Check box cells update only after moving rows :(

[chris petropoulos]

Hi guys,

Im sure there is some obvious im missing, but the problem i have is that i have a grid with 3 columns. Column 1 has report name, Column 2 - a checkbox column to 'show' that report, Column 3 - a checkbox column to 'hide' that report. So if a user clicks the checkbox in 'Show' column, i want to uncheck the 'Hide' checkbox column (ie column 2) and vice versa. The code below handles it, however the grid only refreshes the change once i move off the current row... So what do i need to call so that the cells or row is repainted instantly once this code runs? Also should i instead use the CellValueChanged event? coz that didnt seem to work, hence why i chose this event here. Also do i even need to call BeginEdit and EndEdit here? Im not quite sure when those methods should be used.

Thanks for your advice :-) Chris.

private void gridReport_ValueChanged(object sender, EventArgs e)
        {
            RadCheckBoxEditor editor = (RadCheckBoxEditor)sender;
            editor.BeginEdit();
            SUB_REPORT report = (SUB_REPORT)gridReport.CurrentCell.RowInfo.DataBoundItem;
            if (gridReport.CurrentCell.ColumnIndex == 1) // show column
            {
                if ((bool)editor.Value)
                {
                    report.Hide = false;
                }
            }
            else
            {
                if ((bool)editor.Value)
                {
                    report.Show = false;
                }
            }
            editor.EndEdit();           
        }

Hello chris petropoulos,

You can use the following code in this case:

void radGridView1_ValueChanged(object sender, EventArgs e)
{
    RadCheckBoxEditor editor = sender as RadCheckBoxEditor;
    if (editor != null)
    {
        GridViewDataColumn column = (GridViewDataColumn)this.radGridView1.CurrentColumn;
        if (column.UniqueName == "Bool")
        {
            this.radGridView1.CurrentRow.Cells["Bool2"].Value = !(bool)editor.Value;
        }
        if (column.UniqueName == "Bool2")
        {
            this.radGridView1.CurrentRow.Cells["Bool"].Value = !(bool)editor.Value;
        }
    }
}

You don't have to call BeginEdit or EndEdit methods. These methods are used to open or close the editor thru code. In addition the following KB article demonstrates how to place radio buttons in a single cell. I hope it helps.

Kind regards,
