Hi,

When I tried to expand my nodes in my RadTreeView I get the following error: 'The server method 'LoadNodes' failed'

I've placed a RadTreeView on a UserControl, in the Page_Init the UserControl is initialized.

Control control = LoadControl("/Pages/Controls/MenuControl.ascx");

control.ID = "menuControl";

panelMenu.Controls.Add(control);

Now the RadTreeView is defined as following:

<telerik:RadTreeView ID="radTOC" runat="server" Width="250px" Visible="false" CssClass="RadTreeView_RadSkins"

EnableEmbeddedSkins="False" ShowLineImages="false" Style="white-space: normal;">

<WebServiceSettings Path="../../Services/TreeViewService.asmx" Method="LoadNodes" />

</telerik:RadTreeView>

The treenodes are added to the RadTreeView as following:

foreach (Publication sub in subPublications)

{

RadTreeNode treeNode = new RadTreeNode(sub.Name, sub.PublicationID.ToString());

treeNode.ExpandMode = TreeNodeExpandMode.WebService;

radTOC.Nodes.Add(treeNode);

}

The webmethod in TreeViewService.asmx:

[System.Web.Script.Services.ScriptService]

public class TreeViewService : System.Web.Services.WebService

{

[WebMethod]

public static RadTreeNodeData[] LoadNodes(RadTreeNodeData node, object context)

{

List<RadTreeNodeData> result = new List<RadTreeNodeData>();

RadTreeNodeData nodeData = new RadTreeNodeData();

nodeData.Text = "Loaded on demand";

nodeData.ExpandMode = TreeNodeExpandMode.WebService;

result.Add(nodeData);

return result.ToArray();

}

Does anyone know what I'm doing wrong?

Regards,
Wouter splinter

multiple comboboxes in a datagrid

I wish to implement the functionality where we have multiple comboboxes with autocomplete functionality in a datagrid. The comboboxes will be added dynamically by the user as required. For example if they wish to select mutlple locations in a search they will type the location in the first combobox, then add another combobox to search for the second location.

We had an implmentation with the old asp.net version of the rad controls but it has broken in IE9. I was looking for something similar using the latest ASP.Net AJAX controls that would be IE9 compatible.

Stacked

I am trying to create a StackedBar chart but it seems to be rendering not as i would expect.

The chart is created programatically. I create a List<BindObj> (I have created a class 'BindObj') and then bind the chart to it.

BindObj:

public class BindObj

{

public string GroupColumnValue { get; set; }

public string XColumnValue { get; set; }

public decimal YColumnValue { get; set; }

}

To create and bind the chart:

IList<BindObj> datasource = new

List<BindObj>();

BindObj bindingObj1 = new BindObj();

bindingObj1.XColumnValue = "11/04/2011";

bindingObj1.YColumnValue = 1;

bindingObj1.GroupColumnValue = "11/04/2011"

BindObj bindingObj2 = new BindObj();

bindingObj2.XColumnValue = "11/04/2011";

bindingObj2.YColumnValue = 1;

bindingObj2.GroupColumnValue = "11/04/2011"

BindObj bindingObj3 = new BindObj();

bindingObj3.XColumnValue = "11/04/2011";

bindingObj3.YColumnValue = 1;

bindingObj3.GroupColumnValue = "11/04/2011"

BindObj bindingObj4 = new BindObj();

bindingObj4.XColumnValue = "13/04/2011";

bindingObj4.YColumnValue = 1;

bindingObj4.GroupColumnValue = "13/04/2011"

BindObj bindingObj5 = new BindObj();

bindingObj5.XColumnValue = "14/04/2011";

bindingObj5.YColumnValue = 1;

bindingObj5.GroupColumnValue = "14/04/2011"

BindObj bindingObj6 = new BindObj();

bindingObj6.XColumnValue = "14/04/2011";

bindingObj6.YColumnValue = 2;

bindingObj6.GroupColumnValue = "14/04/2011"

datasource.Add(bindingObj1);

datasource.Add(bindingObj2);

datasource.Add(bindingObj3);

datasource.Add(bindingObj4);

datasource.Add(bindingObj5);

datasource.Add(bindingObj6);

