Getting CheckBoxList Item values

Question

I have a CheckBoxList which I m populating with data  When I attempt to retrieve the checked items from the list I can only grab the item ordinal  I cannot get the value   I ve read that you can use Items i  Value however when I try to do this I get an error stating that there is no extension method  value    Here s the code I m using to try and grab the information  note the GetItemText i  actually only gives me the item position  not the text for the item      private void btnGO Click object sender  EventArgs e        for  int i   0  i  lt  chBoxListTables Items Count  i                  if  chBoxListTables GetItemChecked i                         string str   chBoxListTables GetItemText i               MessageBox Show str                  next line invalid extension method             chBoxListTables Items i  value                      This is using  Net 4 0  Any thoughts would be appreciated   thanks

You can try this -  string values       foreach ListItem item in myCBL Items   if item Selected    values    item Value ToString                values   values TrimEnd          To eliminate comma in last

Try to use this           for  int i   0  i  lt  chBoxListTables Items Count  i                          if  chBoxListTables Items i  Selected                                string str   chBoxListTables Items i  Text                  MessageBox Show str                    var itemValue   chBoxListTables Items i  Value                            The  V  should be in CAPS in Value   Here is another code example used in WinForm app and runs properly           var chBoxList  new CheckedListBox            chBoxList Items Add new ListItem  One    1             chBoxList Items Add new ListItem  Two    2             chBoxList SetItemChecked 1  true            var checkedItems   chBoxList CheckedItems          var chkText     ListItem checkedItems 0   Text          var chkValue     ListItem checkedItems 0   Value          MessageBox Show chkText           MessageBox Show chkValue

Instead of this   CheckboxList1 Items i  value    Try This   CheckboxList1 Items i  ToString      It worked for me

This ended up being quite simple  chBoxListTables Item i  is a string value  and an explicit convert allowed it to be loaded into a variable  The following code works   private void btnGO Click object sender  EventArgs e        for  int i   0  i  lt  chBoxListTables Items Count  i                    if  chBoxListTables GetItemChecked i                         string str    string chBoxListTables Items i               MessageBox Show str

You can initialize a list of string and add those items that are selected    Please check code  works fine for me   List lt string gt  modules   new List lt string gt      foreach ListItem s in chk modules Items        if  s Selected                 modules Add s Value

This will do the trick for you  foreach  int indexChecked in checkedListBox1 CheckedIndices        string itemtxt   checkedListBox11 Items indexChecked      It will return whatever string value is in the checkedlistbox items

to get the items checked you can use CheckedItems or GetItemsChecked  I tried below code in  NET 4 5  Iterate through the CheckedItems collection  This will give you the item number in the list of checked items  not the overall list  So if the first item in the list is not checked and the second item is checked  the code below will display text like Checked Item 1   MyListItem2     Determine if there are any items checked   if chBoxListTables CheckedItems Count    0            looped through all checked items and show results      string s           for  int x   0  x  lt  chBoxListTables CheckedItems Count  x                  s   s    x   1  ToString             chBoxListTables CheckedItems x  ToString                    MessageBox Show s    show result     -OR-  Step through the Items collection and call the GetItemChecked method for each item  This will give you the item number in the overall list  so if the first item in the list is not checked and the second item is checked  it will display something like Item 2   MyListItem2   int i    string s     s    Checked items  n      for  i   0  i  lt  checkedListBox1 Items Count  i             if  checkedListBox1 GetItemChecked i                  s   s    Item      i 1  ToString             checkedListBox1 Items i  ToString       n                MessageBox Show  s     Hope this helps
