I have been scouring the internet for days looking for ways to check items in a checkedlistbox based on an array of strings.
After finding bits and pieces of the solution, and translating some code from VB.NET, I finally created something that is extremely short, efficient, and completes the job.
//This code takes a string and splits it up based on a comma delimiter.
//You can use any kind of string array you want,
//just be sure that your strings match the items in your list box!
string[] yourStringArray = yourObject.yourAttribute.Split(',');
//The foreach iteratures through your array.
foreach (string strToFind in yourStringArray)
{
//This code finds the index of the string. It will return -1 if it doesnt find it
int itemIndex = yourCheckedListBox.FindString(strToFind);
//This code provides a safe guard in case it cant find your string
if (itemIndex != -1)
{
//This code will actually 'check' the item at the index specified,
//based on the index previously found
yourCheckedListBox.SetItemChecked(itemIndex, true);
}
}
Applications: If your storing previous checked options as one long string, this is easy code to 'recheck' those items, and is exactly what I'm using it for.
Also, using "Select All ---" type of buttons would be a great application ff you have a LOT of items to choose from and you want to allow a user to check all of a certain type, etc.
