RadGridView Total Rows Count

I need to get the total number of rows contained in a RadGridView. The Rows.Count property of the RadGridView only returns the number of rows on the current page.


The only way to get the total rows count is by calculating the number of rows per page and adding them to the running total.

The following code demonstrates how to get the rows count of the RadGridView shown on this Telerik demo site. We use a Do/While loop in code which exits once the "Next Page" button is no longer Enabled. Then the row count is performed once more to account for the last page.

int extentHeight; // The total height of the grid, visible plus non-visible 
int rowHeight; // The height of the row 
// Copy the RadGridView into a local variable as a shortcut 
RadGridView grid = Pages.TelerikGridViewFor2.SilverlightApp.GridViewRadgridview; 
// Grab the VirtualizingPanel contained in the RadGridView. This is used to control the viewable portion of the grid. 
FrameworkElement VirtualizingPanel = grid.Find.ByType("GridViewVirtualizingPanel"); 
// Detect the extent height and the row height 
extentHeight = (int)VirtualizingPanel.GetProperty(new AutomationProperty("ExtentHeight", typeof(int))); 
rowHeight = (int)grid.GetProperty(new AutomationProperty("RowHeight", typeof(int))); 
int totalPageRows = 0;     
int totalOverallRows = 0; 
// Calculate the total overall rows until the "Next Page" is no longer Enabled  
totalPageRows = (extentHeight/rowHeight); 
totalOverallRows = totalPageRows + totalOverallRows; 
totalPageRows = (extentHeight/rowHeight); 
totalOverallRows = totalPageRows + totalOverallRows; 
// Show the result 
Log.WriteLine("Total Number of Rows: "+ totalOverallRows.ToString()); 
Dim extentHeight As Integer 
Dim rowHeight As Integer 
Dim grid As RadGridView = Pages.TelerikGridViewFor2.SilverlightApp.GridViewRadgridview 
Dim VirtualizingPanel As FrameworkElement = grid.Find.ByType("GridViewVirtualizingPanel") 
extentHeight = CInt(VirtualizingPanel.GetProperty(New AutomationProperty("ExtentHeight", GetType(Integer)))) 
rowHeight = CInt(grid.GetProperty(New AutomationProperty("RowHeight", GetType(Integer)))) 
Dim totalPageRows As Integer = 0 
Dim totalOverallRows As Integer = 0 
    totalPageRows = (extentHeight / rowHeight) 
    totalOverallRows = totalPageRows + totalOverallRows 
Loop While Pages.TelerikGridViewFor2.SilverlightApp.MoveToNextPageButtonRadbutton.IsEnabled 
totalPageRows = (extentHeight / rowHeight) 
totalOverallRows = totalPageRows + totalOverallRows 
Log.WriteLine("Total Number of Rows: " + totalOverallRows.ToString())
