Sorting based on Boolean Column

[Erik]

Hi,

I added boolean column to the grid. Is it possible to sort it so the boolean with tick will be at the top position? I tried but failed.
Thanks so much

Second: I got 10 columns and ReadOnly=True for column 0-5. I figured out that I cannot sort from column 6-9, Am I wrong? If i make them readonly=false, I can sort from any column.

Third: my grid is not bound to dataset, I enable the tick in BOOL Column but if i sort it the tick is gone. What happen?

Thanks for all your help.

Hi eriksurya,

Thanks for the feedback.

Currently we do not offer support of unbound columns in RadGridView. In Q2 release we will add events and  API to work in unbound mode. Sorry for the inconvenience.

Please change your business logic and use the IBindingList object. If you continue to have a problem, please send us a simple project.

Hi eriksurya,

you can add a memory DataTable object with bool type columns or BindingList<T> object, where the T object has some bool property. I hope the following snippet will be helpful:

DataTable table = new DataTable();

table.Columns.Add("Column1");
table.Columns.Add("Column2");
table.Columns.Add("Column3",typeof(bool));

DataRow row = table.NewRow();
row["Column1"] = "1";
row["Column2"] = "2";
row["Column3"] = false;
table.Rows.Add(row);

row = table.NewRow();
row["Column1"] = "4";
row["Column2"] = "5";
row["Column3"] = true;
table.Rows.Add(row);

gridView.DataSource = table;

public class Customer
{
    private string name;
    private string address;
    private double sum;
    private bool active = true;

    public bool Active
    {
        get { return active; }
        set { active = value; }
    }


    public string Name
    {
        get { return name; }
        set { name = value; }
    }


    public string Address
    {
        get { return address; }
        set { address = value; }
    }

    public double Sum
    {
        get { return sum; }
        set { sum = value; }
    }


}

BindingList<Customer> customers = new BindingList<Customer>();
Customer cust = new Customer();
cust.Name = "Ivan Petrov";
cust.Address = "Kalinka 6";
cust.Sum = 5500;
customers.Add(cust);

gridView.DataSource = customers;

Kind regards,
