Devexpress GridView Selected Row

I have a gridList in my c# project. There is more than 100 000 records in my gridList. I want to do some operation on filtered rows. For example I filtered gridList by 'name' column ,then I want to select all filtered rows. How can I do this?

Thank you for your help.

I find another answer for tihs problem:

void TraverseRows(ColumnView view,bool selectRemove)
{
    dtTemp = new Data.Medical.Follow.DSFollow.FollowRequestsDataTable();
    for (int i = 0; i < gridViewList.RowCount; i++)
    {
        DataRow row = gridViewList.GetDataRow(gridViewList.GetVisibleRowHandle(i));
        row["is_selected"] = selectRemove;
        dtTemp.AddFollowRequestsRow((DSFollow.FollowRequestsRow)row);
    }
}

To traverse grid rows (with grouping, sorting and filtering taking into account) use the following approach:

void TraverseRows(ColumnView view) {
    for (int i = 0; i < view.DataRowCount; i++) {
        object row =  view.GetRow(i);
        // do something with row
    }
}

P.S. Please read the Traversing Rows article for details.

First you need to set OptionsSelection.MultiSelect = true property of your GridView.

Then, to select all filtered rows you can use SelectAll() method of your GridView after applying your filter.