RadChart testChart = new RadChart();

testChart.DefaultType = Telerik.Charting.ChartSeriesType.StackedBar;

testChart.PlotArea.XAxis.DataLabelsColumn = "XColumnValue";

testChart.DataGroupColumn = "GroupColumnValue";

testChart.DataSource = datasource;

testChart.DataBind();

I would have expected:
    _________                ________
    |                |                |                |
    | bindobj3 |                |                 |
    |________|                | bindobj6 |
    |                |                |                |
    | bindobj2 |                |                |
    |________|________|________|
    |                |                |                |
    | bindobj1 | bindobj4 |  bindobj5 |
    |________|________|________|
     11/04/11   13/04/11   14/04/11

All the items with an X Value of 11/04/11 in the first column, all the items with an X Value of 13/04/11 in the second and finally all the items with an X Value of 14/04/11 in the final column.

Instead I get:

    _________________
    |                |                |
    | bindobj5 |                |
    |________| bindobj6 |
    |                |                |
    | bindobj4 |                |
    |________|________|________
    |                |                |                |
    | bindobj1 | bindobj2 |  bindobj3 |
    |________|________|________|
     11/04/11   13/04/11   14/04/11

I tried to attatch a sample project, but cant seem to attatch a zip file. Dropping the above code into a standard aspx page should illustrate what I am trying to say.

Maybe I am just not thinking about this correctly?! Can anyone shed any light on how I would get the result I want?

Thanks,

Add dynamic button and checkbox to tooltip

I'm trying to generate content on a tooltip dynamically from a database. The problem is, I need to add dynamic check boxes. I looked through the demos but didn't see anything like this. I get an error when I try to add the checkbox, but I put it in to show what I need to do. I couldn't get the button to add either. Do you have any ideas? Here's the vb. The aspx for the tooltip is just standard stuff.

callBack.Text = "<div style=""margin-left: 10px; margin-top: 10px;""><b>Call Backs</b><br /><table cellpadding=""5"">"

callBack.Text &= "<tr><td>Customer:</td><td>Phone:</td><td>Call Back Date:</tr>"

Dim check As CheckBox

While reader.Read()

check = New CheckBox

check.ID = reader(4)

check.Text = "Called Back"

If (reader(3).ToString <> "") Then

callBack.Text &= "<tr><td style=""width: 170px"">" & reader(2) & " - " & reader(3) & "</td><td>" & reader(1) & "</td><td>" & reader(0) & "</td><td>" & callBack.Controls.Add(check) & "</tr>"

Else

callBack.Text &= "<tr><td style=""width: 170px"">" & reader(2) & "</td><td>" & reader(1) & "</td><td>" & reader(0) & "</tr>"

End If 'if reader(3)

End While

Dim btn As Button = New Button

btn.ID = "updateCall"

btn.Text = "Update"

callBack.Controls.Add(btn)

AddHandler btn.Click, AddressOf buttonClick

callBack.Text &= "</table><br /></div>"

callBack.Show()

Different templates

Hi,

I'm developing a google-like search webpage and I wonder how to achieve the same presentation. I mean that some items have different layouts. If you look at google webpage, images/videos/news items have different layouts. Can we achieve this using RadListView? (it would mean loading templates dynamically for each item) or maybe using other controls... ?

Accessibility Support

Hello All,

I am currently performing DDA I have a question regarding the Telerik ASP.NET controls and accessibility support.

Accessibility support for these controls is documented here - http://www.telerik.com/products/aspnet-ajax/getting-started/accessibility-support.aspx. It states that the Telerik Grid has a W3C compliance level of "AA".

If you read the W3C WCAC guildelines available here - http://www.w3.org/TR/WCAG10-HTML-TECHS/#identifying-table-rows-columns, you will notice that the example code for identifying row and column information includes "<CAPTION>" and "headers" tags as part of the priority 1 ("A") compliance. I have checked the Telerik Grid (available here - http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/accessibility/defaultcs.aspx) and it does not appear to generate this information.

My question is, how is the Telerik Grid "AA" W3C complaint without implementing this functionality?

Many thanks in advance for any information you may have.

Regards,

Aaron
