Charts Programmatically

I have a used one of your chart demonstrations and require a little help.

DataTable table = PageAccess.CountOfEnquiriesBetweenDates(startDate, endDate);

var c = table.Rows.Count;

RadChart radChart = new RadChart();

radChart.ChartTitle.TextBlock.Text = "Enquiries";

radChart.Skin = "DeepGray";

var chartSeries = new ChartSeries {Name = "Enquiries", Type = ChartSeriesType.Bar};

//It works when I just put in a value

chartSeries.AddItem(c, "Enquiries");

from the code above I have executes a stored procedure retruned as a DataTable and I am then counting the number of rows in the table. I need this value to be in the graph data. I have tried Convert.ToDouble(c), I am using VS 2010. Can someone shed any light on what I have done wrong?

Many thanks

Simon

GridDropDownColumn & Binding to Non-foreign Key Columns

Hello,

Imagine two tables, each with two columns.

Operations

UserId

StartedBy

Users

Id

UserName

Operations.UserId is a FK to Users.Id. All columns are integers.

This works:

<telerik:GridDropDownColumn

DataField="UserId"

DataSourceID="UsersDataSource"

HeaderText="UserId"

ListTextField="UserName"

ListValueField="Id"

UniqueName="UserId">

</telerik:GridDropDownColumn>

This doesn't:

<telerik:GridDropDownColumn

DataField="StartedBy"

DataSourceID="UsersDataSource"

HeaderText="Started By"

ListTextField="UserName"

ListValueField="Id"

UniqueName="StartedBy">

</telerik:GridDropDownColumn>

Here's the DataSource:

<asp:EntityDataSource

ID="UsersDataSource"

runat="server"

ConnectionString="name=MyEntities"

DefaultContainerName="MyEntities"

EnableFlattening="False"

EntitySetName="Users"

EntityTypeFilter="User"

OrderBy="it.[UserName]">

</asp:EntityDataSource>

I know the UserId works because it is a foreign key but the second "StartedBy" is just a normal Int32 column in the Db that I have no control over (i.e. no relationship is or will be defined).

Normally, I'd just shrug and roll some code-behind but I'd much rather solve this in the declarative manner.

What is the simplest way I can get my StartedBy dropdown to bind via the value recorded in Operations.StartedBy?

AjaxManagerProxy and Content Areas

The latest controls build seems to break the old solution to the 100% height update panel issue (that of finding the update panel id server-side and setting its height explicitly cliient-side). This breakage is no big deal since I'd like to switch to using the relatively new UpdatePanelHeight property instead of the old hack. However, I have run into an issue. I have a MasterPAge and Contentpage and the latter has two Content Areas. Various controls in each Content are need to ajaxify eachother.

1) I'd like to place an AjaxManagerProxy declaration on the ContentPage so I can make use of the UpdatePanelHeight property, however, I'm not sure how to reference controls in the two contentAreas in the AjaxSettings.

2) OR, I can also set the ajaxSettings server-side, but then I don't know how to set the UpdatePanelHeight property.

Can someone let me know how to do either of these.. though #1 is preferrable.

P.S., it would be nice if you could extend the AddAjaxSetting Method to include a parameter for the UpdatePanelHeight.

Simple chart example

Hi,

Can anyone please help me with an example to bind a chart in the runtime using code behind?
I have stored procedures and .Net class files, with Datatable as output, ready with me.

I need a simple example to bind the chart with these classes' objects in the c# file.

Thanks...

radopen works differently after the first call

Simple situation.

In the web page:

<telerik:RadWindowManager ID="RWMan" runat="server">

<telerik:RadWindow ID="RWITaskView" runat="server" Width="400" Height="200" BorderColor="Blue"

DestroyOnClose="true" VisibleTitlebar="true" VisibleStatusbar="false"
NavigateUrl ="MemberITaskView.aspx"

VisibleOnPageLoad="false" AutoSize="true" AutoSizeBehaviors="Height, Width"
KeepInScreenBounds="false" Behaviors ="Close,Move"

EnableShadow="true" EnableEmbeddedSkins ="false">

</telerik:RadWindow >

<telerik:RadWindow ID="RWITaskEdit" runat="server" Width="400" Height ="200"

DestroyOnClose="true" VisibleTitlebar="true" VisibleStatusbar="false"
NavigateUrl ="MemberITaskEdit.aspx"

VisibleOnPageLoad="false" AutoSize="true" AutoSizeBehaviors="Height, Width"
KeepInScreenBounds="false" Behaviors ="Close,Move"

EnableShadow="true" EnableEmbeddedSkins ="false">

</telerik:RadWindow >

</Windows >

</telerik:RadWindowManager >

In databind event for a grid:

(e.Item.Cells[ViewPos].Controls[1]

as HyperLink).Attributes["onclick"] = "ShowITaskView('" + ky + "');" ;

In webpage script:

function ShowITaskView(id) {

var Wnd = radopen("MemberITaskView.aspx?itid=" + id, "RWITaskView" );

return false ;

}

PROBLEM:
1. On the first click on a hyperlink in the RadGrid control,
The autosize and everything works fine EXCEPT that the title bar and boundaries have opacity 0 somehow
2. On subsequent clicks on hyperlinks in same or other rows,
Autosize and everything does NOT work, AND the title bar and boundaries are normal.

See the two screen shots.

Any ideas?

Thanks.

Hierarchy grid - hide cells when expanded

Is there a way to define a hierarchy grid, but when I expand a particular row (too see its nested item) to hide all the cells in that row?

Something like here: http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/declarativerelations/defaultcs.aspx
But when the first row is expanded and I see the inner grid, I want to have the cells that contain: "ALFKI", "Maria Anders" and "Alfreds Futterkiste" hidden. And when I collapse the first row to have that cells displayed.

If there is no way to do that feel free to offer another solution.

Thanks,
Kamen

Export to pdf with DNN

I've got a radgrid in a dnn module/user control and I want to add exporting to pdf. The module is ajax enable via dnn and I'm pretty sure my problem is related to not doing a full postback. Nothing happens when you click the export to pdf button. I'm trying to register the export to pdf button to postback on the page load with no luck. For some reason I can't find the control.

Any help is appreciated, thanks.

protected void Page_Load(System.Object sender, System.EventArgs e)

{

RadGrid InventoryGrid = (RadGrid)InventoryRadGrid;

Control pdfExportButton = (Control)InventoryRadGrid.MasterTableView.FindControl("ExportToPdfButton");

if (pdfExportButton != null)

ScriptManager.GetCurrent(Page).RegisterPostBackControl(pdfExportButton);

else messageLabel.Text = "Export to PDF Control Not Found";

if (!IsPostBack)

{

}
