{
// Get the new page number
TextBox PageNumberTextBox = (TextBox)e.Item.FindControl("PageNumberTextBox");
int newPageNumber = -1;
try
{
newPageNumber = Convert.ToInt32(PageNumberTextBox.Text.Trim());
}
catch (FormatException)
{
Message.Text = "Invalid page number.";
return;
}
catch (OverflowException)
{
Message.Text = "Invalid page number.";
return;
}
int newIndex = (newPageNumber - 1) * e.Item.Pager.PageSize;
//Verify if the new index is valid
if (newIndex >= 0 && newIndex <= e.TotalRowCount)
{
//Set the new start index and maximum rows
e.NewStartRowIndex = newIndex;
e.NewMaximumRows = e.Item.Pager.MaximumRows;
}
else
Message.Text = "Invalid page number.";
}
Protected Sub TemplatePagerField_OnPagerCommand(ByVal sender As Object, _
ByVal e As DataPagerCommandEventArgs)
' Get the new page number
Dim PageNumberTextBox As TextBox = _
CType(e.Item.FindControl("PageNumberTextBox"), TextBox)
Dim newPageNumber As Integer = -1
Try
newPageNumber = Convert.ToInt32(PageNumberTextBox.Text.Trim())
Catch fex As FormatException
Message.Text = "Invalid page number."
Return
Catch oex As OverflowException
Message.Text = "Invalid page number."
Return
End Try
Dim newIndex As Integer = _
(newPageNumber - 1) * e.Item.Pager.PageSize
'Verify if the new index is valid
If newIndex >= 0 AndAlso newIndex <= e.TotalRowCount Then
'Set the new start index and maximum rows
e.NewStartRowIndex = newIndex
e.NewMaximumRows = e.Item.Pager.MaximumRows
