checkedListbox Help Please

jamie

I am trying to figure out checkedListBoxes. I have found out through hours of searching how to display the index of the items as well as the items themselves.

int i;

string s;

s = "Checked items:\n";

for (i = 0; i <= (checkedListBox1.Items.Count - 1); i++)

{

if (checkedListBox1.GetItemChecked(i))

{

s = s + "Item " + (i + 1).ToString() + " = " + checkedListBox1.Items[i].ToString() + "\n";

MessageBox.Show(s);

what i cannot figure out is how to display information based on what is checked. like for example.

I have a list of names and each name carries 10 values that i need to print to a text file. How do i get the code to recognize the index and print the values based on what is checked? so if index 0 is checked then print x,y,z?

that is much to complicated at my level of understanding of c sharp. I just started learning this stuff. I was hoping there was a way like the regular checkboxes.. for example

if(checkbox1.Checked)

{

sw.WriteLine("some values here");

sw.Close();

}

if(checkBox2.Checked)

{

sw.WriteLine("some values here");

sw.Close();

}

so when i found out that a listcheckbox returns an index for each item, i thought there might be a simple way of using that. Like

if(index == 1)

{

sw.WriteLine("some values here");

sw.Close();

}

but i am finding out that it doesn't seem to work that way.

You can either bind your control to custom objects containing both your display value and output values and cast each selected item to your custom type, or if you just have text in the drop down, you could create a map (Dictionary to map each selected value to the output you need.

well i am trying to make a generator that will generate text. so you have choices of sky settings for a game

1. red sky

2. blue sky

3.purple sky

and if you choose one of those checkboxes, then it will use streamwriter to write to a text file the values needed to make those sky settings. So i don't want to write red, blue, purlple, i want to write a bunch of other things based on the choice. So I don't understand if what you wrote will help.

You can just loop through the checked items. For example, if you have a checkedlistbox control called ckbList, you can get the collection of checked items; each item is a string containing the text from the checklistbox item. This code will get a list of all of the checked items in a checkedlistbox control and write each checked item into a richtextbox control.

foreach (string cb in ckbList.CheckedItems)

{

rtbText.Text += cb + Environment.NewLine;

}
