Hi there.

I have followed the knowledgebase instructions to add a button in a column on my treeview and the nodes where the button should appear have changed in size but the button just does not appear. Help please

My company is the licence holder, I am the only developer.

Hello,

What is your company e-mail registered with us?
Please attach a sample project with your code to know how you add node controls and nodes. Also, what you need to accomplish in the treeview (clear goal)?

[davidacarter1984]

Code: [Select]

foreach (var orderline in orderlines)
                    {
                        Button viewButton = new Button();
                        OrderLineNode child = new OrderLineNode(order.Key.Ref + " " + orderline.Key.Dept);
                        child.Depot = orderline.Key.Dept;
                        child.PODSize = orderline.Key.size/1024;
                        child.PODscheck = (orderline.Key.POD != null);
                        child.Remainingcheck = (orderline.Key.POD == null);
                        child.Sentcheck = (orderline.Key.SendDate != "");
                        if (child.PODscheck)
                        {
                            pods++;
                           
                            viewButton.Text = "View";
                            child.Container = new ControlContainer(viewButton);
                            viewButton.Click += new EventHandler(viewButton_Click);
                        }
                       
                        if (child.Remainingcheck)
                        { rema++;  }
                       
                        if (child.Sentcheck)
                        { sent++;  }
                       
                       

                        child.AttachTo(node);
                       
                    }

Code: [Select]

public class OrderLineNode : NodeWithControl

    {
        public string Depot { get; set; }
        public bool PODscheck { get; set; }
        public bool Remainingcheck { get; set; }
        public bool Sentcheck { get; set; }
        public double? PODSize { get; set; }

        public OrderLineNode(string pText)
            : base (pText)
        {

        }
    }

Thank you. Also please post your tree`s design code (columns if any, etc.).

With all this code the button is appear correctly. The only problem here maybe in this code:

Code: [Select]

                        if (child.PODscheck)
                        {
                            pods++;
                           
                            viewButton.Text = "View";
                            child.Container = new ControlContainer(viewButton);
                            viewButton.Click += new EventHandler(viewButton_Click);
                        }
If child.PODscheck will be FALSE then the button won`t be added to the node and you wouldn`t see it.

[davidacarter1984]

in the ones where it it is true the node size increases as if to accomodate the button but i cannot see the button i have added a break point at the if statement and it runs the code inside it

[Ruslan]

Please attach the screen shot of the tree part where the button should be (scroll it to the last column with button).

[davidacarter1984]

screenshot attached

[Ruslan]

Please check the attached sample project that uses your design code and shows the button inside a column(see the attached screenshot).
Are you got the same result?

[davidacarter1984]

The button shows on this sample project, is there anything else which could be preventing it from being visible im using .net 4.0 full and flexibletreeview 3.3.1

[Ruslan]

The code in this sample is exactly from your messages except of adding many nodes from orderitems we add only one. Please compare it with your project, seems you didn`t send us exact code you are using. Or send us your project and we`ll find the problem.

[davidacarter1984]

Project attached i have made a few modifications since i sent the code to you and the data is drawn from a sql database.

[Ruslan]

Thank you for the sample project, we found what caused this behavior: if node isn`t attached to the treeview all his containers are not shown in the tree. The fix will be available in the next release.

To fix it in your project now, create child nodes and add them to the parent node only after attaching parent node to the treeview:

Code: [Select]

          if ((podRec.CheckState == CheckState.Indeterminate && podSent.Checked == node.Sentcheck) |
              (podRec.Checked == node.Remainingcheck && podSent.Checked == node.Sentcheck) |
              (podRec.CheckState == CheckState.Indeterminate && podSent.CheckState == CheckState.Indeterminate) |
              (podRec.Checked == node.Remainingcheck && podSent.CheckState == CheckState.Indeterminate))
          {
            node.AttachTo(flexibleTreeView1);

            // create and attach child node here!
          }
Actually you don`t need to create child nodes if parent node won`t be added to the tree.

[davidacarter1984]

looking at the way you structured the code wont that add the parent to the tree each time for however many child nodes there are
