I have a window project in which I had to show specific number of records and that that
specific number of records will display
in each next and previous button . I have used list<> for the
datasource For Datagridview.
int skip = 0, take = 0, nextCount=0;
private void
StoreRoomBM_Load(object sender, EventArgs e)
{
FillAllLoadTime();
}
void FillAllLoadTime()
{
var a = from p in lstDetails.Take(5)
select p;
if (a.ToList().Count > 0)
{
int showtotal = a.ToList().Count;
DataDetailsData.DataSource = a.ToList();
LblREcordCount.Text = 1 + " - "
+ showtotal + " of " + lstDetails.Count;
btnPrevious.Enabled = false;
LblRecord.Visible = false;
}
else
{
DataDetailsData.DataSource = null;
LblRecord.Visible = true;
}
}
private void
btnNext_Click(object sender, EventArgs e)
{
try
{
nextCount ++;
for (int
i = 1; i < LstDetails.ToList().Count/5 + 1
; i++)
{
if (nextCount == i)
{
skip = skip + 5;
take = 5;
var a = from p in LstDetails.Skip(skip).Take(take)
select p;
if (a.ToList().Count > 0)
{
btnPrevious.Enabled
= true;
DataDetailsData.DataSource = a.ToList();
LblREcordCount.Text
= (skip + 1) + " - " + (skip + take)
+ " of
" + LstDetails.Count;
LblRecord.Visible =
false;
}
else
{
DataDetailsData.DataSource = null;
LblRecord.Visible =
true;
}
}
}
}
catch (Exception
ex)
{
}
}
private void
btnPrevious_Click(object sender, EventArgs e)
{
try
{
nextCount--;
for (int
i = 0; i < LstDetails.ToList().Count / 5
; i++)
{
if (nextCount == i)
{
skip = skip - 5;
take = 5;
var a = from p in LstDetails.Skip(skip).Take(take)
select p;
if (a.ToList().Count > 0)
{
DataDetailsData.DataSource = a.ToList();
LblREcordCount.Text
= (skip + 1) + " - " + (skip +
take) + "
of " + LstDetails.Count;
LblRecord.Visible =
