I try to follow the example in https://demos.telerik.com/aspnet-ajax/orgchart/examples/applicationscenarios/drilldowntoviewdetails/defaultvb.aspx?show-source=true but if I run the code and click on an icon for drill-down I get the error at the line "If e.SourceNode.ID <> "1" Then":
Telerik.Web.UI.OrgChartDrillDownEventArguments.SourceNode.get returned Nothing.
The code is:
If e.SourceNode.ID <> "1" Then
Dim item = New OrgChartGroupItem()
e.SourceNode.Renderer.Controls.Remove(e.SourceNode.Nodes.Renderer)
e.SourceNode.GroupItems.Clear()
e.SourceNode.Nodes.Clear()
e.SourceNode.GroupItems.Add(item)
End If
End Sub
Please advise!
Thx

I have a large dataset of employees.
I want to load one node initially and all other node collapsed and load other node on demand.
But this control is loading complete data on page load which is making it slow.
is there any way to rebind the org chart on expand and bind all child nodes?

My page logic is that I click on an 'Apply' button, then in the Apply_Click method, I do some data binding, such as: Grid1.Datasource = xxx; Grid1.DataBind(); . And the grid can show properly on the page. But when I click on other buttons on this page (for example: click the filter on the grid) to trigger a post back, the content on the grid just disappears (The datasource is stored in a session, so it's not datasource's problem). I need to add databind() to Page_Load() to prevent this from happening. But this is very weird and feels not right. Can you help me locate the real problem?
The same issue is happening bothe in Grid and OrgChart.

I read this , but when I copied the code into my own project and followed the documentation, this just didn't work. The node size and the group size are weird. No matter how I tried to edit the css settings, the height of the node just wouldn't change. Can anybody help me?
And btw I also want to ask, what do .rocItem and .rocItemContent mean? When I use my browser's inspect function, I also see a .rocItemTemplate, what is that?

So I have a organization chart and a button. When I click on the button, I will fill in a DataTable stored in ViewState to be the data source of the org chart. Since I'm still having the problem in another post that nobody replied yet: Databinding keeps disappearing when post back in UI for ASP.NET AJAX | Telerik Forums So I add some handling in Page_Load to avoid the org chart from becoming blank.
My Page logic is as follows:
<Telerik:RadButton ID="btn1" OnClick="btn_click">
...
<Telerik:RadOrgChart ID="OrgChart1">protected DataTable table1
{
get
{
if (ViewState["table1"] != null)
return (DataTable)ViewState["table1"];
else
return null;
}
set
{
ViewState["table1"] = value;
}
}
protected DataTable table2
{
get
{
if (ViewState["table2"] != null)
return (DataTable)ViewState["table2"];
else return null;
}
set
{
ViewState["table2"] = value;
}
}
protected void Page_Load(object sender, EventArgs e)
{
if (!PostBack) // do something
if (table1 != null && table2!=null) {
OrgChart1.GroupEnabledBinding.NodeBindingSettings.DataFieldID = "aaa";
OrgChart1.GroupEnabledBinding.NodeBindingSettings.DataFieldParentID = "bbb";
OrgChart1.GroupEnabledBinding.NodeBindingSettings.DataCollapsedField = "ccc";
OrgChart1.RenderedFields.NodeFields.Add(new OrgChartRenderedField() { DataField = "A" });
OrgChart1.GroupEnabledBinding.NodeBindingSettings.DataSource = table1;
OrgChart1.GroupEnabledBinding.GroupItemBindingSettings.DataFieldNodeID = "aaa";
OrgChart1.GroupEnabledBinding.GroupItemBindingSettings.DataFieldID = "ddd";
OrgChart1.GroupEnabledBinding.GroupItemBindingSettings.DataSource = table2;
OrgChart1.DataBind();
}
}
protected void btn_click(object sender, EventArgs e) {
// do something to provide data for table1 and table2
OrgChart1.GroupEnabledBinding.NodeBindingSettings.DataFieldID = "aaa";
OrgChart1.GroupEnabledBinding.NodeBindingSettings.DataFieldParentID = "bbb";
OrgChart1.GroupEnabledBinding.NodeBindingSettings.DataCollapsedField = "ccc";
OrgChart1.RenderedFields.NodeFields.Add(new OrgChartRenderedField() { DataField = "A" });
OrgChart1.GroupEnabledBinding.NodeBindingSettings.DataSource = table1;
OrgChart1.GroupEnabledBinding.GroupItemBindingSettings.DataFieldNodeID = "aaa";
OrgChart1.GroupEnabledBinding.GroupItemBindingSettings.DataFieldID = "ddd";
OrgChart1.GroupEnabledBinding.GroupItemBindingSettings.DataSource = table2;
OrgChart1.DataBind();
}
And then, when the page is post back, suddenly there are duplicate group names in the org chart as you can see in the screenshot.
Can somebody help me?

Is it possible to add a radbutton to org chart nodes? I would like to add a button to org chart nodes, and when the button is clicked, something happens to the webpage. I looked through demos and didn't find anything related? Could someone tell me if this is feasible? Thanks.

I am using the OrgChart control to display 1100 employees. Due to the size and structure of the company I have limited it to displaying 2 levels of employees and enabled drill down.
What I'm trying to implement now is the ability for someone to search for a particular employee and then jump to that location in the OrgChart. Is that even possible? If so, it certainly isn't straightforward.
Thanks,
Kyle
