hi all,
i placed a tabcontrol on my form. but i want to open tabs with button clicks.
so what i want is to learn how to hide or erase tabpage headers ?
this image http://link.imgshare.us/82jVCE tells what i exactly want.
help me please.
thanks in advance,
bye.
ps: there may be other ways to do this but i dont know 
i want to place some buttons on the left hand side of the form and with each button click, i want to open something different (different pages) on the right hand side of that form.
i though that it can be done by tabcontrol...
i will appreciate your helps if you inform me whether there is other ways to do what i want or not?

You may want to consider ditching the tab control altogether and simply showing the appropriate UserControl in response to a button click.

if u have allready added the tabpages to tab control at design time
then u can remove the tabpages at the time of lloading form
tabControl1.TabPages.Clear();
then on button click event u can add tab pages by this way
TabPage tb1 = new TabPage("XYZ");
tabControl1.TabPages.Add(tb1);

Add/Remove the TabPages to/from the TabControl.TabPages collection as needed.
Or maybe put the controls in different Panels or GroupBoxes that are at the same position and only show the one needed.

I think you may try another way .
i suggest you try this :
place some Panel Controls . and put your Buttons on that
on Left Buttons . you can do click even like that:
Panel1.Visible = false;
Panel2.Visible = false;
Panel3.Visible = true;

"user" is a reserved word. Change the name of the table.

b { font-weight: normal; }

What does str_com expand to? Is user a reserved word in Access? Enclose the table name in square brakets like this [user]
What happens if the user types, as their user name, the following?
' OR 1=1; --
What is the code flow in that situation? What will be returned from the database if the user types that as a user name?
Your major problems are not syntax errors (because while you have syntax errors your application won't run and thus your data will be safe.) Your major problem is that your code is highly susceptable to a SQL Injection Attack (as I demonstrated above). You will likely wish to read about SQL Injection Attacks and how to prevent them.[^]

I have a Customize class that inherits a TreeView. This class has some extra properties, other than those from the TreeView. Is there a way to make this properties visible in the Properties box during design time?
|

|
|

Yes, you should insert:
[Browsable(true),
Description("..."),
Category("Design"),
DefaultValue("No Title")]
public String OwnTitle {
...
}

third argument is datamember where u have to specify table name
but i do not think it is possible to do databinding with dataview
u will still get the exception
so u can use datagrid.datasource = cusadd;

Hi,
please help me out to check the CheckedListbox only one item at click, rest of the items should be unchecked.
|
|
|
|
|
It's easy :
Use the event CheckedChanged then write this kind of code :
Go to each item, checked whether the item is the item you just selected.
If yes, then set the property "Checked" to true, otherwise false;
|
|
|
|
|
i found the solution ,
CheckedIndex is previously selected item index.
private void chkProperties_ItemCheck(object sender, ItemCheckEventArgs e)
{
chkProperties.ItemCheck-=new ItemCheckEventHandler(chkProperties_ItemCheck);
chkProperties.SetItemChecked(CheckedIndex,false);
chkProperties.ItemCheck+=new ItemCheckEventHandler(chkProperties_ItemCheck);
CheckedIndex=e.Index;
}

How many space you have - How many space you used = How many space is free
