Updating GridViewCheckBoxColumn value on another column's change

[Philippe]

Hello

I have a GridViewCheckBoxColumn column added to a GridView that serves as a visual flag about the row's update status. I want to validate and update that checkbox' ToggleState while I am in the CellEndEdit of another column (that have a Spinner editor).

This gives me a Null value on the left side. (as well as many variants thereof)

if ((ToggleState)e.Row.Cells["RegleActive"].Value == ToggleState.On)

Thanks

Hello Phillippe,

Thank you for writing.

In my tests, the value of the cell is not null and I have no problems accessing it from the EndEdit event handler triggered for a decimal column edit. Here is a sample application:

public partial class Form1 : Form
   {
       public Form1()
       {
           InitializeComponent();

           radGridView1.Columns.Add(new GridViewCheckBoxColumn("check"));
           radGridView1.Columns.Add(new GridViewDecimalColumn("number"));
           radGridView1.Rows.Add(true, 10);
           radGridView1.Rows.Add(false, 10);
           radGridView1.Rows.Add(null, 10);

           radGridView1.CellEndEdit += radGridView1_CellEndEdit;

       }

       void radGridView1_CellEndEdit(object sender, GridViewCellEventArgs e)
       {
           RadMessageBox.Show("the check box value is: " + Convert.ToBoolean(e.Row.Cells["check"].Value));
       }
   }

If you continue experiencing this behavior, please open a new support ticket where you can attach a sample project demonstrating the issue. Once we get it we will investigate it and we will get back to you with the results.

I found my error yesterday late at night. The Checkbox column is unbound, and when I initialized the values in it, I only set the checked values, not the unchecked ones. Thoses where the ones that where giving me Null errors.

foreach (GridViewRowInfo row in radGridSKU.Rows) // Boucler toutes les lignes pour mettre le checkbox correctement
            {
                if (row.Cells["ForceeClient"].Value.ToString() != "0")
                {
                    row.Cells["RegleActive"].Value = ToggleState.On;
                    row.Cells["RegleActive"].ReadOnly = false;
                }
                else
                {
                    row.Cells["RegleActive"].Value = ToggleState.Off; // <= That's the line I forgot to put in
                    row.Cells["RegleActive"].ReadOnly = true;
                }
            }

Thanks for your time
