The text I'm displaying in the GridView is often much too long to fit in columns.

How do I display flyover- or ToolTip text as I move the mouse over the grid?

I don't see a HitTest property.

There are a lot of events, like
"ToolTipTextNeeded", "MouseMove", "CursorChanged" but I don't know how to use the "e" argument from those events to retrieve the cell content the cursor is over.

I'm sure there is a most efficient way of doing this.

Charts not displaying correctly

Hello,

Telerik v2013 "UI for Winforms"
.Net 3.5
Visual Studio 2008

We have a .Net desktop application built using Visual Studio with Telerik UI for WinForms integrated. We are using the Chartview feature to show user some charts. However they are not displaying correctly and we cannot identify why.

We have set label mode to Top, it shows the label correctly for positive values but, it should display the bar lables at bottom side in case of negative values. We used radChartView control and belowbarSeries properties.

barSeries.ShowLabels = true;

barSeries.LabelMode = BarLabelModes.Top;

Fig1 attached shows our current chart with the incorrect label positioning
Fig2 attached shows how we would like the chart to display (a mockup).

Please help to explain how we can achieve this in the chart?

Thanks

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!

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!
