repeater ItemDataBound:
protected void Repeater_sorular_ItemBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
int SurveyId = Int32.Parse(Request.QueryString["anket_id"]);
var sorular = from sr in db.TableSurveyQuestions
where sr.SurveyId == SurveyId
select sr;
//int repeater_satir = 0;
foreach (var soru in sorular)
{
RadChart RadChart1 = new RadChart();
RadChart1 = (RadChart)e.Item.FindControl("RadChart1");
ChartSeries s = RadChart1.Series.GetSeries(0);
s.Appearance.LegendDisplayMode = ChartSeriesLegendDisplayMode.ItemLabels;
s.Clear();
s.Appearance.ShowLabels = true;
s.Appearance.LabelAppearance.Dimensions.Margins.Bottom = 7;
s.PlotArea.IntelligentLabelsEnabled = true;
s.DataYColumn = "VoteCount";
int oy_sayisi = 0;
foreach (var secenek in soru.TableSurveyOptions)
{
int toplam_cevap_sayisi = secenek.TableSurveyVotes.Count;
int dogru_cevap_sayisi = secenek.TableSurveyVotes.Where(a => a.VoteStatus == true).Count();
double yuzde = ((double)dogru_cevap_sayisi / (double)toplam_cevap_sayisi) * 100;
ChartSeriesItem seriesItem = new ChartSeriesItem();
seriesItem.YValue = Math.Round(yuzde, 2);
seriesItem.Name = secenek.OptionName;
seriesItem.ActiveRegion.Tooltip = secenek.OptionName;
seriesItem.Label.TextBlock.Text = secenek.OptionName + " %" + Math.Round(yuzde, 2).ToString();
seriesItem.Appearance.Border.Color = Color.Silver;
seriesItem.Appearance.FillStyle.FillType = Telerik.Charting.Styles.FillType.Solid;
s.Items.Add(seriesItem);
RadChart1.Series.Add(s);
oy_sayisi = secenek.TableSurveyVotes.Count;
}
RadChart1.ChartTitle.TextBlock.Text = db.TableSurveyQuestions.Where(a => a.SurveyId == SurveyId).FirstOrDefault().TableSurvey.Title;
RadChart1.Legend.TextBlock.Text = "Toplam : " + oy_sayisi + " Oy ";
//repeater_satir++;
}
}
}
when I write this code, all charts are showing the last object values. I want to set each chart with different data.
How can I do this.
Thanks.

You could use the ItemIndex property
<asp:Repeater runat="server" ID="myRepeater" OnItemDataBound="myRepeater_ItemDataBound">
<ItemTemplate>
<asp:Label Text='<%# Eval("Id") %>' runat="server" ID="myRepeaterLabel" />
</ItemTemplate>
</asp:Repeater>
Code behind:
protected void myRepeater_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
switch (e.Item.ItemIndex)
{
case 3:
Label l = (Label)e.Item.FindControl("myRepeaterLabel");
l.Text += "whatever";
break;
default:
break;
}
}
}
Output:
Edited
I am not sure if this would help but you should bind your repeater like this:
protected void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)
{
this.BindRepeater();
}
}
private void BindRepeater()
{
var r = Builder<Product>.CreateListOfSize(20).Build();
this.myRepeater.DataSource = r;
this.myRepeater.DataBind();
}
And just modify specific values already bindded in the ItemDataBound event
