The following code works:
view.ColumnGroups.Add(new GridViewColumnGroup("AutoPOD"));
view.ColumnGroups.Add(new GridViewColumnGroup("Addresses"));
view.ColumnGroups[0].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[0].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[1].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[1].Rows.Add(new GridViewColumnGroupRow());
Is there a way to replace it with something like this, short of using variables:
view.ColumnGroups.Add(new GridViewColumnGroup("AutoPOD"));
view.ColumnGroups.Add(new GridViewColumnGroup("Addresses"));
view.ColumnGroups["autoPOD"].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[0].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups["Addresses"].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[1].Rows.Add(new GridViewColumnGroupRow());
We have a lot of groups and having the name right there would help code readability a lot.
Thanks,
Joe

Hi All
I have implemented the gantview in a test winforms application, and I am just wondering if someone can assist me.
On the View, I drag a Task (Child) Item, and thus changes the start or end date.
Now a very Basic need, is that the Summary (Parent) gets updated too.
Here is a toned down version:
void radGanttView1_SelectedItemChanged(object sender, GanttViewSelectedItemChangedEventArgs e)
{
try
{
if (e.Item.End > e.Item.Parent.End)
{
e.Item.Parent.End = e.Item.End;
}
if (e.Item.Start < e.Item.Parent.Start)
{
e.Item.Parent.Start = e.Item.Start;
}
}
catch { }
}
(View1)
Now this "WORKS" in the sense that if I click off the selected child (View2) , and then back on to it, the Summary does update (View3), but I need it to be immediately
Regards

Hi, I got an issue with the RadMaskedEditBox with standard phone mask (999) 000-0000. It works well when we enter only digits, but when we hit the keys like 123123-1234, the '-' skips the next character so I got text like this "(123) 123-_123". I'm not really familiar with telerik controls and I tried to find some way to avoid this without success. So is there a property or something else to avoid this problem or is there a real issue with the control itself.
Thank you very much.

Hi Support,
I change my export to excel function to be able to have xlsx format instead of xls. So I change my ExportToExcelML to use GridViewSpreadExport function.
Everything works properly except the group column start in column B instead of column A. My users prefer when the data start in column A. You can see the difference between the old and the new format.
Is it possible that the group column start in column A like it was before?
Regards,
Nadia

Hopefully the attached screenshot will show the issue I am having. It is intermittent but when I start typing on a multicolumn within a grid (and I think I have seen this with the stand alone multicolumn as well), the drop down pops but the scroll bar is initialized at the bottom of the list. When this occurs, I am also unable to use my up/down arrow keys to navigate the drop down list so it is quite annoying.
This is on 2016 Q1.

Hello,
1. I added a grouping expression to my RadGridView, but the GridViewCheckBoxColumns no longer automatically become checked when all of the child rows in each group for that column are checked. How can I regain this functionality?
2. Also, is it possible to add header checkboxes that only apply to the groups? I have my GridViewCheckBoxColumns that apply to the entire column, but what if I just want to check/uncheck all the rows in a particular group?
Thanks!

I have a radgridview that is databound to a llblgen entity collection (implements IListSource) . One property of the actual databound object (entity) is a nulalble int. This property is set by a GridViewComboBoxColumn. When a new entity is added to the llblgen entity collection after the llblgen entity collection is databound to the radgridview the new row is automatically added to the radgridview but when the user changes the nullable property a NullReferenceException occurs:

Good day all
I just started playing around with the GantView in an existing Winforms application.
In general All seems to be working nicely, but I have 1 serious issue I cannot seem to get around.
On the context menu, when I am over a link, and select delete, It deletes the Parent/Child/sibling item. I have checked the forums and googled it , but can not find a way so far to simply just delete the link, and not any items.
Any links/samples/advice on how this can be achieved would be appreciated.
Regards
Marius

Hello
I would like to remove the top and bottom border of each ribbon group at run time for a cleaner look. Have tried this in the form constructor with no success. Any ideas?
Dim myRibbonBarTab As RibbonTab = CType(Me.RadRibbonBar1.CommandTabs(0), RibbonTab)
For Each group As RadRibbonBarGroup In myRibbonBarTab.Items
group.GroupBorder.BoxStyle = BorderBoxStyle.FourBorders
group.GroupBorder.TopWidth = 0
group.GroupBorder.BottomWidth = 0
Next
Thanks for any tips that point me in the right direction.
Robert
