Thanks, that is the example that I am following, but I don't want to change pages. I want to change the number of records per page by Drop down list.

Thanks

Grrr.  Ya, my bad.  I realized I didn't really answer your question about 5 seconds after I hit the send button, but the forums had apparently already sent the email.  Sorry for the confusion.

I am working on a sample to answer your real question...

I have figured this out, but I am still trying to get it to hit the correct row, based on where you started.  I have no idea if this is the most efficient, but it is working.

First I had to define some variables in the code behind, and I had to add this line to the loadeddata event..  Without this line it kept going back to page 1.

customerXamGrid.PagerSettings.CurrentPageIndex = newPage;

I also want to add another line here to set the current row to newLine, but I cannot figure out how to set the current line on the grid.    grid.activecell.row.index is read only.

newPage is set at 0 when the page is loaded.

Then I have a textbox with the lines per page.  I am currently setting it to 20 as a default, as well as using that constant in the xaml.

This is the event when the user changes the value in that textbox.

 

 

 

 

 

 

 

 

 

 

 

 

private void rpp_ValueChanged(object sender, RoutedEventArgs e)

{

 

if (rpp.Text != null & customerDomainDataSource.CanLoad & rpp.Text.Length==2)

//can load makes sure we don't have unsaved changes

{

 

int rppvalue = int.Parse(rpp.Text);

 

 

 

if (rppvalue != customerDomainDataSource.PageSize & rppvalue >9 & rppvalue<50 )

{

 

int rownum;

 

 

 

try { rownum = customerXamGrid.ActiveCell.Row.Index; }

// null if no activecell, so use first row

 

 

 

catch { rownum = 0; }

 

 

 

int curpos = customerXamGrid.PagerSettings.CurrentPageIndex * customerXamGrid.PagerSettings.PageSize + rownum;

// curpos is the row in the entire dataset

customerDomainDataSource.LoadSize = customerDomainDataSource.PageSize = customerXamGrid.PagerSettings.PageSize  = rppvalue;

 

 

newPage = (int)decimal.Truncate(curpos / rppvalue);

newLine = curpos - customerDomainDataSource.PageSize * newPage;

}}}

Thanks for reply, Stevez.

But binding on Cell.Row.ColumnLayout.PagerSettings.PageSizeResolved or Cell.Row.ColumnLayout.Grid.PagerSettings.PageSize

is works only one time, when table loading, TwoWay binding is not working, so when i change value on face, no changes on XamGrid's PagerSize.

Have you ideas how i can solve that problem: i can use Loaded event on TextBox that binds to PageSize and set PageSize manually, but i have 2 tables whith one PagerCellControlTemplate?

Hi, 

So to get the PageSize, you want to bind to:
Cell.Row.ColumnLayout.PagerSettings.PageSizeResolved
or
Cell.Row.ColumnLayout.Grid.PagerSettings.PageSize. 

The PagerSettings on the ColumnLayout defaults to 0 unless specified directly.

As for showing the filtered row count via a binding, i'm actually not sure about that one. The Collection does actually have the right count, the issue is that Count doesn't raise a PropertyChanged event, which is why it'll show a stale value.

Hi,Devin! Thanks for you sample. I add a TextBox to the PagerCellControl template, like this: [TextBox Text="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Cell.Row.ColumnLayout.PagerSettings.PageSize,Mode=TwoWay}" /] When i put value to TextBox, PageSize is changing, but at first time, when page just loaded, value on TextBox is always 0. And i have another question: What property should bind if i want get count of records after filtering, that contains in XamGrid? Another, how i can get count of filtered records? I tried: [TextBox Text="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Cell.Row.Manager.Rows.ActualCollection.Count,Mode=TwoWay}" /] But it return all records in grid. Thanks. p.s. sorry for my pure english
