C# GridView get textbox input

I have a problem that is most likely easy but I'm missing something small.
I have looked at numerous entries on Stack Overflow with the same question but I must be doing something wrong.
I am trying to get the value of a textbox in a GridView after typing into it. I want to take that value and update a SQL field.
Here is my GridView:
<asp:GridView ID="ASPxGridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="SALESID" HeaderStyle-HorizontalAlign="CENTER" HorizontalAlign="CENTER" CellPadding="4" ForeColor="#333333" GridLines="Both" AllowSorting="true" AllowPaging="true" PageSize="100" OnRowDataBound="ASPxGridView1_RowDataBound" OnSorting="ASPxGridView1_Sorting" OnRowUpdating="ASPxGridView1_RowUpdating">

Here is my gridview _RowUpdating method:
protected void ASPxGridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
Debug.WriteLine("row updating");
int index = Convert.ToInt32(e.RowIndex);
Debug.WriteLine("Index: " + index);
GridViewRow selectedRow = ASPxGridView1.Rows[index];
TableCell itemIDSelected = selectedRow.Cells[1];
TableCell rowPRD = selectedRow.Cells[11];
TableCell rowShipToday = selectedRow.Cells[12];
TableCell rowNotes = selectedRow.Cells[13];
string itemIdSelectedText = itemIDSelected.Text;
string rowPRDSelected = rowPRD.Text;
string rowShipTodaySelected = rowShipToday.Text;
string test = ((TextBox)selectedRow.FindControl("NOTES")).Text;
string test1 = ((TextBox)ASPxGridView1.Rows[index].FindControl("NOTES")).Text;
TextBox test2 = ASPxGridView1.Rows[index].FindControl("NOTES") as TextBox;
string test2text = test2.Text;
//string rowNotesSelected = rowNotes.Text;
//Debug.WriteLine(itemIdSelectedText);
//Debug.WriteLine(itemIdSelectedText);
//Debug.WriteLine(rowPRDSelected);
//Debug.WriteLine(rowShipTodaySelected);
Debug.WriteLine(test1);
Debug.WriteLine(test);
Debug.WriteLine(test2text);
//Debug.WriteLine(selectedRow.Cells[0].Text);
//Debug.WriteLine(selectedRow.Cells[1].Text);
//Debug.WriteLine(selectedRow.Cells[2].Text);
//Debug.WriteLine(selectedRow.Cells[3].Text);
//Debug.WriteLine(selectedRow.Cells[4].Text);
//Debug.WriteLine(selectedRow.Cells[5].Text);
//Debug.WriteLine(selectedRow.Cells[6].Text);
//Debug.WriteLine(selectedRow.Cells[7].Text);
//Debug.WriteLine(selectedRow.Cells[8].Text);
//Debug.WriteLine(selectedRow.Cells[9].Text);
//Debug.WriteLine(selectedRow.Cells[10].Text);
Debug.WriteLine(selectedRow.Cells[11].Text);
//Debug.WriteLine(selectedRow.Cells[12].Text);
//Debug.WriteLine(selectedRow.Cells[13].Text);
Debug.WriteLine("-----------");
//Debug.WriteLine(rowShipTodaySelected);
//Debug.WriteLine(rowNotesSelected);
}
When I run this and I type something in, the debug writeline's show.
I know i'm on the correct line because the index is correct per the line I am clicking the Update button on.
Sample debug output from above looks like this:
row updating
Index: 5
D31948P01
PRD-00030521
PRD-00030521
I cannot seem to get the value of the NOTES TextBox field.
As you can see with my testing I've tried using a FindControl and I've tried having it as a TextBox and also trying to get it directly to a string.
I've set breakpoints and each time I do it the test variable is null.
I'm missing something and I do not know what.
To summarize:
On non-text fields I can pull the data from the field.
On TextBox fields I cannot even using the FindControl method.
What I want to do:
Get the TextBox field value in the GridView so I can update the database.
StackOverflow links I've tried before asking this question:
c# Get value (text) of a bound textbox in a gridview
How to get value of TextBox of GridView in C#?
Manipulate textbox on gridview C#
Get TextBox value from GridView cell
ASP.net C# Gridview ButtonField onclick event
Thanks in advance. I've spent over 6 hours of attempting this without results. I don't understand it well enough yet. If there are any tutorials or videos explaining GridView's please let me know what they are so I can understand better.

