Treeview

[Marcia Marino]

Is there a sample how to use the treeview on SharePoint 2003?

[Dimitar Milushev]

Hi Marcia,

You need to create a custom WebPart that includes an instance of the treeview and populates it. Here are two links that should get you started with the WebPart creation - http://msdn.microsoft.com/office/default.aspx?pull=/library/en-us/dnofftalk/html/office07012004.asp and http://www.devx.com/dotnet/Article/17518/0/page/1

As far as the r.a.d.treeview code is concerned, you can have a look at the online examples www.telerik.com/r.a.d.treeview.
For a start, you should override the CreateChildControls method of the WebPart. Inside the method, create and populate the treeview. Here is a simple example that creates a treeview with one parent node and one child node:

protected override void CreateChildControls()
{
    RadTreeView treeView = new RadTreeView();

    treeView.ID = "radTreeView";

    RadTreeNode parentNode = new RadTreeNode();
    parentNode.Text = "Parent";

    treeView.Nodes.Add(parentNode);

    RadTreeNode childNode = new RadTreeNode();
    childNode.Text = "Child";

    parentNode.Nodes(Add(childNode);

    Controls.Add(treeView);
    base.CreateChildControls();
}

I should mention that we will be releasing navigation WebParts for SharePoint soon, including one using r.a.d.treeview. If you want to replace the default SharePoint navigation, the new WebParts should prove very helpful.

Thanks, has anyone try to query the document library. I'm having problems.

[Marcia Marino]

Ok I can query sharepoint, but I'm get a permission error from share point. I have coment all my code and now I'm just declaring the tree and still getting same error.

// }

 

// protected OrgMenu.LMCreateChildControls lmtreenav;

protected override void CreateChildControls()

{

 

RadTreeView treeView = new RadTreeView();

 

this.Controls.Add(treeView);

base.CreateChildControls();

}

//

/// <summary>

/// Render this Web Part to the output parameter specified.

/// </summary>

/// <param name="output"> The HTML writer to write out to </param>

protected override void RenderWebPart(HtmlTextWriter output)

{

this.EnsureChildControls();

this.RenderControl(output);

}

 

}

}

I Have add RadControls to Virtual Directory, DLL is on BIN folder.
What Am I missing?

Would be better to call it from ASCX control?

Thanks

Hi Marcia,

Try setting the trust level to full. To do this, open Sharepoint's web.config file (usually found in c:\inetpub\wwwroot) and set the level attribute of the <trust> tag to "Full" like this:

<trust level="Full" originUrl="" />

Also make sure there is an entry for your WebPart in the <SafeControls> in web.config.

All the best,

I forgot to mention that I'm not using the Portal just the Services, would that make difference.

 

Thanks

Hello Marcia,

Did you try just adding the treeview in the GAC? This should help since adding an assembly to the GAC basically equals Full trust for that assembly.

Also do not forget to do an iisreset after you modify the trust level for the SharePoint site.

OK my bos does not want me to add the tree to GAC, I was able to run the given sample I receive here, by creating a Custom config file, now that I'm trying to query Share point I get the following error.

Hi Marcia,

As stated in the exception r.a.d.treeview requires its ID property to be explicitly set. Please set it to some value e.g. "treeView" and everything should work as expected.

protected override void CreateChildControls()
{
  RadTreeView treeView = new RadTreeView();
  treeView.ID = "treeView";
  this.Controls.Add(treeView);
  base.CreateChildControls();
}

I was able to create the part on development and have been working fine, now I deployed to production an I get a error message "RadTreeView" is undefined, it get filled it does not display the images or the tree fomat for that matter.

[Atanas Korchev]

Hello Marcia,

You have probably not set up your production environment like your development one. The "RadTreeView is undefined" error is likely to happen if you have not copied the RadControls folder right or you have not excluded it from SharePoint managed paths using stsadm.exe -addpath. Please make sure the changes made to your dev environment are applied to your production server.

[Marcia Marino]

Yes I did, create the folder under the web root, create the virtual directory, change on the config file, place the DLL on the bin folder.

Restarted IIS.

[Marcia Marino]

Thanks that work, well I'm live know.
