{
Alert.Show("Dispatch assignment saved, but you forgot to click Confirm or Cancel!)");
}

Description
Assuming i understand your question.
You can use the ScriptManager to show a javascript alert message.
Sample
protected void Page_Load(object sender, EventArgs e)
{
ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(),
"err_msg",
"alert('Dispatch assignment saved, but you forgot to click Confirm or Cancel!)');",
true);
}
More Information
MSDN - ClientScriptManager.RegisterStartupScript Method
private void MessageBox(string message,string title="title")
{
ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), title, "alert('" + message + "');", true);
}
It can be useful:
http://www.codeproject.com/Questions/311503/How-to-use-javascript-alert-message-in-code-behind
If you want a single piece of client-side JavaScript to run when the page loads, you can register a startup script in your code-behind:
if(!ClientScript. IsStartupScriptRegistered(typeof(Page), "alert"))
string script = "<script>";
script += "alert('";
script += "Dispatch assignment saved, but you forgot to click Confirm or Cancel!";
script += "');";
script += "</script>";
ClientScript.RegisterStartupScript(typeof(Page), "alert", script);
}
ASP.NET will take care of putting the <script> in your HTML and calling it when the page is loaded.
Your asp:ListBox must have AutoPostBack="True" if the selected_index_changed event should be raised by changing index.
for example
<asp:ListBox ID="ListBox1" runat="server"
AutoPostBack="True" OnSelectedIndexChanged="selected_index_changed">
<asp:ListItem>one</asp:ListItem>
<asp:ListItem>two</asp:ListItem>
<asp:ListItem>three</asp:ListItem>
</asp:ListBox>'
public static void Alert(string message,Page page)
{
ScriptManager.RegisterStartupScript(page, page.GetType(),
"err_msg",
"alert('" + message + "');",
true);
}
I'm trying to get the value from detailsview to formview. I want to set the Book ID/ISBN in formview insert textbox to Book ID/ISBN value from detailsview.
Here's a sample of my code:
<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False"
CellPadding="4" DataKeyNames="bookid" DataSourceID="detailsDataSource"
ForeColor="#333333" GridLines="None" Height="50px" Width="">
<FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<CommandRowStyle BackColor="#D1DDF1" Font-Bold="True" />
<RowStyle BackColor="#EFF3FB" />
<FieldHeaderStyle BackColor="#DEE8F5" Font-Bold="True" />
<PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
<FooterTemplate>
<asp:GridView ID="GridView2" runat="server" AllowPaging="True"
AllowSorting="True" AutoGenerateColumns="False" CellPadding="4"
DataKeyNames="reservationid" DataSourceID="reserveDataSource"

So what I'm trying to do is when a user click the Insert/Reserve book linkbutton the Book ID/ISBN is already set to the Book ID/ISBN in formview insert mode as default.
Any help would be much appreciated ;)
Thanks in advance.
Can you try and check the DetailsView1.SelectedValue
<asp:TextBox ID="bookidTextBox" runat="server"
Text='<%# DetailsView1.SelectedValue %>'/>
Edit:
Now if you want to bind that value to your Insert function of your DetailsView, it will not behave like the other control, since you are using the Bind method for the other control and it provides two way binding.
Now you need to pass that value to inserting evet of DetailsView like as we are assigning values using DetailsView1.SelectedValue but not binding the value.
I hope you understand this theory.
protected void DetailsView1_ItemInserting(object sender, DetailsViewInsertEventArgs e)
{
e.Values["bookid"] = ((TextBox)DetailsView1.FindControl("bookidTextBox")).Text;
}
