Hello,
I've developed an application using winForm Q1 2010 (on VS2008, .Net3.5);
Today I've installed the version Q2 2010 SP2, but I've found some differences.
#Question1:
In version 2010 Q1 the gridview was very smart:after re-assigning the datasource, the grid remembers the "old" selected
row and automatically re-select the row.
In the new version(2010 Q2 SP2) this behaviour seems different, the grid selects the first row.
Do you have changed something about that? How can I re-activate the behaviuor?
#Question2:
Following this page (http://goo.gl/PM8T) I've "upgraded" my app (1 solution, 5 projects, about 20 grids),
but now some grids (not all of them!!) have lost the settings (e.g. the showRowHeaderColumn property)and the skin: did you have ever seen something like that?
I really can't find any differences in the grids (all of them have the same properties).
I've readed this forum, founding nothing about: do you have any advice for me?
Thanks in advance
Francesco

I know this question has been answered many times before, but none of those replies are working for me.
I have a GridView with a TextBox column. Under specific circumstances, the TextBox column becomes a DropDown list. I have this part working fine.
I bind the DropDownList to a List<T> where T is an object, say CustomerType for example. Normally, I would bind the DisplayMember to the "TypeName" property and the ValueMember to the "CustomerTypeId" property and all would be well.
But because the TextBox column is bound to the "TypeName" of the object instead of the Id, I need some code to get the Id from the combobox.
I tried adding code to the ValueChanged event, but I am always getting the wrong element. Here is my code:
Any tips?

Hello,
I work with radGridView in unbound mode and every time I add a column I want to add a Tag to it, indicating the object that the column derives from. However, there is no such property as Tag for columns. Is there a possible way to achieve this, like binding a property or something like this? I tried to add the object's key in gridView.Columns[index].Name property, but this has as a result the uniqueness of the columns. Please help.
Thank you in advance

Hi Guys,
I am using the document tab strip within which I have 2 tabs.The requirement is that the user cannot swap the tabs.
I prevented that by setting AllowDragDrop=false for the document tabstrip.
However when the user drags a tab, the tabstrip hints where the drop will appear by showing visual pointers in between tabs.How do I prevent this scenario.
Any help would be appreciated.
I am using Visual studio 2008.
