hey all. I am new in android programming. i tried to fill a listview with the datas that i pull from a Xml. I did almost everything and it works fine for now. But the images(320 X 230) in Listview can be seen in some devices(Samsung Galaxy Note 2 but imitation one) and in some devices cant be seen(Samsung Galaxy Note 3, HTC One M7, Samsung Galaxy S4) Can it be because of resolution problems or any other reason ?

i think i found the solution. The commented UIview animation block locked the main thread i think that is why Scroll View couldnt response to the new touches. but with this new animation block it works well.

- (void) scrollViewDidScroll:(UIScrollView *)scrollView
{

if (self.lastContentOffset > scrollView.contentOffset.y)
{
    if (self.altView.frame.size.height + self.altView.frame.origin.y > self.screenHeight)
    {

// [UIView animateWithDuration:0.5f animations:^{
// self.altView.frame = CGRectMake(0, self.altView.frame.origin.y-1, 320, 48);
// self.tarayici.frame = CGRectMake(0, self.tarayici.frame.origin.y, 320, self.tarayici.frame.size.height-1);
// }];

        \[UIView animateWithDuration:0.5f delay:0 options:UIViewAnimationOptionAllowUserInteraction animations:^{
            self.altView.frame = CGRectMake(0, self.altView.frame.origin.y-1, 320, 48);
            self.tarayici.frame = CGRectMake(0, self.tarayici.frame.origin.y, 320, self.tarayici.frame.size.height-1);
        } completion:^(BOOL finished) {
            
        }\];
    }
    
}
else if (self.lastContentOffset < scrollView.contentOffset.y)
{
    if (self.altView.frame.origin.y < self.screenHeight)
    {

// [UIView animateWithDuration:0.5f animations:^{
// self.altView.frame = CGRectMake(0, self.altView.frame.origin.y + 1, 320, 48);
// self.tarayici.frame = CGRectMake(0, self.tarayici.frame.origin.y, 320, self.tarayici.frame.size.height+1);
// }];
[UIView animateWithDuration:0.5f delay:0 options:UIViewAnimationOptionAllowUserInteraction animations:^{
self.altView.frame = CGRectMake(0, self.altView.frame.origin.y + 1, 320, 48);
self.tarayici.frame = CGRectMake(0, self.tarayici.frame.origin.y, 320, self.tarayici.frame.size.height+1);
} completion:^(BOOL finished) {

        }\];
    }
}

self.lastContentOffset = scrollView.contentOffset.y;

}

hey all. i have an UIWebView(tarayici in my situation) in view controller. it works fine when its scroll view delegate is not assigned to view controller. but i need to know when it is scrolled that is why i wrote this code.

self.tarayici.scrollView.delegate = self;

but when i write this down then webview acts so weird. for example after this code when i want to scroll then it scrolls only once if i make 3 or 4 attempts. so how can make it work more efficient with that code ?

public XmlNodeList XmlListesi()
{
XmlDocument doc = new XmlDocument();
doc.Load("http://cekilis.millipiyango.gov.tr/haftalik\_loto\_bilgileri.xml");
XmlElement root = doc.DocumentElement;
XmlNodeList elemlist = root.GetElementsByTagName("haftalik_loto_bilgileri");
return elemlist;
}

    public  DataTable ConvertXmlNodeListToDataTable(XmlNodeList xnl)
    {
        DataTable tablo = new DataTable();
        int TempColumn = 0;

        foreach (XmlNode item in xnl.Item(0).ChildNodes)
        {
            TempColumn++;
            DataColumn dc = new DataColumn(item.Name, System.Type.GetType("System.String"));
            if (tablo.Columns.Contains(item.Name))
                tablo.Columns.Add(dc.ColumnName = dc.ColumnName + TempColumn.ToString());
            else
                tablo.Columns.Add(dc);
        }

        int ColumnsCount = tablo.Columns.Count;
        for (int i = 0; i < xnl.Count; i++)
        {
            DataRow dr = tablo.NewRow();
            for (int j = 0; j < ColumnsCount; j++)
            {
                try
                {
                    dr\[j\] = xnl.Item(i).ChildNodes\[j\].InnerText;
                }
                catch (Exception)
                { }
            }
            tablo.Rows.Add(dr);
        }
        return tablo;
    }

    public  void  InsertSayisal(DataTable dt)
    {
        cmd = dal.InsertSayisal();
        cmd.Parameters.AddWithValue("@cek\_no", System.Data.SqlDbType.Int);

hi again.. thanks for help and your time..i solved my problem like below.in my button's click event that i create new row

int rowCount = datagridview1.Rows.Count;
DataGridViewButtonCell buttonCell = (DataGridViewButtonCell)datagridview1.Rows[rowCount].Cells[6];
buttonCell.UseColumnTextForButtonValue = false;
buttonCell.Value = "Insert";

vemedya.com

i couldnt find both events that u suggested...i have UserAddedRows and RowsAdded..i tried both

private void datagridview1_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e)
{
datagridview1.CurrentRow.Cells[6].Value = "Insert";
}

i cant catch Text Property here..that is why i used Value property but it gives error like "Object reference not set to an instance of an object." so what else i can try ?
