errors when migrating from Q1 SP2 to Q2

[shortie]

We got these errors when trying to upgrade our Q1 SP2 projects:

1. no 'VisualElement' property

GridViewRowInfo r = radGridView.Rows[i];

r.VisualElement.ForeColor = System.Drawing.Color.Red;

2. no 'CellElement' property

GridViewCellInfo gvci = radGridView.Rows[i].Cells[0];

GridCheckBoxCellElement gcbce = (GridCheckBoxCellElement)gvci.CellElement;

3. no 'Owner' property

var col = (GridViewDataColumn)cell.ColumnInfo;

col.OwnerTemplate.Owner;

Please help us to fix the above errors. Thanks in advance.

Hello ChunChang,

Thank you for your feedback:

1. We removed the VisualElement property because many of our customers used it in a wrong way. This property was safe to be accessed only when handling the RowFormatting event. In fact you can use it only for testing purposes. You should handle RowFormatting event instead. For example:

void radGridView1_RowFormatting(object sender, RowFormattingEventArgs e)
{
    if ((int)e.RowElement.RowInfo.Cells["ID"].Value > 10)
    {
        e.RowElement.ForeColor = Color.Red;
    }
    else
    {
        e.RowElement.ResetValue(LightVisualElement.ForeColorProperty, ValueResetFlags.Local);
    }
}

2. The same applies for the CellElement property. However, you can still get the cell and row elements by using GridTableElement.GetRowElement and GetCellElement methods:

GridRowElement rowElement = this.radGridView1.TableElement.GetRowElement(this.radGridView1.Rows[5]);
GridCellElement cellElement = this.radGridView1.TableElement.GetCellElement(this.radGridView1.Rows[5], this.radGridView1.Columns["Name"]);
//...

3. In the new RadGridView the data layer is a separate component that could be used without a UI. It doesn't know about the RadGridView control at all. That's why we removed the Owner property. Please describe the situation where you need access to the control. We will try to find a solution.

I am looking forward to your reply.
