Hi,
Migrate from 2010v1 to 2025v2 399 in ASP.NET WebForms NET Framework 4.8.1.
Using C1GridView from C1.Web.Wijmo.Controls.48.dll
Dont exists event OnGroupColumnMoved
GroupAreaVisible property does not exists.
My markup OLD code:
OnGroupColumnMoved="C1GridView1_GroupColumnMoved"Not exists OnGroupColumnMoved
Legacy spaguetti code 2010v1 version:
protected void C1GridView1_GroupColumnMoved(object sender, C1GridViewColumnMoveEventArgs e)
{
if (C1GridView1.GroupedColumns.Count == 0)
{
#region Without grouping fields
//Save old filters
Object[] b = new Object[C1GridView1.Columns.Count];
C1BaseFieldCollection col = C1GridView1.Columns;
col.CopyTo(b, 0);
//Reconfigure grid structure
C1GridView1.Columns.Clear();
ConfigureGridViewColumns(int.Parse(Session["reportID"].ToString()));
//Apply filters
for (int i = 0; i < C1GridView1.Columns.Count; i++)
{
for (int j = 0; j < b.Length; j++)
{
if (C1GridView1.Columns[i].GetType() == typeof(C1BoundField))
{
if (((C1BoundField)C1GridView1.Columns[i]).DataField == ((C1BoundField)b[j]).DataField)
{
((C1BoundField)C1GridView1.Columns[i]).FilterValue = ((C1BoundField)b[j]).FilterValue;
break;
}
}
}
}
//Get datasource of grid
C1GridView1.DataSource = Web.Util.GetGridFilterByFieldType(C1GridView1, _dataSources.Tables[0], GetConfigurationParameter(ConfigurationParamType.DefaultDatetimeFormatString), null);
C1GridView1.DataBind();
#endregion
}
else
{
#region Add or change grouping field
//Grouping field
C1BoundField fieldGroupBy = (C1BoundField)(((C1.Web.Wijmo.Controls.C1GridView.C1GridViewColumnMovedEventArgs)(e)).Column);
if (C1GridView1.GroupedColumns.Count > 1)
{
//If there are two grouping fields, then delete and add only last grouping field selected
C1GridView1.GroupedColumns.Clear();
C1GridView1.GroupedColumns.Add(fieldGroupBy);
}
//Apply order by grouping field
C1.Web.Wijmo.Controls.C1GridView.C1GridViewSortEventArgs s = new C1GridViewSortEventArgs(((C1BoundField)fieldGroupBy).SortExpression, ((C1BoundField)fieldGroupBy).SortDirection);
C1GridView1.DataBind();
C1GridView1_Sorting(C1GridView1, s);
#endregion
}New events in 2025v2:
OnColumnMoved="C1GridView1_ColumnMoved"
OnColumnMoving="C1GridView1_ColumnMoving"I try add ColumnMoved event:
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
//C1GridView1.GroupColumnMoved += new C1GridViewGroupColumnMovedEventHandler(C1GridView1_GroupColumnMoved);
C1GridView1.ColumnMoved += C1GridView1_ColumnMoved;
//C1WebReport.ReportError += new C1.C1Report.ReportEventHandler(C1WebReport_ReportError);
}
private void C1GridView1_ColumnMoved(object sender, C1.Web.Wijmo.Controls.C1GridView.C1GridViewColumnMovedEventArgs e)
{
throw new NotImplementedException();
}ColumnMOved event not handled in console?
any full samples using columns moving and working when I moved column A, then move column B, etc?
OnColumnMoved and OnColumnMoving events ?
thanks all!
