问题 I have a CheckedListBox and I would like to check all the items that are in another List. This code does not work since the CheckedItems property is read-only and the types do not match, but it gives the best idea of what I want to do. checkedListBox1.DataSource = DataSetSelectAll().Tables[0]; checkedListBox1.ValueMember = "id_table"; checkedListBox1.DisplayMember = "name"; List<tableClass> list = MyCheckedList(); checkedListBox1.CheckedItems = list; I know this is wrong but do not know how

I want to have a button that once clicked, it will select all checkboxes in my checklistbox. I've search the possible answers but I always see examples for asp.net and javascript. I am using Windows form in c#. Thank you for any response. for (int i = 0; i < checkedListBox1.Items.Count; i++) { checkedListBox1.SetItemChecked(i, true); } Call a method from code behind in C# and write this piece of code, then you could be able to check/uncheck them. This checks or uncheck all the check boxes present in the checkboxlist. Hope it might help. foreach (ListItem item in CheckBoxList.Items) { item

Limiting checked items of TCheckListBox on Delphi

问题 I want to limit a TCheckListBox. I desire only 2 items should be checked, and all unchecked items will be disabled and grayed. Since the checked / unchecked items are dynamic, i can not use a static itemIndex. Here is what i tried, but i got "Out of chip bounds" error. On click event of my CheckListBox ; var NumberOfCheckedItems, I: Integer; begin NumberOfCheckedItems := 0; for I := 0 to CkLst1.Count - 1 do begin if CkLst1.Checked[I] then NumberOfCheckedItems := NumberOfCheckedItems + 1; end;

Getting CheckBoxList Item values

由 不羁的心 提交于 2019-11-30 18:42:35
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 < chBoxListTables.Items.Count; i++) { if (chBoxListTables

问题 In C#, I am trying to Check an item in a CheckBoxList where the text equals what I require. I would modify the code to check items that exist in the database.
