RadGridView1.ChildrenOfType<GridViewRowItem>()

[Orit]

Hello

I want to search for a value in one of the columns in my grid and then select the row
I used this code to run on the items

foreach (GridViewRowItem griParent in RadGridView1.ChildrenOfType<GridViewRowItem>())
                    {
                        if (griParent.DataItem != null)
                        {
                            if ((griParent.DataItem as DataRowView).Row["ActivityName"].ToString().Contains(sSearch))
                            {
                                gvriParent.Add(griParent);
                            }
                        }
                    }
..........

if (iParentSearch < gvriParent.Count)
                {
                    if ((gvriParent[iParentSearch] as GridViewExpandableRow) == null && ((gvriParent[iParentSearch].ParentOfType<GridViewExpandableRow>()))!=null)
                    {
                        ((gvriParent[iParentSearch].ParentOfType<GridViewExpandableRow>())).IsExpanded = true;
                    }
                    gvriParent[iParentSearch].IsSelected = true;
                    this.RadGridView1.BringDataItemIntoView(gvriParent[iParentSearch]);
                    iParentSearch++;
                }
......

the problem is
that if there is a scroll in my grid
the "foreach (GridViewRowItem griParent in RadGridView1.ChildrenOfType<GridViewRowItem>())   "
does not get the rows that are not shown in the screen

by the way
I use - this.RadGridView1.BringDataItemIntoView
but it looks like nothing happen

Thanks

Hello Orit,

You can achieve your goal using ItemContainerGenerator instead:

Hi

Thanks for the quick reply
I tried to use ItemContainerGenerator 
but I get an error under it

foreach (object item in RadGridView1.Items)
                   {
                       GridViewRow griParent = RadGridView1.ItemContainerGenerator.ContainerFromItem(item) as GridViewRow;

Error 200 'Telerik.Windows.Controls.RadGridView' does not contain a definition for 'ItemContainerGenerator' and no extension method 'ItemContainerGenerator' accepting a first argument of type 'Telerik.Windows.Controls.RadGridView' could be found (are you missing a using directive or an assembly reference?) 

(I still use Q2
does it force me to upgrade now?)

Hello Orit,

With Q2 you can use ItemsControl.ItemsGenerator instead ItemContainerGenerator.

This is my code

 foreach (object item in RadGridView1.Items)
 {
       GridViewRow griParent = RadGridView1.ItemsControl.ItemsGenerator.ContainerFromItem(item) as GridViewRow;

the first rows are OK
but when it get the rows that are not in the screen
 the griParent  get null

Hi Orit,

I've attached small example to illustrate you how to achieve this using a bit different approach.

Thank You for the example
it looks fine
but there is one thing
I don't want to sellect all the rows at once
I have a "next" button
and in each click I want to move to the next result
so the

foreach (var item in items)
                   {
                       RadGridView1.SelectedItems.Add(item);
                   }

is not good for me
I need a way to select each time one row
something like
RadGridView1.SelectedItems.Add(item[index])

is there a way to do it?

[Orit]

I forgot a very important thing!
my grid is hierarchy
I notice that when I search the grid in this way

foreach (GridViewRowItem griParent in RadGridView1.ChildrenOfType<GridViewRowItem>())

 

it also get the children
but when I use

 

var

 

items = RadGridView1.Items.OfType<DataRowView>().Where(i => i.Row["ActivityName"].ToString().Contains(sSearch));
it doesnot get the children

Hello

I'm still waiting for your answer
do you have any idea for me?

Thanks

[Vlad]

Hello Orit,

This line:
var items = RadGridView1.Items.OfType<MyObject>().Where(i => i.Name.Contains(TextBox1.Text));

will get all items for this criteria however you can use other extension methods to get desired item. For example the first item will be:

var item = RadGridView1.Items.OfType<MyObject>().Where(i => i.Name.Contains(TextBox1.Text)).FirstOrDefault();

Generally ChildrenOfType will loop the visual tree elements recursively to find desired element type however Items is a flat collection of the items bound to the grid.