The reason why RowUpdating method cannot find the text inside the textbox is most likely because of the postback. Clicking update button causes a post back to server. Before ASPxGridView1_RowUpdating is called, there is an a call to re-build the gridview ie.: ASPxGridView1.DataBind(). To avoid this, wrap the databind in an if (!Page.IsPostBack)
Below is a basic working example
<asp:GridView ID="ASPxGridView1"
runat="server"
AutoGenerateColumns="False"
OnRowUpdating="ASPxGridView1_RowUpdating">
<Columns>
<asp:TemplateField HeaderText="NOTES" >
<ItemTemplate>
<asp:TextBox ID="NOTES" runat="server" TextMode="MultiLine"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:ButtonField ButtonType="Button" HeaderText="" CommandName="Update" Text="Update" />
</Columns>
</asp:GridView>
Code behind:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
// This code will not be reached if you click update button.
var data = new string[] { "a", "b", "c" };
ASPxGridView1.DataSource = data;
ASPxGridView1.DataBind();
}
}
protected void ASPxGridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
int index = Convert.ToInt32(e.RowIndex);
GridViewRow selectedRow = ASPxGridView1.Rows[index];
TextBox txtNotes = (TextBox)selectedRow.FindControl("NOTES");
Debug.WriteLine(txtNotes.Text);
}

Save CheckBox Values in GridView to Database. ASP.NET

i am developing webform with gridview. I have a problem, the value of checkbox doesn't save in the table. I've tried everything nothing is working. After i press a button, value doesn't store.
And as you can see in my code, i don't use id for unidentified of each particular row, instead id i use foreach
protected void Button_Submit_Onclick(object sender, EventArgs e)
{
foreach (GridViewRow row in GridView2.Rows)
{
con.ConnectionString = ConfigurationManager.ConnectionStrings["TestDeductionsConnectionString2"].ToString();
bool private1 = (row.FindControl("CheckBox1") as CheckBox).Checked;
SqlCommand cmd = new SqlCommand("insert into DetailCosts(private) values(#private1)", con);
if (private1 == true)
{
cmd.Parameters.Add(new SqlParameter("#private1", SqlDbType.Bit));
cmd.Parameters["#private1"].Value = 1;
//cmd.Parameters.Add("#private1", SqlDbType.Bit).Value = 1;
}
else
{
cmd.Parameters.Add(new SqlParameter("#private1", SqlDbType.Bit));
cmd.Parameters["#private1"].Value = 0;
//cmd.Parameters.Add("#private1", SqlDbType.Bit).Value = 0;
}
con.Open();
cmd.ExecuteNonQuery();
con.Close();
}}
and there is a code with my Gridview:

At the back end code, i tried to retrieve the first column and specific rows but it throw me empty. the code below is how i retrieve.
int index = Convert.ToInt32(e.RowIndex);
string sapNo1 = GridView1.Rows[index].Cells[0].Text;
string partNo = GridView1.Rows[index].Cells[1].Text;
string partDesc = GridView1.Rows[index].Cells[3].Text;
I try to show all the value for sapNo1, it throw me blank but for partNo it will show the data in the gridview.
anyone has any idea about this?
I am really appreciate your help and comment!

As your first column is a linkbutton so retrieve that as it is then find the value.
string sapNo1 = GridView1.Rows[index].Cells[0].Text; // wrong code to retrieve data from linkbutton in a gridview
Modify this as :
LinkButton linkbtn =(LinkButton)GridView1.Rows[index].FindControl("LinkButton1");
string sapNo1 = linkbtn.Text;
or
string sapNo1 =(GridView1.Rows[index].FindControl("LinkButton1") as LinkButton).Text;

You can't get the controls properties present inside TemplateField like that, you need to find the control like this:-
LinkButton LinkButton1 = (LinkButton)GridView1.Rows[index].Cells[0]
.FindControl("LinkButton1");
After this you can simply fetch the properties of this control:-
string sapNo1 = LinkButton1.Text;

you can get the link button description by the below code
protected void Link_Button_Command(object sender, CommandEventArgs e)
{
try
{
LinkButton button = (LinkButton)sender;
string name = button.ToString();
}
catch (Exception ex)
{
lbl_message.Text = ex.Message;
}
}

