Hi guys,
beforehand, i use my radtreeview without binding it to another object.
It works very nice, and i also use drag & drop facility, is very userfriendly.
No additional code needed to use this drag & drop.

and then, i use a radtreeview and bind it to datatable. the datatable has hierarchy inside it.
I use parentmember and childmember property and it works very nice.

but, when i try to use drag & drop between nodes, it becomes weird.
e.g : 
i've 5 node, A, B, C, D, E
when i try to move node C after the node A (become the second node), it move to the last node (after E).
the new position not exactly what i want.

i open the Telerik demo application for Winforms, with the chapter Treeview/Self Referencing, and i also find the same condition with my situation.
can anyone explain me about this ?

thx alot for your attention, sorry if my english is not good enouh....

Hi,

Your help manual said "You need not call merge method if you want to use menu merge in a MDI application. RadMenu automatically discovers that it is placed in a child MDI form."
 But, RadDock in my application can not merge child menu atumatically.
Please, show me how to merge menu of child form in menu of parent form.

Hello,

When you assign negative number to the textbox control  and set the property RightToLeft to true,
the minus sign appears in the right side instead of the left side as you can see at the attach image.
How can I fix it?

Thanks,

Hi,

We are changing our existing application to use RadForm and other Telerik controls to make it more UI appealing. But, I run into a problem. We had used windows UserControl very widely and now it seems like Telerik doesn't have such control that can replace windows UserControl. Could you please help me finding out some solution to this problem?

Thanks in Advance,
Prashant

Hi, guys.
I am really sorry if I am asking something that is already is answered. But I swear I tried to search for it using Google and internal forum search.

Ok, I am using RadListView control in  ListViewType.IconsView view. And I am placing my items into groups and I do show groups.

It all started when I placed many items to the list. I immediately saw that the list is displayed with vast scroll and user see only the top of the list and only the first group. So I decided to collapse all groups when I load my items into list.

/// <summary>

/// Collapses all groups in channel pair list

/// </summary>

private void CollapseAllListGroups()

{

    foreach (var group in PairControlList.Groups)

        group.Expanded = false;

}

By the way, if it is not the best way to do so - you can tell me, because I was looking for some function like "Collapse all groups" and didn't find it. If I missed it - tell me, if not - it would be good to have one already implemented for RadListView control.

Oh.. back to things. My groups all appeared collapsed, and then I saw that it is hard for user to decide where to go, since some groups might be empty and some may have hundreds of items. So, what I want to do is to display the count of items in each group on the group item. (See attached picture)
I didn't found how to do such a thing. I believe that it has to be built in functionality of  group item in RadListView. Again, if I've missed it - just tell me.
And I tried to implement it, but no success...  was thinking about changing group item text on VisualItemCreating event, but at the same time I may not know the number of items that will be placed to each group... and items will be removed/added to the groups later.

Best regards

                        if (DateTime.Now.AddDays(Properties.Settings.Default.WarningDays) >= Convert.ToDateTime(e.RowElement.RowInfo.Cells["DateEnd"].Value))
                            //if it is greater than or equal, display a red line.
                            e.RowElement.ForeColor = Color.Red;
                    } //otherwise, if the "Extended" is not equal to zero
                    else if (!e.RowElement.RowInfo.Cells["Extended"].Value.Equals(DBNull.Value))
                    {
                        //then compare with segdonyashney date have "Extended" and "DateEnd".
                        if (DateTime.Now.AddDays(Properties.Settings.Default.WarningDays) >= Convert.ToDateTime(e.RowElement.RowInfo.Cells["DateEnd"].Value) &&
                            DateTime.Now.AddDays(Properties.Settings.Default.WarningDays) >= Convert.ToDateTime(e.RowElement.RowInfo.Cells["Extended"].Value))
                            e.RowElement.ForeColor = Color.Red;
                    }
                    else
                        e.RowElement.ResetValue(LightVisualElement.ForeColorProperty, ValueResetFlags.Local);
                }
                else
                    e.RowElement.ResetValue(LightVisualElement.ForeColorProperty, ValueResetFlags.Local);
            }    
        }

It works.
But when you press the grouping and gruppiruesh on a particular column, it starts to produce the correct lines in red and those that it should be allocated.
Moreover, hide and reveal to the grouping and each time he paints in red color different rows.

And more.
In the GridView I have built a hierarchy. After grouping near the rows, press the + to see the subitems, instead udlenit write down, it hides all the items below. Shown.

1 - Normal GridView
2 - After grouping the first element is painted red, although it should not be released under the terms of
3 - If during the press groups see subitems, then the rows disappear from the bottom somewhere O_O
