+# How to change the PageCount at runtime when data loaded on demand is filtered in winforms datapager
+
+This example illustrates how to change the `PageCount` at runtime when data loaded on demand is filtered in [WinForms DataPager](https://help.syncfusion.com/cr/windowsforms/Syncfusion.WinForms.DataPager.SfDataPager.html).
+
+You can change the [SfDataPager.PageCount](https://help.syncfusion.com/cr/windowsforms/Syncfusion.WinForms.DataPager.SfDataPager.html#Syncfusion_WinForms_DataPager_SfDataPager_PageCount) at runtime based on the records count in on-demand paging. Here, `PageCount` are modified by filtering the records in run time.
+
+```c#
+public partial class Form1 : Form
+{
+    Northwind northWind;
+    List<Orders> source = new List<Orders>();
+
+    public Form1()
+    {
+        InitializeComponent();
+        string connectionString = string.Format(@"Data Source = {0}", ("Northwind.sdf"));
+        //northWind dataProvider connectivity.
+        northWind = new Northwind(connectionString);
+        source = northWind.Orders.ToList();
+        this.sfDataPager1.OnDemandLoading += OnDemandLoading;
+    }
+
+    private void OnDemandLoading(object sender, OnDemandLoadingEventArgs e)
+    { 
+        sfDataPager1.LoadDynamicData(e.StartRowIndex, source.Skip(e.StartRowIndex).Take(e.PageSize));
+    }
+
+    private List<Orders> ApplyFilter(Northwind NorthwindSource)
+    {
+        // records are filtered based on CustomerID column
+        return NorthwindSource.Orders.Where(item => item.CustomerID.Contains(filterTextBox.Text)).ToList();
+    }
+
+    private void FilterBtn_Click(object sender, System.EventArgs e)
+    {
+        source = ApplyFilter(northWind);
+        //page count resets based on filtered records.
+        if (source.Count() < sfDataPager1.PageSize)
+            this.sfDataPager1.PageCount = 1;
+        else
+        {
+            var count = source.Count() / sfDataPager1.PageSize;
+            if (source.Count() % sfDataPager1.PageSize == 0)
+                this.sfDataPager1.PageCount = count;
+            else
+                this.sfDataPager1.PageCount = count + 1;
+        }
+        this.sfDataPager1.MoveToPage(0);
+        this.sfDataPager1.Refresh();
+    }
