[Solved] Grouping and Column access

[Markus]

Is it possible to find out which group are currently open and what is the value of the group (I look for some kind of a "GroupHeader" collection)?

All rows in a grid are available in "Items" collection. There I can access the value of each column with "Cells" collection. Is it possible to access such a cell by UniqueColumnName?

When I expand a group the group collapses again on a rebind, how can I avoid this behavior?

After expanding a group I press on a button in "CommandItemTemplate" of grid. The result for "Visible" property for all items is always "0". So how can I find out which rows in the group are currently visible (maybe this has something to do that groups always collaps automatically)?

Hi Markus,

You can get any grid item using GetItems method, you can find more details here.

As for keeping the expanded state of RadGrid groups when rebinding the grid -- I hope this code library will help:

Thanks for help I get it work.

There is one remainig question. I use "Items" collection to get data for a row. Can I access the cells collection for an item by UniqueColumnName somehow to get a value or is access only possible by index?

Hi Markus,

It is recommended accessing the cells by the column UniqueName. Here is an example:

item("ColumnUniqueName").Text or item("ColumnUniqueName").Controls

You can find more details in this help topic. However, this is not applicable for GridGroupHeaderItems, it does not have a cell for each column.
