[Solved] Group Row Data

[Chapman Mays]

I have several questions about how to display data on a group row. First, I have a data member in my object that is not displayed in the grid, but can be used to group the elements in the grid using a external button using the 2nd solution found here: Custom Group Row Based On Column.

As in the solution above, I want to display aggregate information only if it is grouped in this way and use the default grouping for all other groups.

1. Part of the aggregate information I want to display is information from the first row of data because as turns out these would be the same for similarly grouped items. I figured I could use the FirstFunction aggregate with the appropriate source field, but when I run it, it displays the name of the class (like it is calling ToString() on the class instead of the field). How can I display this information correctly?
2. I don't want to display the default group header when grouped in this way. Since the column doesn't actually exist in the grid, I can't use the GroupHeaderFormatString property. How can remove the default header or possibly use a different column to display a value?
3. Since I don't have a header, I would like the aggregate information to be displayed left aligned and preferable vertically aligned as well. How is this possible?

I'm using version 2009.2.812.1030 of the controls.

Thanks,

Chapman

Hello Chapman,

You can use the GroupRowStyle property of RadGridView to define a new style for the GridViewGroupRow. It contains of an expander which header is the place where the aggregate functions get displayed.
