Datareader does not support paging.
I Changed the WerkGridViewBij-method to:
<br />
public GridView WerkGridViewBij(GridView gv, Int32 paginaNummer, String DataSourceSelectCommand, MySqlParameter[] sqlParameters)<br />
{<br />
try<br />
{<br />
<br />
<br />
MySqlCommand cmd = BaseDatabaseData(DataSourceSelectCommand, sqlParameters);<br />
cmd.Connection.Open();<br />
<br />
if (gv.AllowPaging)
{<br />
DataSet dset = new DataSet("GeneralDataSet");<br />
DataTable tabel = new DataTable("GeneralTable");<br />
MySqlDataAdapter adapter = new MySqlDataAdapter(cmd);<br />
adapter.Fill(tabel);<br />
gv.DataSource = tabel;<br />
if (paginaNummer > gv.PageCount) paginaNummer = 0;<br />
<br />
if (gv.AllowPaging)<br />
gv.PageIndex = paginaNummer;<br />
gv.DataBind();<br />
}<br />
else<br />
{<br />
MySqlDataReader reader = cmd.ExecuteReader(CommandBehavior.CloseConnection);<br />
if (reader.HasRows)<br />
{<br />
gv.DataSource = reader;<br />
gv.DataBind();<br />
}<br />
reader.Close();<br />
}<br />
}<br />
catch (Exception err)<br />
{<br />
gv.ToolTip = err.Message;<br />
}<br />
finally<br />
{<br />
if (gv.Rows.Count.Equals(0) && gv.ToolTip.Equals(String.Empty))<br />
gv.ToolTip = "Geen data gevonden!";<br />
}<br />
return gv;<br />
}<br />
problem is solved

Hi,
I have a login control in my ASp.NET application. I use 'Users' table in SQL Server 2005 to authenticate the login. If the username & password are correct, I want to display the username in the loginview control. How can I do that?
|
|
|
|
|
put in a login view and put the login name in it .
if you want to display a message before the username use the format string in the properties window just don't remove the {0} at the end.

How to use flash and integrate it into ur website
www.2advanced.com
This website rocks
|
|
|
|
|
You can start by creating a flash movie.
For integrating into website, just use the object tag.
Point to note: Not all websites that use flash are "Wow". A badly designed flash interface can be irritating, difficult to maintain and may turn away users. Also its client-heavy.
Ajax should suffice unless you're creating a website for a las vegas condo.

Hi,
I have a textbox that accepts numbers. I need to extract just the numbers in the orders as what they were entered, irrespective of what other text is entered.
I have the following:
Dim r As New Regex("^\d+$")
Dim matches As MatchCollection = r.Matches(strNum)
Response.Write("matches.Count = " & matches.Count)
When I enter "123-456", matches.Count is 0, but when I add "123" then the count is 1. How do I modify the regular expression so that it extracts the numbers, if "123-456" or "123/456" is entered then the end result must be "123456".
Please can someone help?
Regards,
.NET Enthusiast

write your own code, like
Protected Function SelectNumbers(ByVal alphaText As String) As String<br />
Dim num As String = ""<br />
Dim c As Char<br />
For i As Short = 0 To alphaText.Length - 1<br />
c = alphaText.Chars(i)<br />
If Char.IsDigit(c) Then<br />
num &= c<br />
End If<br />
Next<br />
Return num<br />
End Function

It's not a datagrid, it's a table on the client side. You need to add rows to the client side table. A repeater is probably better for you to control how things are laid out for the javascript.

#1. You should check like ~
If dr IsNot Nothing Then If Not dr.IsClosed Then dr.Close()
#2. You should check whether dr is nothing or not before "dr.Read" too.

May be in this case you won't be getting dr object. Some exception happened before you issue ExecuteReader(), that will force to execute finally block. In finally block you are trying to close datareader that is not yet instantiated. To avoid this, make sure dr is not null before you try to close it.

You need to look for some good articles that explains SQL Injection attacks. Your code is too close to that. I feel better approach would be using parameterized queries or Stored Procedures.

Yes but what will happen if exception occurred before ExecuteReader() ? Then dr will not be instantiated
|
|
|
|

I agree, But i m post here as per the first post. if you want handle that kind of exception then we need to check Reader is null or not.
