The simplest version of this would just get the data you want to edit into a DataTable or DataSet object, bind the DataGrid to this DataTable, and let the user edit the data in the grid directly. When they're done, you can supply a button to save the information back to the database.
Getting the data is normally done using a DataAdapter to query the database and fill a DataTable or DataSet. When the user is done, call the Update method on the DataAdpater to write the changes back to the database.

try this one... its not for DataGrid.. this one works for MSFLEXGRID
Private Sub Form_Load()
Text1.Visible = False
End Sub
Private Sub MSFlexGrid1_Click()
If MSFlexGrid1.Col = 0 Then
Text1.Visible = True
With MSFlexGrid1
Text1.Left = .Left + .CellLeft
Text1.Height = .CellHeight
Text1.Width = .ColWidth(0)
Text1.Top = .Top + .CellTop
End With
Else
Text1.Visible = False
End If
End Sub
Private Sub Text1_Change()
With MSFlexGrid1
.TextMatrix(.Row, 0) = Text1.Text
End With
End Sub
The code is for editing the frst column of the grid...

This is normally done through the approparite use of container controls, like the TableLayoutPanel, SplitContainer, and various others. Combine these with appropriate use of the Anchor and Dock properties on your controls to get the scaling and sizing effects you want.
It just takes some playing about with the controls properties to get the effects you want. There really isn't a single good source for this information, and even fewer examples. The stuff I've seen just explains the control properties Anchor and Dock and that's about it.

www.activepdf.com has commercial server-based software.
www.primopdf.com has free desktop-based software (based on GhostScript).
There are a bunch of other products if you search on google.

Hi all,
I want to develop an level output meter like an 8 band equalizer. I saw some implementations to show a waveform, but this is not what I want. In the end the control should work like the winamp level meter. Has anybody an idea how to start?
Thanx!

make it more clear.. which platform are u looking??

I'will try to make it more clear. I developed a little tool for organizing and playing mp3 albums and files. To play the files I'm currently using the media player control. All that I want is to visualize the currently played mp3 in an 8-band level meter.
I'm using Visual Studio Express 2005.
Need more information?

It's called a "spectrum analyzer". This is actually going to be quite difficult to do. You can only use the data that is currently going through the audio mixer to feed the analyzer. Reading the MP3 file directly will do you no good because you can't tell where the current sound is in the file.
You can find an example of this here[^], but I'll warn you, it's not for the beginner.
You can also find more about them on Google, here[^] or even find libraries that can do this for you.

What do you want to do ? Showing them is fairly easy, if you embed IE in your app, it will do it. Creating them requires a third party library.

How r u making the listview control in the editing form?

A ListView isn't databindable, so that'll make this quite a bit more difficult. Why are you using ListView control? Why not a DataGridView?
It's possible to implement your own bindable version of the control, though. You can find an example here[^]. Warning! It's not something for beginners!

Hi Vuyiswamb
Try server side validation control, use date validation control, and use the "control to validate" property.
Hope it will help ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

Hi Vuyiswamb
Go through your toolbox there is a validation control
section, in that u get a date validation control, use that control...OR if you don't know how to use the control then just go through the MSDN and take help abt the validation control.
