TextBox Value Is Not Updating In VS 2008?
Oct 14, 2010
I'm using following DropDownList event to select an employee from MS SQL Server 2005 and showing the employee's information on TextBox.
protected void employeeDropDownList_SelectedIndexChanged(object sender,
EventArgs e)
{
EmployeeDAL employeeDAL = new EmployeeDAL();
DataTable dataTable = employeeDAL.GetEmployeeData();
for (int i = 1; i <= dataTable.Rows.Count; i++)......
But the problem is... values of the TextBoxes are not changing. I mean TextBoxes are keeping previous values those were assigned in employeeDropDownList_SelectedIndexChanged event. But why?

why this update is failing? The table is connected to OK and there are appropriate values in the parameters to the subroutine, and yet the record in the table remains unchanged. I am using exactly the same code (with different parameters, obviously) to update another table and this continues to work fine.
Public Shared Sub SaveMathsSettingOptions(ByVal ID As Integer, ByVal Auto As String, ByVal Repeats As Integer, ByVal Weekly As String, ByVal ClassSheets As Integer, ByVal HomeSheets As Integer)
Dim con As New MySqlConnection(_connectionString)
Dim ret As String
Dim sql As String
sql = "UPDATE centres SET maths_auto = @maths_auto, maths_auto_reps = @maths_auto_reps, maths_weekly = @maths_weekly, maths_class_sheets = @maths_class_sheets, maths_home_sheets = @maths_home_sheets WHERE centreID = @centreID"
Dim cmd As New MySqlCommand(sql, con)
cmd.Parameters.AddWithValue("@maths_auto", Auto)
cmd.Parameters.AddWithValue("@maths_auto_reps", Repeats)
cmd.Parameters.AddWithValue("@maths_weekly", Weekly)
cmd.Parameters.AddWithValue("@maths_class_sheets", ClassSheets)
cmd.Parameters.AddWithValue("@maths_home_sheets", HomeSheets)
cmd.Parameters.AddWithValue("@centreID", ID)
Try
con.Open()
Catch myerror As MySqlException
'MessageBox.Show("Error Connecting to Database: " & myerror.Message)
ret = myerror.Message
con.Close()
Finally
con.Dispose()
End Try
End Sub

I'm facing the following issue:
I have a gridview that allows updating. I only want to show the relevant fields to the user. As a result I hide the ID field of the records. But I need this value as a parameter for my update command. Apparently the value is always passed as 0 when the field is set invisible. When the field is set visible, the right value is passed.
I know it is possible to refer to a selected row and its controls, to get their values, even for invisible fields. This is what I want to do when the row is updating, in order to get the ID value of the label control which holds the ID value. How do I refer to the row that is updating? I experienced that the row is not considered 'selected', so the SelectedRow property of the gridview does not do the trick.

Which is the correct event to handle Updating of a row in my gridview. The gridview is bound to an objectdatasource. I added a tamplate field like this to handle editing a row:
Code:
<asp:TemplateField ShowHeader="false">
<ItemTemplate>
<asp:LinkButton ID="lbEdit" runat="server" CausesValidation="False" CommandName="Edit" Text="Edit"> </asp:LinkButton>
</ItemTemplate>
[Code] ....
No I need to handle the Update Button click.I need to set the ObjectDatasources Update params and call the update method. I'm not sure which is the correct event to do this. IS it gridview_RowUpdating??

I have an excel sheet with 2 tabs and has data in those 2 sheets(sheet1, sheet2) which correspond to different tables in the same database. This excel sheet gets updated daily, I am wiriting a console app( which will later be a batch build). I have to insert the data from the excel sheet to corresponding tables (table1, table2,table3) in database when i run it and and also if the table has the same data already present it should ignore and if there are any modifications done the data it should update the table. I know we can do this using ado.net or LINQ, I am a little new to database based programming .

