I want to basically check if user has entered any control characters
like 1-32 or 127 ASCII value (Ex: ALT + 127) in the edit box. And discard the same.
FYI this edit box should allow any other non english characters like French, German, Chinese, Japanese etc

Hello
I am trying to DoubleClick a row in a datagridview and open new form
and have textboxes populated from selectedrow.

This opens new form, not sure if its catching data

private void dataGridView1_CellContentDoubleClick(object sender, DataGridViewCellEventArgs e)
{
MasterForm.ActivateTab(2);
string strTemp = "";
strTemp = dataGridView1[dataGridView1.CurrentCell.RowIndex, 0].Value.ToString();

}

How do I bind it on next page/form to populate textboxes for selected columns?

Many thanks in advance Big Grin | :-D

Hi,
A solution is to store the full row in the session object :
Session["selectrow"] = myDataSource.myTable.Rows[dataGridView1.CurrentCell.RowIndex];

Then in the load of the second page your read values from the session object :
mytextBox.Text = ((DataRow) Session["selectedrow"])["mycolumn"].ToString();

What do you mean by "from Datagridview to Datagridview" ?? It's not very clear for me.

Take a look at the SelectedItems property.

Hello All,

I am developing a shopping cart and both registered users and anonymous users can shop. The problem iam facing is with anonymous user how to create a visitorId so that i can link them to shopping cart. Visitor ID should be unique ie for every user, do i use session for this. Any suggestions guys.

Best Regards, Shilpa. Smile | :)

Hi,
You can use the SessionID property of the session. it's unique.
You can also create your own ID (a guid for example) and store it in the session object :
Guid VisitorID = Guid.NewGuid();
Session["VisitorId"] = VisitorID;

Why Buttons look different and have different visual effect? [modified]

Khoramdin1-Mar-07 15:50

Hello everyone,

I have realised that there are Visual differences between the Button images. Some of them are square and look like the old fashion Windows Application and some like Windows XP.

It seems whenever the code is written in Visual Studio 7 once they are opened in Visual Studio 8 even after the converstion is successful, the button image looks like the old windows 3.1.

Here is an example for the square old windows style:
http://www.codeproject.com/listctrl/listview.asp[^]

Here is an example to show the rounded Button Windows XP look alike is this example:
http://csharp.simpleserial.com/[^]

What I find strange is that if I start a new project in Visual Studio 8 it creates Button shown in example Two but if I build on a project which was initially created in Visual Studio 7 then all the buttons look squared and old style including the Buttons which were added to the application in Visual Studio 8.

I have checked the Button Propeties and they are identical!!! Can someone tell me how we can change the Button Shown in example one into the one shown in example two?

Thank you so much for your help and have a great day.

Hi,

the esthetic improvement in some controls is called "VisualStyles"; you must enable
it explicitly to get it, and it needs/uses a more recent version of one of the
system's dll files.

There are different ways to enable VisualStyles, one of them is calling
Application.EnableVisualStyles() before Application.Run().
But is exists only since .NET 2.0

For more info please search CodeProject for VisualStyles, or read the documentation.

Hi All:

I am trying to draw small points ontop of an origin background. I am trying to plot points in a 4 coordinate background. So I want the background to be stationary and the points to change given the incoming values. How can I do this? Right now my background is redrawing everytime I draw the small square so it looks awful! Frown | :(

Please help!

You need to turn on double buffering, probably. Sorry, you need to google for the code, don't know it off hand.

You also need to post your code, so we can see how you're going about it.

Databinding problem

ejbing1-Mar-07 12:37

1-Mar-07 12:37

I have a slight bug in one of my programs. It is a program that involves databinding with ADO.NET 2.0. My main form is bound to one of the tables. I have another form and a combo-boxon my main form that is bound to the other table (there are only two) in the database. When I run the application, I find that the individual forms work correctly, but the combo-box does not update if I add a new field in the other form unless I restart the application after closing it. I need a way to refresh that combo-box! Please help!

I believe the correct form is to do another fill in your main form after returning.

dataAdapter.Fill(dataSet, [table]);

Hope this helps
