GridView Disappears on Update Button Click, Doesn't Update Record

So I have a c# page with a GridView. For some reason, after adding the label and the template for editing, when I click the update button in the edit column, the GridView disappears and none of the records get changed. I know I need to databind the values in the edit box once the user clicks update but I'm not sure how. Can anyone give any suggestions?
Here is my code.
public partial class CMSWebParts_Custom_Development_DevWebPart :
CMSAbstractWebPart
{
public string paramId;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
ViewState["RefUrl"] = Request.UrlReferrer.ToString();
}
string urlString = Request.UrlReferrer.ToString();
paramId = HttpUtility.ParseQueryString(urlString).Get("Theid");
DispatchNumberLabel.Text = getDispatchNumber();
//TerminalLabel.Text = getTerminal();
DispatchInfoIdLabel.Text = getDispatchInfoId();
DriverNameLabel.Text = getDriverName();
}
protected string getDispatchInfoId()
{
string result = DriverDropDownList.SelectedValue;
return result;
}
protected string getDispatchNumber()
{
string result = paramId;
return result;
}
protected string getTerminal()
{
string result;
string connectionString = "";
using (var con = new SqlConnection(connectionString))
{
var sql = "Select Terminal from Form_IntranetSharpTransit_DispatchInfo where ([Dispatch] = #Dispatch)";
using (var cmd = new SqlCommand(sql, con))
{
cmd.Parameters.AddWithValue("#Dispatch", getDispatchNumber());
con.Open();
result = (string)cmd.ExecuteScalar();
}
}
return result;
}
protected string getDriverName()
{
string result;
string connectionString = "";
using (var con = new SqlConnection(connectionString))
{
var sql = "Select Driver from Form_IntranetSharpTransit_DispatchInfo WHERE ([DispatchInfoID] = #DispatchInfoId)";
using (var cmd = new SqlCommand(sql, con))
{
cmd.Parameters.AddWithValue("#DispatchInfoId", getDispatchInfoId());
con.Open();
result = (string)cmd.ExecuteScalar();
}
}
return result;
}
}
And here is my code behind.

All I want is to display the table with an edit button. When the edit button is clicked, I want the label in table to become an edit box (as my template shows). After the user has modified the edit box, they can then click the update button, committing the change to the database and refreshing the table to show the changed values.
This seems extremely simple but I have been struggling with it for about 3 months now.
Please help.

Here's a minimal, yet working, example of what you are trying to achieve.
Though I must admit, the Microsoft Documentation came in pretty handy for this snippet.

How to update the page without reload using update panel ?AP.NET C#

I have a gridview which contains an edit and a delete command.
I would like that when I click on edit, update the value, and click on delete that the value is deleted from database and the page is not reloaded.
Now, I use update panel and script manager but the page is reloaded again, the Update panel is not working. And my other problem is when I put <form runat="server"></form> form tag before gridview then it's working fine, the gridview shows, but when I remove this tag then an error appears:
object reference not set instance object.
My aspx code is :

Your code is not well formatted, the UpdatePanel is outside the form, and gridview also is outside the form. It must be like that...
<form runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:GridView>
...
</asp:GridView>
</ContentTemplate>
</asp:UpdatePanel>
</form>

First things first:
<%-- Your code (fragment) --%>
<EditItemTemplate>
<asp:TextBox ID="txtDatabaseName" runat="server" Height="22px"
Text='<%# Eval("Database_Name") %>' Width="192px"></asp:TextBox>
</EditItemTemplate>
Eval is ReadOnly (OneWay) binding. It should be
<asp:TextBox ID="txtDatabaseName" runat="server" Height="22px"
Text='<%# Bind("Database_Name") %>' Width="192px"></asp:TextBox>
Next. I would recommend you to use <asp:SqlDataSource... which takes all dirty work to itself (select, update, and delete). You can sent your UserID parameter to the parameters like this:
<asp:Literal ID="userId" runat="server" Visible="false"></asp:Literal>
...
<asp:SqlDataSource ID="sqlDS"...
<SelectParameters>
<asp:ControlParameter ControlID="userId" PropertyName="Text" Name="ID" Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
...
In GridView add DataSourseID="sqlDS"
In Page_load set value userId.Text=ID.ToString();
Try this way.

how to populate a dropdownlist based on selection of another dropdownlist in a gridview

I have a gridview with it's own sqlDataSource. In the footer row, I have an Insert field to create a new row. However, that footer row is quite complex and I'm trying to figure out how to make it work.
What I would like to see happen, is that a user Selects the OTypeName ddl. Based on that selection, the OSpecies ddl is enabled and populates values based on the OTypeName ddl. The same can be said in relation to OSpecies and OVariety.
The user then inputs their own information into OAge, OYields, OPlantDate, and OPlantFrom.
The rest of the fields in the footer row are labels that will be populated based on the final OVariety selection.
The Insert button then adds all these columns to the gridview.
I only need help with populating one ddl based on the ddl selection of another and how to populate a label based on a ddl selection.