I've been trying to resolve this issue for like 10 hours but with no luck. I am trying to load data from a db to text boxes and allow the user to enter his/her modifications and click a button to update the db with the entered value in the textboxes. The problem is the entered data are not sent to the db but the data that are loaded when the page is loaded is what it goes to the db. I also tried vb codes and javascript to change the data of the textbox but that did not work.
here is my code:

I am trying to update the table records by intering a new values in a textbox
and am facing problems in the code of dataset
how could I perform that
[code]....
You should post any code that you are having problems with in the thread (because apparently some people can't open the files attached).
Anyways, you need a TextBox on the page. Then you need to access the Text in the TextBox (using the TextBox.Text property). Once you've got that you should use it to update your database.
The best way to supply this value (that has been provided by the end user) is to use the SqlCommand.Parameters property (if you're using the SqlCommand object).
This topic is covered nicely in:

I'm trying to set up an update button to update the infomation in my database using a stored procedure and method with the following code but when I click the button it doesn't add the updated text so i debugged the code and saw that the line "bool success = DataAccess.UpdateAboutUs(ID.Text, txtHeader.Text, txtHeader2.Text, txtDescription.Text);" was still taking the text that was loaded into the textboxes.

I retrieve a record on my database through Page_Load event here's the content of my Code:
hMenuID.Value = Request.QueryString["id"];
//Display information of links on the entries
cnDBConnection.ConnectionString = clsFunction.strConnection;
cnDBConnection.Open();
cmModule.Connection = cnDBConnection;
cmModule.CommandText = "SELECT * FROM modules WHERE id=" + clsFunction.ReplaceString(hMenuID.Value.ToString());
rdModule = cmModule.ExecuteReader();
if (rdModule.HasRows == true)
{
rdModule.Read();
txtModuleLabel.Text = rdModule["name"].ToString();
txtModuleLink.Text = rdModule["link"].ToString();
cboParentID.SelectedValue = rdModule["menuid"].ToString();
}
cmModule.Connection.Close();
rdModule.Close();
cnDBConnection.Close();
So, the data appears on my textboxes and a combo box. I tried to modify the content of my textbox and click on the Update button. Unfortunately, there's no modification that happen. Here's my code in the Update button
Code:
if (Page.IsPostBack)
{
if (Page.IsValid)
{
cnDBConnection.ConnectionString = clsFunction.strConnection;
cnDBConnection.Open();
cmModule.Connection = cnDBConnection;
cmModule.CommandText = "UPDATE modules SET name='" + clsFunction.ReplaceString(txtModuleLabel.Text.Trim()) + "', link='" +
clsFunction.ReplaceString(txtModuleLink.Text.Trim()) + "', menuid=" + cboParentID.SelectedValue +
" WHERE id=" + hMenuID.Value;
cmModule.ExecuteNonQuery();
cmModule.Connection.Close();
cnDBConnection.Close();
}
}

I have a server side procedure that opens a tcp socket to a server then recieves chunks of data from the server. The server side code does this in a loop, collects the data as a string, then finally displays the data in a textbox. It all works fine.
My problem is, as the chunks of bytes are returned, I need to update a client textbox or lable showing bytes received on each iteration of the loop. I've tried injecting client side java and I've tried using such things as the updatepanel and/or updateprogress controls. I haven't gotten anything to work. It always seems to only update the client on the last iteration. i.e. in a server side procedure/loop, update a client side textbox/label. Or maybe tell me what I am doing wrong? This is some of the code I am using now without using an updatepanel or updateprogess:

I have an updatable Gridview control that I cannot seem to URL encode a textbox in one of the columns. I cannot encode some of the other controls in the row, so the solution from the msdn site doesn't work in my case. I only want to encode the single textbox. However, with the code I have, I don't get any errors, and the database is updated, but the column that is edited becomes empty in the database. Here is what I have in the gridview rowupdating:

I have a method that takes a LINQtoSQL object and a field name and will tell me the length of that field based on the attributes of that field within the class object. I want to use this method to set the maxlength of any bound textboxes in a gridview. I can loop through all textboxes, and if the textbox created from a bound field then i can get at the fieldname ok, however if it's created from a template i can't find any way of getting to the field name the textbox is bound to (since a template isn't bound to anything). What i'm after is a way of getting the field name the Text property of a TextBox is bound to in (ideally) any case, not just the case where it was created from a bound field.
