How to determine index of statusStrip Item ?

Rob Sobol

I am developing a WinApp in C# in Visual Studio 2010. The parent form allows the user to open child forms.
As the child forms are opened I add an entries to the statusStrip on the bottom of my form as follows:

   statusStrip1.Items.Add("");
   statusStrip1.Items.Add("");
   statusStrip1.Items.Add("");

I need to get the index value of an item in that collection for subsequent RemoveAt, but all I know is the Text value of the item I added.

statusStrip1 is a System.Windows.Forms.StatusStrip
It has a collection of Items.
Not seeing where the Items.Add returns a value or index in the documentation.

When the user closes the child form, I would like to remove the entry from statusStrip1 but do not know how to determine the
index value so I can use the RemoveAt function.

I think it should be some variation of the following:

   statusStrip1.Items.Find("");           // no error, but not sure what code does
   statusStrip1.Items.IndexOf("")         //err on compile: invalid argument on this line, bad overload
   statusStrip1.Items.RemoveAt(0);               //works, but it removes the '0' entry, need to get the index of

Looking forward to some helpful hints on this one.

Beers on me....:-)

Thank you in advance.

Wow !
Works great !
Amazing !

Thank you for working it out. The c-sharpcorner has been helpful. I will continue to use it and hopefully I will be able to give something back as my skills improve.

Have a great day!

OK, I think you'll need to add some sort of ToolStripItem (say a ToolStripLabel) to the StatusStrip so that you can give it a name and then search on that.

Try this code:

statusStrip1.Items.Add(new ToolStripLabel() { Text = "", Name = "" });
statusStrip1.Items.Add(new ToolStripLabel() { Text = "", Name = "" });
statusStrip1.Items.Add(new ToolStripLabel() { Text = "", Name = "" });

// and then look for the second item, say

string name = "";
int index = statusStrip1.Items.IndexOfKey(name);
if (index >= 0)
{
statusStrip1.Items.RemoveAt(index);
}

Thank you for your help.

The end user is selecting options from a pull down menu. Each option opens a new child form. They are added in the order the end user selects to statusStrip1, potentially a different sequence each time. When they close out a particular child form the parent form receives the name of the form. I want the parent form to then remove that entry from statusStrip1.

Your solution returned an Out of Range error. I think you are parsing the string variable 'find' for a portion of itself in the line
int index = int.Parse(find.Substring(1, find.Length -2).Substring(4)) - 1;
I need to search the statusStrip1 collection to find the index that related to the string in the variable 'find' in your example.

If you're adding them sequentially like that, then you can deduce the index from the text.

For example:

string find = "";
int index = int.Parse(find.Substring(1, find.Length - 2).Substring(4)) - 1;
statusStrip1.Items.RemoveAt(index); // removes item at index 1