Two gridview's selected indexchanged event does not work

C# code:
protected void gdv_SelectedIndexChanged(object sender, EventArgs e)
{
int indx = 0;
indx = gdv.SelectedIndex;
string salesorderno = "";
string sectionid = "";
string sectionname = "";
string outletid = "";
string outletname = "";
string salespersonname = "";
string orderdate = "";
string ordervalue = "";
string ordercheck = "";
for (int i = 0; i < 1; i++)
{
salesorderno = gdv.Rows[indx].Cells[1].Text.ToString();
sectionid = gdv.Rows[indx].Cells[2].Text.ToString();
sectionname = gdv.Rows[indx].Cells[3].Text.ToString();
outletid = gdv.Rows[indx].Cells[4].Text.ToString();
outletname = gdv.Rows[indx].Cells[5].Text.ToString();
salespersonname = gdv.Rows[indx].Cells[6].Text.ToString();
orderdate = gdv.Rows[indx].Cells[7].Text.ToString();
ordervalue = gdv.Rows[indx].Cells[8].Text.ToString();

}
lblOrderNo.Text = salesorderno;
lblSectionName.Text = sectionname;
lblOutletName.Text = outletname;
lblOrderDate.Text = orderdate;
LoadOrderReportDetailGrid(salesorderno);
}
protected void gdvOrderDetail_SelectedIndexChanged(object sender, EventArgs e)
{
}

test is sufficient to know the origin of the event.
Exemple :
private void dataGrid1_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
if(dataGrid1.SelectedItem!=null)
MessageBox.Show("aaaaaaaaaaa");
}
private void dataGrid2_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
if (dataGrid2.SelectedItem != null)
MessageBox.Show("BBBBBbbBBBB ");
}

Just open the event window for the gridviews then select one of them and on the event window double click on the "selected index changed" event. it will move you to the code section. if you are in true procedure than the event binding is true. if not you have to change the definition of your procedure.
Here is the simple process.
copy the codes inside the procedure and paste them to a safe place.
delete the procedures related the gridviews
check the event page for gridviews to ensure there is nothing in the "selected index changed" event.
double click the first gridviews "selected index changed" event. it will create a blank procedure. paste the related code here.
do the same for second.
and the other thing check the validation groups of the gridviews in the properties window. they should be different :)
NOT: forgive me that i cannot write the code directly. because i am not with my own computer. I hope it works.

Problems getting the control from GridViewRow

I have a gridview which is created on a button click. It has some checkboxes so the user can adjust the CRUD access rights for certain pages and then save all rows.
I have another button to save the rows where I loop through, getting the rowID and the access rights to save.
I am having a problem when saving, it can't find the control in the row and when it gets to ID= I get a object referenced exception. If I do the checkbox assignments first, I get the error on the C= part.
protected void btnSave_Click(object sender, EventArgs e)
{
foreach (GridViewRow r in gvRights.Rows)
{
if (r.RowType == DataControlRowType.DataRow)
{
int ID;
ID = Convert.ToUInt16(r.Cells[0].ToString());
bool C, R, U, D;
CheckBox chkC = r.FindControl("chkC") as CheckBox;
C = chkC.Checked;
CheckBox chkR = r.FindControl("chkR") as CheckBox;
R = chkR.Checked;
CheckBox chkU = r.FindControl("chkU") as CheckBox;
U = chkU.Checked;
CheckBox chkD = r.FindControl("chkD") as CheckBox;
D = chkD.Checked;
}
}
}

If you are adding your checkboxes programmatically you need to add them back in on each page load in the pageinit (before page_load). This way the controls are added on each postback and will get their values filled from the viewstate.
An easier way is to actually add the Checkboxes in your template field in the definition
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox runat="server" ID="chkC" />
</ItemTemplate>
<EditItemTemplate>
<asp:CheckBox runat="server" ID="chkC" />
</EditItemTemplate>
</asp:TemplateField>
