Re: How to disable a ListViewItem?

It is pretty clear that what Enabled and Disabled mean. As you mentioned , Disable items must look Gray and could not be selected. Also their Click, Doubleclick and other such events must not be triggered.

Since MS didn't include an Enabled property for LVItems, it seems it isn't "pretty clear" what you consider a disabled item to be.
ListViewItems are no controls on their own behalf, just like TreeNodes they are dependent from their containing parent control. Thus, Enabled does not have an inherent meaning by itself for child elements of controls.
You'll have to implement whatever meaning you want "Enabled" to have on your own.

"Their Click, Doubleclick and other such events" doesn't make sense, either - a LVItem doesn't fire these events, its containing ListView does.
So if you want a ListView that can handle additional properties for its Items, you'll have to roll your own (i.e. derive from ListView and catch the appropriate events).

Mav is dead on with his response. In order to do this, you'd have to roll your own ListView and ListViewItem classes to expose this kind of functionality.

If you don't want to do that, you could always just remove the disabled items from the ListView.

You really should read up on Windows GUI design guide. In there, it'll tell you why what you're doing is a bad idea. Something about a "consistant user experience". A ListView control is expected to provide a list of valid and selectable items. Turning off some items is an unexpected behavior for the control, thereby leading to confusion about how the control really works.

Hi,
in the gridview's datarowbound event you can seach checkbox from e.row.findcontrol["chkboxName"]
and then you can check if from database value is true then chkBox.Checked = true;

Hi
I have created custom controls like listbox, spinbox, textbox and treeview controls
And we are handling mouse wheel msg strategy through strategy design pattern .
Problem is when form has scrollbars and when we scroll on tree view control
Then form also gets scrolled which is not required i.e, if I scroll treeview only treeview must scroll not the parent.
So how to stop this, could your suggest me a solution for this.

I want to replace Dash with a period only once in a string like

ABC-XYZ =ABC.XYZ

ABCXYZ =ABCXYZ (No Replace)

ABC-X-Y-Z =ABC.X-Y-Z

A-BC-XYZ =A.BC-XYZ

ABCXYZ- =ABCXYZ.

I found where the first dash is match using of IndexOF property of string.
And RegEx.Replace replace all the found characters I want to replace only first occurrence.
But how I can replace only once...?

write your own function, use loop, if character found then replace and then break or return.

string str = "ABC-X-Y-Z";
int index = str.IndexOf("-");
str = String.Format("{0}{1}{2}", str.Substring(0, index), ".", str.Substring(index + 1, str.Length - index - 1));

Hope it helps.

Thanks for your reply.

But it will give error in case of

string str = "";

Because this input is depend upon the end user So I can-not say the input data in Correct format.

Or if dash is not found then it will also give the error.

I make new code please let me know this is Ok or not...?
**************************************************************
public static string getNewItemName(string actualItemName, string saparaterCharacter)

{

valueToReturn = actualItemName.ToString();
else

string strFirstPart = actualItemName.ToString().Substring(0, ipos).ToString();
