I am designing a web form on Visual Studio 2010 using ASP.NET framework. I am using SQL Database to connect my web form to the server, but there are some errors which I can't resolve?
Any help would be greatly appreciated.
I am trying to run a web form that connects to the database which when data entered into the form, stores the information into the server for the user to login later
The following is the code for the web form.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
public partial class _Default : System.Web.UI.Page
{
SqlConnection con = new SqlConnection(#"Data Source=.\SQLEXPRESS;AttachDbFilename=#"C:\Users\Kapalmeet Singh\Desktop\WebSite1\App_Data\Database.mdf";Integrated Security=True;User Instance=True")
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
con.Open();
SqlCommand cmd = con.CreateCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "insert into Table1 values('"+TextBox1.Text+"','"+TextBox2.Text+"','"+TextBox3.Text+"','"+TextBox4.Text+"')";
cmd.ExecuteNonQuery();
con.Close();
}
}
And here's the code for the web form

If your creating a registration it would be like this. Change the names for these the way they are called in your database and for the other ones to. (#FirstName, #Surname, #Password, #Username,)
protected void Button1_Click(object sender, EventArgs e)
{
try
{
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["YOUR_CONNECION_STRING_HERE"].ConnectionString);
conn.Open();
string insertQuery = "insert into Table1(FirstName, Surname, Username, Password) " +
"values(#FirstName, #Surname, #Password, #Username,)";
SqlCommand com = new SqlCommand(insertQuery, conn);
com.Parameters.AddWithValue("#FirstName", Textbox1.Text);
com.Parameters.AddWithValue("#Surname", Textbox2.Text);
com.Parameters.AddWithValue("#Password", Textbox3.Text);
com.Parameters.AddWithValue("#Username", Textbox4.Text);
//This actually executes the query with the given values above.
com.ExecuteNonQuery();
conn.Close();
Response.Redirect("Name_Of_Any_Page_Thats_On_Your_Site.aspx");
Response.Write("there was a problem with your registration");
}
catch (Exception problem)
{
//throw Exception ;
Response.Write("Error Message: " + problem.ToString());
throw;

I noticed that you have specified Step1 class name as Inherits attribute. Ensure that it matches the class name in your Step9.aspx.cs file. I guess Step9 but just confirm.

Question:
When I do not select in ddlProvince why when u save it to database it shows an error Input string was not in a correct format.
It throws "Input string was not in a correct format" error because you are trying to convert null to Int.
cmd.Parameters.Add("#ProvinceId", SqlDbType.Int).Value = Convert.ToInt32(ddlProvince.SelectedValue);
You can check whether SelectedValue is null before converting it to Int as below.
cmd.Parameters.Add("#ProvinceId", SqlDbType.Int).Value = (ddlProvince.SelectedValue == null) ? null : Convert.ToInt32(ddlProvince.SelectedValue)

Email Varchar(50)
There are a host of options in the jQuery field:
jQueryUI's dialog
Wijmo's Dialog
SimpleModal
If you'd already using jQuery, jQueryUI's option may be a good fit. Wijmo is also jQueryUI compatible/friendly (use the same theme CSS class names and patterns), so it's also a good fit.
So it kind of depends on what you want. Something very simple - maybe jQueryUI. Flashy/pretty -- SimpleModal. More complex but jQueryUI-friendly - Wijmo.
I am new to ASP.NET, I am making a search box in my application.
For example: if a user enters "abc" in the textbox, then the textbox will fetch data from the database which starts with "abc". I am passing this data to DataTable.
It works properly,
Here is my code snippet:
DataTable result = new DataTable();
protected void TextBox1_TextChanged(object sender, EventArgs e)
{
connString = System.Configuration.ConfigurationManager.ConnectionStrings["MyConsString"].ConnectionString;
SqlConnection conn = new SqlConnection(connString);
conn.Open();
string query = string.Format("SELECT DISTINCT Scrip FROM dbo.SearchBoxData where Scrip Like '{0}%'", TextBox1.Text);
SqlCommand cmd = new SqlCommand(query, conn);
result.Load(cmd.ExecuteReader());
conn.Close();
lvwItems.DataSource = result;
lvwItems.DataBind();
}
Now I want to retrieve all this data in my <div> tag. so i tried using asp:ListView,
here is my code snippet,
it works properly, but now i want to navigate to new page when user select any row of listView, but i am unable to select any row..
<asp:ListView ID="lvwItems" runat="server" ItemPlaceholderID="plhItems">
<LayoutTemplate>
<div>
<asp:PlaceHolder ID="plhItems" runat="server"></asp:PlaceHolder>
</div>
</LayoutTemplate>
<ItemTemplate>
<div>
<%# Eval("Scrip")%>
</div>
</ItemTemplate>
Thanks In Advance !!

You have to add a SELECT button in the ItemTemplate, see the complete working code.
<asp:ListView ID="lvwItems" OnSelectedIndexChanging="lvwItems_SelectedIndexChanging"
runat="server" ItemPlaceholderID="plhItems">
<LayoutTemplate>
<div>
<asp:PlaceHolder ID="plhItems" runat="server"></asp:PlaceHolder>

</ItemTemplate>
</asp:ListView>
protected void lvwItems_SelectedIndexChanging(Object sender, ListViewSelectEventArgs e)
{
ListViewItem item = (ListViewItem)lvwItems.Items[e.NewSelectedIndex];
Label lablId = (Label)item.FindControl("CONTROL_ID");
}
Thanks

Probably you will have to add the event for Selected index change:
<asp:ListView ID="lvwItems" runat="server" ItemPlaceholderID="plhItems" OnSelectedIndexChanging="lvwItems_SelectedIndexChanging">
In code behind you can get the selected row item like below.
Also you can place a label or hidden field so that you can get some data from those control and pass it in to the next page.. (might be id or something).
<asp:ListView ID="lvwItems" OnSelectedIndexChanging="lvwItems_SelectedIndexChanging"
runat="server" ItemPlaceholderID="plhItems">
<LayoutTemplate>
<div>
<asp:PlaceHolder ID="plhItems" runat="server"></asp:PlaceHolder>
</div>
</LayoutTemplate>
<ItemTemplate>
<div>
<%# Eval("Scrip")%>
<asp:Label ID="lablId" visible="flase" runat="server" Text='<%#Eval("Id") %>' />
</div>
</ItemTemplate>
</asp:ListView>
void lvwItems_SelectedIndexChanging(Object sender, ListViewSelectEventArgs e)
{
ListViewItem item = (ListViewItem)lvwItems.Items[e.NewSelectedIndex];
Label lablId = (Label)item.FindControl("lablId");
if (String.IsNullOrEmpty(lablId.Text))
{
Response.Redirect("page.aspx?id="+lablId.Text,false);
}
}
Thanks
Deepu
Here you go,
Also remove the OnClick="callMethod" from the button. Since you have SelectedIndex method no need to have the onClick method.
protected void lvwItems_SelectedIndexChanging(Object sender, ListViewSelectEventArgs e)
{
ListViewItem item = (ListViewItem)lvwItems.Items[e.NewSelectedIndex];
Button btn = (Button)item.FindControl("btn1");
if(btn != null)
{
var buttonText = btn.Text;
}
}
Hope this helps
Thanks
