Event UserAddingRow

[Daniel]

Hi I have problems with the UserAddingRow event, in the child levels of the main if the property e.cancel = True does not let me leave the grid editor, even if I cancel the edition I can not leave the grid row editor, could someone help me thanks beforehand

I am running into this same problem.  Cancelling the UserAddingRow event doesn't allow me to edit any other grid.  No other control is responsive until the new row is successfully added.

Hi,

This is the default behavior (by design). Instead of canceling the event you can use the CancelAddNewRow method. Here is an example: 

private void RadGridView1_UserAddingRow(object sender, Telerik.WinControls.UI.GridViewRowCancelEventArgs e)
{
    if (e.Rows[0].Cells["Name"].Value == null)
    {
        radGridView1.MasterView.TableAddNewRow.CancelAddNewRow();
    }
}

I hope this will be useful.

Hello, if it works like this, but there will be some way that I will leave the writing in the row to add I have a help list as the user writes and I pass the focus to this to select from the list

The problem with this is that if I want to edit another cell but I do not want to add the row until the whole row is validated, it eliminates what I already put in the first cell, the 2015 version did not have this problem and I already changed to the 2017 all

Hi Daniel,

In order to leave the new row without adding it or without losing the values you will need to create a custom GridViewNewRowInfo and override the following methods:

class MyNewRow : GridViewNewRowInfo
{
    public MyNewRow(GridViewInfo info) : base (info)
    {

    }
    protected override bool OnBeginEdit()
    {
        return true;//base.OnBeginEdit();
    }
    protected override bool OnEndEdit()
    {
        return true; // base.OnEndEdit();
    }
    protected override void OnPropertyChanged(PropertyChangedEventArgs e)
    {
        if (e.PropertyName == "IsCurrent" && !IsCurrent)
        {
            return;
        }
        base.OnPropertyChanged(e);
    }
}

Change the default row in the CreateRowInfo event handler (subscribe at design time):

private void radGridView1_CreateRowInfo(object sender, GridViewCreateRowInfoEventArgs e)
{
    if (e.RowInfo is GridViewNewRowInfo)
    {
        e.RowInfo = new MyNewRow(e.ViewInfo);
    }
}

Please note that with this approach you will need to manually add the row at some point (call the EndAddNewRow method).

I hope this will be useful.
