Hi Support Team,
I have used an UltraCombo control where i have added a checkbox style column for which i have binded the column to the CheckedListSettings.CheckStateMember. As per your sample for multi-select, you have provided an event for ICheckedItemList.checkstatechanged, but this fire after checkstate is changed. What we require here is that we validate data before checkstate is changed, if validation fails then we would like to cancel the event to avoid checkstate getting changed.
For e.g. In DisplayLayout initially the checkbox was false and when i check it and i want to validate before set to true, if validation fails it should simply cancel the event and set checkbox to false.
Hi,
No, there's no way to do this. But why don't you disable the rows you don't want the user to change? The InitializeRow event would be a good place to do this.