Example of Orchard Gridview

Just to give you an idea, you should handle this on your code-behind (I noticed that the AutoPostBack property is set to true)..
Let's say on ddl1 value change event or similar:
var ddl1Value = ddl1.SelectedValue;
ddl2.ItemSource = ddl2DS.Where(item => item.Field1 = ddl1Value);
ddl3.ItemSource = ddl3DS.Where(item => item.Field1 = ddl1Value);
Basically you will just filter the item source of the other drop down lists as the value of your first drop down changes.
If you want you can also use javascript to perform this exact same concept to avoid postbacks.

Automatically create labels based on the number of database entry's c# asp.net mssql

Is there a way to generate labels based on how many user entry's there are in a database and print the database information to the labels on page load.
I have attempted to do this by binding the data but i found i can only do this in a grid format and i don't want a grid.
What i am trying to create overall is a survey in which the questions are stored in the database and displayed on the labels. I want someone to be able to add a question to the database and a label to be automatically generated for it displaying the question.
I am able to get my desired effect but i have added labels and written the questions on them manually. If anyone can please help or advise if it can be done it would be much appreciated. Thank you in advanced.

You are on the right track to use data binding. If you want to have more control over the HTML that is generated, you can use a Repeater control. This way, you can specify templates for the items you want to display.
The following sample shows a Repeater. In the ItemTemplate, a HiddenField stores the question id and a Label shows the text. When the page is requested, the items are retrieved from a database (the sample uses test data) and bound to the Repeater. I've also added a dropdown in the ItemTemplate so that the user can select an answer. Upon clicking the Save button, the values are retrieved from the controls in the items of the Repeater.
ASPX
<asp:Repeater ID="rpt" runat="server">
<ItemTemplate>
<p>
<asp:HiddenField ID="hiddenId" runat="server" Value='<%# Eval("Id") %>' />
<asp:Label ID="lblQuestion" runat="server" Text='<%# Eval("Text") %>' />
<asp:DropDownList ID="ddlAnswer" runat="server">
<asp:ListItem Text="1" />
<asp:ListItem Text="2" />
<asp:ListItem Text="3" />
</asp:DropDownList>
</p>
</ItemTemplate>
</asp:Repeater>
<asp:Button ID="btnSave" runat="server" Text="Save" OnClick="btnSave_Click" />
Code Behind
public partial class Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
var questions = GetQuestions();
rpt.DataSource = questions;
rpt.DataBind();
}
}
private IEnumerable<Question> GetQuestions()
{
// Load questions from database
// Setting up some sample data for this sample
var lst = new List<Question>();
return Enumerable.Range(1, 5).Select(x => new Question() { Id = x, Text = "Question " + x.ToString() });
}
protected void btnSave_Click(object sender, EventArgs e)
{
var dictAnswers = GetValuesFromRepeater();
// Save answers to database
}
private IDictionary<int, int> GetValuesFromRepeater()
{
var dict = new Dictionary<int, int>();
foreach (RepeaterItem item in rpt.Items)
{
if (item.ItemType == ListItemType.Item || item.ItemType == ListItemType.AlternatingItem)
{
var id = int.Parse(((HiddenField)item.FindControl("hiddenId")).Value);
var answer = int.Parse(((DropDownList)item.FindControl("ddlAnswer")).Text);
dict.Add(id, answer);
}
}
return dict;
}
}
public class Question
{
public int Id { get; set; }
public string Text { get; set; }
}
Please note that when retrieving the values from the repeater, the controls have to be found by their id using the FindControl method.

SqlConnection con = new SqlConnection(connectionstring);
SqlCommand cmd = new SqlCommand ("select fields from database", con);
con.Open();
SqlDataAdapter sda = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
sda.Fill(ds);
foreach (DataRow dr in DataSet.Tables[0].Rows){
Label lbl = new Label();
lbl.Text = dr["column"].ToString() + ":";
TextBox txt = new TextBox();
txt.ID = "txt" + dr["id"].ToString();
}
You have to push it into !IsPostBack
On saving you have to take all IDs into some array or list, and use foreach array:
foreach (int id in id_array){
command.Parameters.AddWithValue("#"+param+id.ToString(), (TextBox)(Page.FindControlById("txt"+id.ToString())).Text);
}
But you also have to think about your sql_query (in code-behind or stored procedure, make it responsive, depending on params number).
Hope it helps

Visual Studio 12 - Gridview inserting footer row on submit

I have a gridview that I need a footer row inserted with the data from a textbox when the user hits submit. I have tried over and over and I can not get past the following error:

It looks like your SqlDataSource2 is causing the error. Please double check that both Name and Email are of DB type string in your DB.
In your ASPX SqlDataSource2 make the following changes:
<InsertParameters>
<asp:QueryStringParameter Name="Name" QueryStringField="Name" DbType=String />
<asp:QueryStringParameter Name="Email" QueryStringField="Email" DbType=String />
</InsertParameters>
In your C# Code-Behind, change to this:
SqlDataSource2.InsertParameters[0].DefaultValue = txtAddName.Text;
