Filter in Hierarchical Grid

[Darko]

Hi, 

i am looking at the Samples for the latest Release (Q2 2011 SP1) of the tools and 
I found the GridView/Custom Filtering sample very usefull.
However, my Grid is bound to the Data using the  AutoGenerateHierarchy feature.
The Grid is bound to  the BindingSource which is bound to a BindingList<T> which
is basically 3 Levels deep. The binding works great... I get 3 levels hierachical Grid.

I would love to apply the mentioned sample of Custom Formatting to the whole Grid Data,
e.g. the Text entered in the Filter TextBox should be searched in each Column and in each Row in every Level
of the hierarchy. Is that possible? If not, do you have a suggestion for me how to filter the Grid without
drilling down manually in every Level of it?

Thanks and best regards,
Darko

Hi Darko,

You can use the codebase from our Demo Application to make a custom filtering to the all levels in hierarchy mode. The CustomFiltering event is raised for every GridViewTemplate. The important thing in this scenario is to call Refresh method of MasterTemplate to cause event firing for every text change:

private void filterTextBox_TextChanged(object sender, EventArgs e)
{
    this.radGridView.MasterTemplate.Refresh();
}

Do not hesitate to contact us if you have further questions or issues.
