I use telerik pie chart and I create it on server (from DB):

        private void cViolationsPerTime_NeedDataSource(object sender, EventArgs e)
        {
            Telerik.Reporting.Processing.Chart procChart = (Telerik.Reporting.Processing.Chart)sender;

            procChart.DataSource = BLL.BO.Audit.ExecuteAuditCommand(GenerateViolationsPerTimeSql(filters, "All"), type, conn, fromDate, toDate);

            Telerik.Reporting.Charting.ChartSeries csViolationsPerTime = new Telerik.Reporting.Charting.ChartSeries();
            csViolationsPerTime.DataYColumn = "NumOfViolations";
            csViolationsPerTime.Type = Telerik.Reporting.Charting.ChartSeriesType.Pie;
            csViolationsPerTime.DataLabelsColumn = "timeslot";

            csViolationsPerTime.Appearance.LegendDisplayMode = Telerik.Reporting.Charting.ChartSeriesLegendDisplayMode.ItemLabels;
            csViolationsPerTime.Appearance.ShowLabelConnectors = true;
            csViolationsPerTime.Appearance.TextAppearance.TextProperties.Font = new System.Drawing.Font("Calibri", 7F);

            cViolationsPerTime.Series.Clear();
            cViolationsPerTime.Series.Add(csViolationsPerTime);

        }


Attached screen shot with the result I get.
I want to get different legend then the data labels.
How can I bind a different column to the legend?

This is my SQL result:
timeslot     numOfViolations
10:00-12:00      40
12:00-14:00      10
14:00-16:00      8

etc...

I want each part of the pie to display the number of violations, and in legend I want to see the time slot.       

I have a rad splitter, inside that i have two RadPanes named as "rLeftPane" and "rContentPane".

In "rLeftPane" RadPane (ie. LEFT RadPane) I am loading an ASP.NET usercontrol which behaves as a menu, the usercontrol basically, is nothing but a RadWindow.

Now inside the "rContentPane" RadPane(ie. RIGHT RadPane) I am having another RadWindow named as "rwMain", which is used to load the aspx pages (combination of master page and content page), which is loaded in AJAX call and does not postback's the page.

Now what I want is, this, staying inside the "rContentPane" RadPane's (ie. RIGHT RadPane) RadWindow, at page loading, I want to access a control's present inside RadWindow which is in "rLeftPane" RadPane(ie. LEFT RadPane).

Here is the code :

<telerik:RadSplitter ID="Splitter" runat="server" Width="100%" Height="100%" VisibleDuringInit="false"
            Skin="Office2007" OnClientResizing="Resizing">

            <telerik:RadPane ID="rLeftPane" runat="server" Width="200" MinWidth="200" MaxWidth="200"
                OnClientCollapsed="WindowShow" OnClientExpanded="WindowShow" BackColor="DarkGray">

                <ERPx:LeftMainMenu ID="ucLeftMainMenu" runat="server" /> // This is my UserControl

            </telerik:RadPane>

            <telerik:RadSplitBar ID="VerticalSplitBar" runat="server" CollapseMode="Forward" EnableResize="false" />

            <telerik:RadPane ID="rContentPane" runat="server">

                <telerik:RadWindow ID="rwMain" runat="server" VisibleOnPageLoad="true" ShowContentDuringLoad="false"
                    OnClientShow="WindowShow" VisibleStatusbar="False" Behaviors="None" EnableShadow="false" OnClientBeforeClose="OnClientBeforeClose1" OnClientPageLoad="WindowLoad" IconUrl="images/18_users.gif" Skin="Office2007">
                </telerik:RadWindow>

            </telerik:RadPane>
        </telerik:RadSplitter>

Please help me out.

Thanks.

Hi All,

I'm using telerik 2013 Q3 for development. Now I want to implement a page that contains a radgrid, and the radgrid can expand to expand a DetailTables. The DetailTables has just one column GridTemplateColumn and in its ItemTemplate contains a RadTreeList.
My question is after click expand button, I cannot get RadTreeList instance whatever from dataBound, ItemCreated or anyother events. So how can I set datasource to the RadTreeList in DetailTables ItemTemplate.

Can anyone help on this, please? Thanks.

ello I've got some problem wih the paging of Telerik RadGrid Control! When it's first page - there is no problem it loads me three rows as I have givenpageSize property value - "3". But when I try to get to the second page - it gives me an error:



Here is my aspx file

<
And here is my cs File with only one function in which I get the data for datasource from a web service and bind it to the radGrid:

All,

I have table which is build in .net, dynamically (server side), which shows me an overview of all people that need to work on a specific day for a specific area.

A list is fine, but I would like to visualize this for users. I have multiple working area's and up to 20 people working per working area per day, so putting it all into an outlook style calender overview is useless as it will become to complicated.

I now had the idea to add a HR per entry (tr) which would correspond to the hours they need to work. (some like a range bar)

Attached the screenshot where i added the green lines in paint, to show what i'm trying to achieve. (The table is in Dutch but you can easily see what the working hours are)

Is there any telerik control that would offer this functionality?

Hi,
In one of a form in our application we have a rad combo which updates itself with data everytime we change some parameters in form. We are using a webservice to get the list of  RadComboItemData and bind on the client side.

When we bind whats happening is that the last selected text still remains visible even if its not in the new list. We have a required field validator for the list. If I manually do select on the first item (First item displays a message that an item must be selected) of the new list using comboItem.Select() it launches validation and dispalys our required field validator that an item must be selected.
 
Is there a proper way of doing it so that new list populates itself without any garbage left over from the last binded data?

My second question is can we do validation on value of the selected item instead of text?

Thanks in advance for your help.

Best regards,
Khurram

Client side binding function

function bindCombo(combo,result){

var items = combo.get_items();

items.clear();

for(var i=0;i< result.length;i++){

var comboItem = new Telerik.Web.UI.RadComboBoxItem();

comboItem.set_text(result[i].Text);

comboItem.set_value(result[i].Value);

items.add(comboItem);

if (i == 0) {

comboItem.select();

}

}

}

 

When you select a file to upload first attach only one photo-Loading and the progress is not displayed. So when you select the file, close the window and back to the normal upload. If you select a file, then upload again reloading the phenomenon of the show will be repeated only. I would like to know why it does this??

Hi
I'm trying to drop a listbox row into a full grid.
The grid have 10 row and there is no extra space into the grid where dropped my listbox row. I thought the event had to be fired even if I dropped the row on a grid row but nothing happens.

Thanks
