As a example the DataGridView allow you to edit a colums or add a column, select the datasource...
Send me a how to do or a web address would be fine.

Thank's Shajeel,
But I don't want to use all this ActiveX elements from the COM components.
Can we find a better simpler code for .Net 2.0?

i wanna clone a mdi child form when user click the "clone" button.
How can i do ?
|
|
|

There is no simple function in the framework to do this. Thus you will have to make it yourself. If you give some further informations on what is contained in your form whe might be able to give you some advice on how to start.
Generally speaking you will have to create a new instance of the form and copy everything what is not generated in the constructor/InitializeComponent from the old to the new form.

I have an application that has 3 panels one on top of the other.
Each panel contains several control.
I also have a toolbar that I am using to navigate between the panels using the SendToBack() and BringToFront() methods and with the Hide() and Show() methods.
For some reason when I want to show the the 3rd panel, I get the controls of the first panel together with the 3rd panel.
This problem doesn't happen when I display the 2nd panel or the first panel.
Help will be appreciated.
Topaz
P.S.
this is the code:
switch(e.Button.Text)
{
case "Option 1":
this.panelOption2.SendToBack();
this.panelOption3.SendToBack();
this.panelOption1.BringToFront();
this.panelOption1.Show();
this.panelOption2.Hide();
this.panelOption3.Hide();
break;
case "Option 2":
this.panelOption1.SendToBack();
this.panelOption3.SendToBack();
this.panelOption2.BringToFront();
this.panelOption2.Show();
this.panelOption3.Hide();
break;
case "Option 3":
this.panelOption2.Show();
this.panelOption2.SendToBack();
this.panelOption1.SendToBack();
this.panelOption3.BringToFront();
this.panelOption3.Show();
break;
default:
break;
}

In Windows Form Designer generated code
you find the "panelOption3.Controls.Add(someControl);" etc.
Have you checked to see that your buttons in panelOption1 isn't also added to panelOption3?
Sounds like it since they show for both panels.

Panel1 is added to the From
panel 2 is added to panel 1
panel 3 is added to panel 2
I checked and all controls that should be on panel1 are where they should be.
The same is true for controls of Panel2 & Panel3

Given this info the solution I posted will surely not work. I thought all panels were placed on the same container control. Is there any reason why you are placing within each other?
|

Robert,
You were right, I was wrong to put the panels one on top of each other instead of puting them on the form itself.
Thanks a lot for your time.
Thanks also to theRealCondor and Larantz

You should recheck what Larantz suggested but you can also make your life a bit easier:
this.panelsOption1.Visible = e.Button.Text == "Option 1";
this.panelsOption2.Visible = e.Button.Text == "Option 2";
this.panelsOption3.Visible = e.Button.Text == "Option 3";

It's hard to explain...but I get a bad feeling about what you are trying to do here. If you want to have an area that dynamically changes, I'd recommend a somewhat different approach that more cleanly fits into the windows paradygm.
What I would do is to have a single panel. Each set of controls would be removed from the form and created as individual UserControl objects. When the need comes to show the different view, clear the controls in the panel and create/add the required user controls. You can modify the constructor of the controls passing whatever data is needed to initialize the view.
If you find that the controls don't sit just right in the panel you can add some logic such as this:
panel.Controls.Add( functionControl );
functionControl.Docking = Docking.Full;
form1.Invalidate();
So you add the control, dock it so it fills the panel, then invalidate the form to get the new control visible.

I have found a ListView control on the web that has been extended to include additional functionality. Unfortunately it now has a problem. When you click on a ListViewItem it does not select it. i.e. it does not highlight the item like it would normally in a normal ListView control.
Could you tell me what events and methods I should change to make it select an item when the user clicks on one item?
Much appreciated.

Can you provide a link to the ListView control as they can vary greatly?

You can find the data in the rows and columns i.e like this:
string pwd = dset2.Rows[i].ItemArray[i].ToString();
Since you're asking for password for one specific user, you can do this:
string pwd = dset2.Rows[0]["Password"].ToString();
string pwd = dset2.Rows[0].ItemArray[0].ToString();
