Problem with the selected node to group / ungroup

Hi;

I have a problem when I want a selected node and Group / Ungroup the tree holding the selected node. Here's an example to understand the case:

public Form1()

{

InitializeComponent();

DataTable table = new DataTable();

table.Columns.Add("ID", typeof(int));

table.Columns.Add("ID_PADRE", typeof(int));

table.Columns.Add("Codigo", typeof(string));

table.Columns.Add("TEXTO_NODO", typeof(string));

table.Columns.Add("TIPO", typeof(string));

table.Rows.Add(1, null, "COD 1", "Descripción 1","C");

table.Rows.Add(2, null, "COD 2", "Descripción 2","E");

table.Rows.Add(3, null, "COD 3", "Descripción 3", "A");

table.Rows.Add(4, null, "COD 4", "Descripción 4", "S");

table.Rows.Add(5, null, "COD 5", "Descripción 5", "R");

table.Rows.Add(6, 1, "COD 6", "Descripción 6","S");

table.Rows.Add(7, 2, "COD 7", "Descripción 7","R");

table.Rows.Add(8, 3, "COD 8", "Descripción 8","R");

table.Rows.Add(9, 4, "COD 9", "Descripción 9","S");

table.Rows.Add(10, 5, "COD 10", "Descripción 10","C");

table.Rows.Add(11, 1, "COD 11", "Descripción 11","R");

table.Rows.Add(12, 2, "COD 12", "Descripción 12","S");

table.Rows.Add(13, 3, "COD 13", "Descripción 13","A");

table.Rows.Add(14, 4, "COD 14", "Descripción 14","E");

table.Rows.Add(15, 5, "COD 15", "Descripción 15","R");

table.Rows.Add(16, 6, "COD 16", "Descripción 16","S");

table.Rows.Add(17, 7, "COD 17", "Descripción 17","E");

table.Rows.Add(18, 8, "COD 18", "Descripción 18","R");

table.Rows.Add(19, 9, "COD 19", "Descripción 19","C");

table.Rows.Add(20, 10, "COD 20", "Descripción 20","A");

table.Rows.Add(21, 20, "COD 21", "Descripción 21","S");

this.radTreeView1.DataSource = table;

this.radTreeView1.DisplayMember = "TEXTO_NODO";

this.radTreeView1.ChildMember = "ID";

this.radTreeView1.ParentMember = "ID_PADRE";

this.radTreeView1.ExpandAll();

this.radGridView1.Relations.AddSelfReference(this.radGridView1.MasterTemplate, "ID_PADRE", "ID");

this.radGridView1.DataSource = table;

}

private void ungroup()

{

RadTreeNode oNode = this.radTreeView1.SelectedNode;

this.radTreeView1.ChildMember = "";

this.radTreeView1.ParentMember = "";

this.radTreeView1.SelectedNode = oNode;

}

private void group()

{

RadTreeNode oNode = this.radTreeView1.SelectedNode;

this.radTreeView1.ChildMember = "ID";

this.radTreeView1.ParentMember = "ID_PADRE";

this.radTreeView1.ExpandAll();

this.radTreeView1.SelectedNode = oNode;

}

private void label1_Click(object sender, EventArgs e)

{

this.ungroup();

}

private void label2_Click(object sender, EventArgs e)

{

this.group();

}

If I have a selected node when calling the method to group / ungroup not maintained after I selected group / ungroup. I tried with what appears in the code but can not.

Thanks for the help.

Regards!

Formatting rows as summary

I am using a grid with bound rows and a summary row. I would like to also format one of the bound rows to look like a summary row.
Is there a simple way to do this?

I've tried setting the cell element ThemeRole to "GridSummaryCellElement" in the CellFormatting event, but it didn't work

Using AggregateExpression and GridViewSummaryItem

Hey all,

I have run into an issue using AggregateExpressions with GridViewSummaryItems.

If I use the following method and Sum(Foo2) is 0, I will obviously get a Divide by Zero exception. Is there anyway handle this when using AggregateExpressions or will I have to use the CustomSummaryItem method as described here?

Dim summaryItem As New GridViewSummaryItem()
summaryItem.Name = "Foo"
summaryItem.AggregateExpression = "(Sum(Foo) / Sum(Foo2)"

Too clarify, I have already got the desired output (percentage of the sums of two other columns in my grid) using the CustomSummaryItem, but I would rather use AggregateExpressions if possible as it's cleaner and requires less code.

Thanks!

[Solved] New toolwindow docked in splitcontainer at runtime

I have a scenario where I have a toolwindow docked on the left hand side of the document. I have a splitcontainer loaded just to the right of this. At runtime I am dynamically creating a new toolwindow and wish to position the new window at the top of the split containter, not the top of the document. I am using the following code to load the new toolwindow:

                ToolWindow windowPT = new ToolWindow();

                windowPT.Text = "PhoneTrak Dashboard";
                windowPT.Name = "twPhoneTrak";
                windowPT.DockState = DockState.Docked;

                rdMain.DockWindow(windowPT, DockPosition.Top);

Please see attached images for current placement vs. desired placement.

Thanks in advance!
