Use the DataGridView's CellEnter event, and then use the CurrentCell property:
private void dataGridView1_CellEnter(object sender, DataGridViewCellEventArgs e)
{
label4.Text = dataGridView1.CurrentCell.Value != null ? dataGridView1.CurrentCell.Value.ToString() : String.Empty;
}
Notice that I'm also checking here if the cell value is null, and setting the textbox text to String.Empty if it is, otherwise you get a nasty Null Reference Exception when trying to call ToString() a non-existent value.

Hi,
I've seen some programs use wide images which have like 3 images inside and on run-time only a third on the image is shown in a picture-box and on mouse-over a different third of the image is shown and on-click a different third of the image is shown. does anyone know how to do that or there any built class for such things?
Thanks

Hi,
there is about 100 ways how you can do that  . However there is no class that would support that in .NET namespace directly. You have to write your own or maybe use somebody's else custom class. Override the OnPaint method of control class and render the part of Image you need according to mouse state (whatever condition).
hope that helps

is there a way that you can manually sort gridview columns
basically i want the columns to display in alphabetical order but only one column seems to display a-z at a time
i want a user to be able to click on sort a-z one column then sort a-z in another so both columns and together sorted a-z
hope this makes sense !

Jamie - yes multiple-column sorting is possible, but requires a little bit of work on your part. Here's an article to get you started: http://windowsclient.net/blogs/faqs/archive/2006/07/10/how-do-i-sort-on-multiple-columns.aspx[^]
If you're using .Net 3.5 you could also use LINQ.

hi
i am having two forms
form1 is having two functions and a bool variable
code is ::::
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
public bool s = true;
Form2 f2 = new Form2();
private void Form1_Load(object sender, EventArgs e)
{
f2.MdiParent = this;
f2.Show();
}
public void a()
{
MessageBox.Show("u r in a ");
}
public void b()
{
MessageBox.Show("u r in b ");
}
}
the code for form 2 is
:::::::
public partial class Form2 : Form
{
Form1 ff;
public Form2()
{
InitializeComponent();
ff = (Form1)this.MdiParent;
}
private void button1_Click(object sender, EventArgs e)
{
ff.a();
ff.b();
if (ff.s == true)
{
MessageBox.Show("yes");
}
}
}
error is coming at ff.a().. ff.b()...ff.s as object reference not set to an instance of the object ....

The problem is as the exception said. In other words, ff is null.

Think about the sequence that your statements are actually called in. You assign ff to be the MdiParent BEFORE you tell the form what its MdiParent is. Therefore ff is null because MdiParent is null at the time that ff is assigned.
The solution is to assign ff AFTER MdiParent is assigned. OR Don't use ff at all but to reference the MdiParent directly when it is needed.
You might also want to give things a sensible name. Form1, Form2, ff, a(), b() and so on are very poor names. They mean nothing to anybody.

Have you read the documentation[^]? It seems to have a fairly comprehensive example.

You add the project output of both the service and windows application to the installer. All three projects will, naturally, sit in one solution.

I'm trying to develop an application for a player's statistics per game. Here's the XML:
<GameStat>
<PlayerID>21</PlayerID>
<TeamID>8</TeamID>
<GameID>
<int>1</int>
<int>2</int>
<int>3</int>
<int>4</int>
</GameID>
<Score>
<int>18</int>
<int>25</int>
<int>15</int>
<int>31</int>
</Score>
</GameStat>
These data will be stored in an SQL Server Database. I have two tables, namely tblGame & tblGameInfo. When inserted in the database, the data will look like this: (pls don't mind the --)
tblGame
------------------------------------------
GameStatID----------PlayerID----------TeamID
1------------------------21----------------8
------------------------------------------
tblGameInfo
------------------------------------------
GameID----------Score
1--------------------18
2--------------------25
3--------------------15
4--------------------31
------------------------------------------
Can anybody please help me with this? Thanks

I think googling for SqlDataAdaptor, DataSet and DataTable will get you on your merry way
DataSet is basicly an in-memory kind-of database and DataTable are your tables. You can load your xml file in those.
If that's done, you can do whatever you want with it.
You can use it as a datasource, port it (trough the SqlDataAdaptor) to your database etc...
Hope that helps

I assume your are creating form3 in form2 as follow
<br />
<br />
form3 frm = new form3();<br />
<br />
then add
<br />
<br />
frm.mdiparent = this.mdiparent;<br />
<br />
Simple isn't it ?

Hi,
Just set the gridview's Enabled property to "False", i.e.
<br />
GridView.Enabled=False<br />

this doesnt stop someone right clicking on the text and copying it, this is what i need for them not to be able to right click and copy the text
any ideas?
|
|
|
|
|
<asp:gridview visible="false">
Im afraid thats about your only choice. Im afraid that putting something on the internet makes it highlightable, right-click-able, view-sourceable or printable. There is no sure fire way of stopping any of these methods of copying the page short of making it invisible or not putting it on the internet to start with.

You can do it with some javascript, BUT that will work only against totally non-tech users. Anyone who know how to disable javascript or view page source in browser will be able to steal whatever you send to client.
