<dx:ASPxCheckBoxList ID="checkBoxList" runat="server">
<Items>
<dx:ListEditItem Value="1" />
<dx:ListEditItem Value="2" />
<!-- ... -->
</Items>
</dx:ASPxCheckBoxList>
<dx:ASPxButton runat="server" ID="ClickButton" Text="Click" OnClick="ClickButton_Click" />
protected void ClickButton_Click(object sender, EventArgs e)
{
var selectedValues = checkBoxList.SelectedValues;
var selectedItems = checkBoxList.SelectedItems;
var selectedIndices = checkBoxList.SelectedIndices;
// ...
}
Protected Sub ClickButton_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim selectedValues = checkBoxList.SelectedValues
Dim selectedItems = checkBoxList.SelectedItems
Dim selectedIndices = checkBoxList.SelectedIndices
End Sub
If the SelectedItems property returns null, make sure that you set the ValueType property to an .NET type that matches the ValueField column type. Otherwise, the editor cannot find the corresponding item because the editor’s ValueType property does not match the item type (String by default).
