It takes two of you to work this out ? Are you in a class ? If not, then you need probably to give up on windows for a while and learn enough basic programming to give you a background which would make you able to follow how these things work.
A checkbox has an event which is fired when the check state is changed. What you do when that happens is up to you, if it's setting the Enabled property, the Visible property, or something else. You asked to make a label visible, the answer you got was correct.

Sir,
I want to know something about the internal keyword and how it is different from the private keyword and one more questions please that is what is the difference between internal and protected internal.
Thanks

Internal is visible only to items inside the assembly. Protected internal is only visible to derived classes within the assembly.

Actually, 'protected internal' is visible to all derived classes and everywhere within the assembly. It is "protected OR internal", not "protected AND internal".

regards

A noetpad file is just plain text.
Your question makes no sense. How can we tell you how to store stuff that you've not defined ? You can make up any file format you like, and if it's more complex than plain text, no other app will open it, simple as that.

but how can i make that file format? by just giving a self defined extension? or there is some way to do that?

What are you asking ? Do you want your file to open when it's double clicked ? That's a registry entry ( easily found with google ). Do you just want to create the file ? ( Just use the System.IO namespace, and all the info you'd find with google ) Do you want to know the specifics of a file format for your app ? We really can't tell you.

This is bad UI. You can make it work, but select all should be a button, not one of the items in the list.

Not sure I agree with that. If you have a huge field of checkboxes, say to determine which fields to search on, one of the options could be All, which would select all of the checkboxes for you.
I've seen this done out in the wild, and it seems to make sense. Not saying there's not a better way, just saying I don't think it's a bad UI.
[edit]Ahh, it's a list box. Should have read that a little closer. I agree with Christian, use a button.[/edit]

You absolutely must have a list of checkbox items, and the first item must say 'select all' ? A button is a better choice . But, if you must make a god awful UI, just handle the event for an item to be checked, check if it's the 'check all' item, and if it is, check them all.

Ok...Can u tell me if i give a single CheckBox(say 'Selct All') outside this CheckBoxList then How i can select all ites in CheckBoxList on selction that CheckBox(Selct All).
Thanks for all your replies,
Vinay

If there's no CheckAll method on the checkboxlist, use foreach on the items collection to check them all.

Do you not know how for each works ?
foreach(CheckBoxListITem item in myBox.Items)
{
item.Checked = true;
}
I am sure that's not the type of the items, but that's how it looks.

you can you this too
<br />
for (int i = 0; i < this.checkedListBox1.Items.Count; i++)<br />
{<br />
this.checkedListBox1.SetItemChecked(i, true);<br />
}<br />

It doesn't matter what it is, having a check box that says 'select all' makes no sense, it should be a seperate control to the type of control that is being selected ( and probably a button )

My example doesn't say "Select All" it just says All like:
Which fields do you want to search:
[ ] All
[ ] Author
[ ] Text
[ ] Date
[ ] Etc.
Granted you could write the same thing with radio buttons or something, like:
( ) All
( ) Selected
[ ] Author
[ ] Text
[ ] Date
[ ] Etc.
But I'd say the first one makes equally as much sense to most users, especially when it selects all the other check boxes.
It's just a shortcut, in either case.

Hello Everyone,
I am trying to pass two dates to a stored procedure in SQL server. I only require the date protion of the input not the time, but I cannot seem to get the formatting to just mm/dd/yyyy
the data is collected from two text boxes on a web form and is imput as string in the format mm/dd/yyyy.
The SP is expecting datetime parameters.
I have tried so many variations to this I am wondering if it can even be done????
DateTime FromDate = DateTime.ParseExact(tempdt, "mm/dd/yyyy", System.Globalization.CultureInfo.InvariantCulture);
DateTime Todate = Convert.ToDateTime(ToDateLbl.Text);
None of these work.
All help grealy accepted.
