Add New Row to xtragrid View - devexpress

Question

I have created Xtragrid in which i have added RepositoryItemLookUpEdit at run time but the problem is when i add a new row by using View.AddNewRow(); a new row is added with empty cell. So i need to add RepositoryItemLookUpEdit in new created row. Can any body help me ?

Answer 1

I had the same issue. You need to use a datasource that implements IBindingList, such as BindingList and also set AllowNew = true

Answer 2

Where do you bind the data?
Can I suggest you implement the following ex and see where the problem starts?
Start with a grid and button on the form. I created the repository item in the designer
private void Form1_Load(object sender, EventArgs e)
{
DataTable dt = new DataTable("newTable");
dt.Columns.Add("1", typeof(Int32));
dt.Columns.Add("2", typeof(bool));
dt.Columns.Add("3", typeof(Int32));
dt.Rows.Add(1, true, 12);
dt.Rows.Add(2, false, 32);
dt.Rows.Add(3, true, 42);
gridControl1.DataSource = dt;
gridView1.Columns[0].ColumnEdit = repositoryItemCheckEdit1;
}
private void button1_Click(object sender, EventArgs e)
{
gridView1.AddNewRow();
}
It adds a new row with a repository item in the 1st column :)

Answer 3

I always add one more item in data source, for example:
private void AgregarDetalle_Click(object sender, EventArgs e) {
var list = GridOpcionDetalle.DataSource as List<DetalleOpcion>;
list.Add(new DetalleOpcion());
GridOpcionDetalle.DataSource = list;
GridOpcionDetalle.RefreshDataSource();
}

Private Sub grdInvoice_EditorKeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles grdInvoice.EditorKeyDown
Dim dt As New DataTable
Dim dr As DataRow
Dim i As Integer
With GridView1
.OptionsNavigation.EnterMoveNextColumn = True
If e.KeyData = "13" Or e.KeyData = "9" Then
If .FocusedRowHandle.ToString = .RowCount - 1 Then
If .FocusedColumn Is .Columns("Rate") Then
If .GetRowCellValue(.RowCount - 1, "Qty") <> "0" And .GetRowCellValue(.RowCount - 1, "Rate") <> "0" And .GetRowCellValue(.RowCount - 1, "ItemCode") <> "" Then
dt.Columns.Add("No")
dt.Columns.Add("ItemCode")
dt.Columns.Add("ItemName")
dt.Columns.Add("Qty")
dt.Columns.Add("Rate")
dt.Columns.Add("Amount")
dt.Columns.Add("Unit")
For i = 0 To .RowCount - 1
dr = dt.NewRow
dr("No") = .GetRowCellValue(i, "No")
dr("ItemCode") = .GetRowCellValue(i, "ItemCode")
dr("ItemName") = .GetRowCellValue(i, "ItemName")
dr("Rate") = .GetRowCellValue(i, "Rate")
dr("Qty") = .GetRowCellValue(i, "Qty")
dr("Amount") = .GetRowCellValue(i, "Amount")
dr("Unit") = .GetRowCellValue(i, "Unit")
dt.Rows.Add(dr)
Next
dr = dt.NewRow
dr("No") = .GetRowCellValue(i - 1, "No") + 1
dr("ItemCode") = ""
dr("ItemName") = ""
dr("Rate") = "0"
dr("Qty") = "0"
dr("Amount") = "0"
dr("Unit") = ""
dt.Rows.Add(dr)
grdInvoice.DataSource = dt
.FocusedRowHandle = i
.FocusedColumn = .Columns("ItemCode")
End If
End If
End If
End If
End With
