Hello Friends,
I am facing a serious gridview problem, I am binding my gridview from code behind like(myGridView.DataSource=myDataSet; myGridView.DataBind()). But the problem is when i click the inbuilt "edit" button of the grid and the rows comes to edit mode, I cant able to get the cell values in any of the event like row_updating etc. For all the "rows(index)cells(index).Text" its displaying the blank text "". I am not able to figure out what the problem is. Please help me out friends....
I have tried all of these commands:
1). lblMessage.Text = CType(CType(e.CommandSource, LinkButton).NamingContainer, GridViewRow).Cells(4).Text
2). Dim m_ColumnText As String
m_ColumnText = GV1.Rows(GV1.EditIndex).Cells(4).Text
3). lblMessage.Text = Server.HtmlDecode(row.Cells(4).Text)
All are showing blank text, but i have values in my grid cells i can see it from my eyes.....i am very frustrated....plz...plz...help me out.
Thanks in advance.

Hi there,
What does your gridview look like? What is the column 4? If the cell 4 simply contains an input control like Textbox in Edit mode, the Text property returns empty.

Yes minhpc_bk, the cell 4 simply contains an input control like Textbox in Edit mode, and the Text property returns empty string ""....
Do you know the cause!!

Yes,  . In Edit mode, the cell does not contain text, but a text box so that the user can input the value, so the Text property of the cell should be empty. And if you want to access the value, you should cast the child control contained in the Controls collection of the cell 4 (.Controls[0]) to the TextBox control, then access the Text property of the textbox.

Urgent.reply needed immediately.
The session variable Session["strUserName"] becomes null and the 'session time out' message is being displayed.
function Session.get_item() evaluated and returned null.
This happens only when i have another browser window open before opening my web application.

I don't know right now. If I get some time over I might look into this.

b { font-weight: normal; }

i dont know right but i think this way dont be bad:
u can open global.asax.cs
and in htis function write this form:
protected void Session_Start(Object sender, EventArgs e)
{
Session["strUserName"]="aaa";
}
that means you can control that amount of session dont be null.

ViewState Concept is based on Hidden Field Concept
The main Purpose of ViewState is To maintain Persistant values for controls under postback implementation
Global.asax is the file that is compiled first when u complie ur application
It will have Session Events and applciation Events
U can have atmost one Global.asax for a project
Response.Redirect redirects from Ur Form to specific Site/Form
It causes roundtrip.U can pass query strings using this
Server.Transfer simply transfers the form to server.Here the transferred Url will not be visible to the user
Response.Output.Write writes the output in a more formatted form

g = Graphics.FromImage(bmp)
g.TranslateTransform(pb.Width / 2, pb.Height / 2)
g.DrawEllipse(New Pen(color.MediumTurquoise, 1), 0, 0, 2, 2)
cntnr = g.BeginContainer(rect1, rect2, GraphicsUnit.Pixel)
g.TranslateTransform(20, 20)
g.Clear(BackColor)
g.DrawRectangle(New Pen(Color.FromArgb(255, 255, 255)), 0, 0, 100, 100)
g.EndContainer(cntnr)
g.DrawLine(New Pen(Color.Blue, 1), 0, 0, 200, 200)
I'm confused why I lost all my scratches before the "g.BeginContainer",if I use the g.clear in the container?

Hi,
Does IIS (Win XP version) support multithreading?
If so,how do we manage multithreading in IIS?

I want to stay with GridView (unless another view can easily for sorting and display in rows), but I want to make some rows bold depending on the contents of a field. I have an extra text field returned with my query that is null of "Bold" and I want the null rows to show normal and the bold rows to show as bold. Can this be done? How?
Thanks

To change the format of the gridview row, you can create a handler for the RowDataBound[^] event of the GridView control. In the handler, you can format the background color of the row based on data using the BackColor or the CssClass property of the GridViewRow instance (e.Row).

VS2k5

.NET 2.0
In my ASP.NET 2.0 app I create and open an SQL connection in the page's constructor and call Dispose() in the destructor. The SQLConnection
object is a class member of the page. This page makes heavy use of the SQLConnection object so I felt opening and closing in the constructor/destructor respectively was good design. I know this doesn't take full advantage of connection pooling. Any design input would be very much appreciated.
Here's the destructor code:
/// Destructor
~Officer()
{
if( m_objConn != null )
m_objConn.Dispose(); // <-- Exception occurrs here.
}
/// End Destructor
When running this particular page through some testing I get the following exception in the destructor at the "m_objConn.Dispose();" line:
System.InvalidOperationException was unhandled
Message="Internal .Net Framework Data Provider error 1."
Source="System.Data"
StackTrace:
at System.Data.ProviderBase.DbConnectionInternal.PrePush(Object expectedOwner)
at System.Data.ProviderBase.DbConnectionPool.PutObject(DbConnectionInternal obj, Object owningObject)
at System.Data.ProviderBase.DbConnectionInternal.CloseConnection(DbConnection owningObject, DbConnectionFactory connectionFactory)
at System.Data.SqlClient.SqlConnection.Close()
at System.Data.SqlClient.SqlConnection.Dispose(Boolean disposing)
at System.ComponentModel.Component.Dispose()
at Officer.Finalize() in c:\sys\projects\AddOfficer.aspx.cs:line 46
1) Is this design good/bad?
1) Is this a bug?
2) Do I need a try/catch in a destructor? Is it good programming practice?
3) Why is this happening?
4) What is the meaning of life?
Any help is appreciated. TIA

Hi, I'm currently writing an application that has a collection of complaints (in an microsoft sql server database).
Now they want us to make it possible to upload files (mostly doc's and mails) and bind them to a complaint, so that later when another employee is browsing throught the complaints he can download/open files that belong to a certain complaint.
security is not an issue because it is an intranet application.
What we also thought of, was to store the files in the database (we're talking about a small app with few data) but I have no idea if that compromises performance or not.
As you can see we're quite new to all this, so any help is much appreciated, thx in advance.

You could, I suppose, handle the OnDayRender event and clear contents of cells you didn't want displayed. Something like this:
<%@ Page Language="C#" %>
<script runat="server">
void Page_Load(object o, EventArgs e)
{
}
void CustomDayRender(object o , DayRenderEventArgs e)
{
if (e.Day.Date >= System.DateTime.Today.AddDays(-3)
&& e.Day.Date <= System.DateTime.Today.AddDays(4))
{
e.Cell.BackColor = System.Drawing.Color.Honeydew;
}
else
{
e.Cell.Controls.Clear();
}
}
</script>
<html>
<head>
<title></title>
</head>
<body>
<form runat="server">
<asp:Calendar id="Calendar1" runat="server"
OnDayRender="CustomDayRender"
/>
</form>
</body>
</html>

HI,
I have read some papers and they tell that WSE 2.0 with WS-attachments does not encrypt the attachments ( they recommend using secure protocol like SSL to secure attachments). Now, WSE 3.0 replace WS-attachments with MTOM, I have found that MTOM is used for transmit large binary data, but I don't know whether we can encrypt it directly with WSE 3.0 or not.
If you have answer, plz tell me.
Thanks,
Hung
