We are going through the following C# code to analyze the process of validating data in grid cell.The C# code snippet will enable the data cell validation in a textbox column for entering only none empty strings, which will disable the data validation and display the error indicator at the row header.We would not want the Cell Value Changed event firing every single time a letter was added to a person’s last name.Still, it doesn’t make much sense when we think about the way Check Box’s work, in that, they can only ever be On or Off, and that once you have made your selection, you’re probably pretty confident that you want to change the value.Any solution is going to involve using an event that definitely will fire to stop the Data Grid View from thinking it’s in edit mode.
In this case, you need to add a Combo Box to the cells in the desired column. Data Source = bindingsource '---add a combobox column to the Data Grid View control--- Data Grid View1. Add(combo Box Col) The previous code showed how you can bind a Binding Source control (containing a list of items to let the users choose) to a Data Grid View Combo Box Column control inside a Data Grid View control. Add("Price", "Price") '---create a new bindingsource control--- Dim bindingsource As New Binding Source '---add the items into the control--- bindingsource. Header Text = "Types" '---data bind it--- combo Box Col. Before we validate data to grid cell, we need to cancel the Validate Cell event to prevent the users from exiting the cell until entering a valid editor value or cancelling the edit process.Meanwhile, we can use the Validate Row event in the same way to prevent the user from exiting the current row.
