Hi

1. I need to be able to tell from the DragEventArgs arguments in the DragDrop event of the GridView, which row the user is "dropping" on.

I tried:

dgvPlaylistRegionMedia.GetChildAtPoint(new Point(e.X, e.Y));

but it returns null the whole time.

2. Also, it would be nice to give some sort of indication to the user where he would be "dropping", for e.g. a line between row 2 and row 3 if he's "hovering" between those 2 rows, or even a line after the last row to indicate that he would be adding it after the last row if he's "hovering" past the last row. Any ideas?

Kind regards

Ralph

List of dynamic objects as DataSource

I'm using Telerik WinControls 2014.3.1104.40 in a C# environment.

I have a gridview that has a number of preset columns, as well as zero or more additional, user-defined columns. I need a way to load this data into the grid.

Currently, I am trying to use C# "dynamic" objects, in hope that the FieldName property of each column will access that field of the dynamic object; but the grid does not appear to load anything from a list of dynamic objects.

There should be data loaded into the cells, but they show up blank. Here is a sample of the code that is not working:

private void LoadData()

{

radGridView1.DataSource = new List<dynamic>()

{

CreateDynamicObject(1),

CreateDynamicObject(2),

CreateDynamicObject(3),

};

}

private dynamic CreateDynamicObject(int id)

{

dynamic ret = new ExpandoObject();

ret.Id = id;

ret.Prop1 = "Property 1: " + id;

ret.Prop2 = "Property 2: " + id;

return ret;

}

If List<dynamic> data sources are not supported, what other method would be most similar?

[Solved] List View in Cell of GridView

Hello

I succeeded to put a listview in a cell of a grid. But I have some problems with it.

1. Why the first listview item is always highlighted.
2. How can I add the possibility to work with keyboard to select some listview items instead of mouse.

public class CheckListBoxCellElement : GridDataCellElement

{

public CheckListBoxCellElement(GridViewColumn column, GridRowElement row)

: base(column, row)

{

}

RadListViewElement radListElement;

protected override void CreateChildElements()

{

base.CreateChildElements();

radListElement = new RadListViewElement();

radListElement.ShowCheckBoxes = true;

radListElement.AllowArbitraryItemHeight = true;

radListElement.ViewType = ListViewType.IconsView;

radListElement.VisualItemFormatting += new ListViewVisualItemEventHandler(radListElement_VisualItemFormatting);

radListElement.ItemCheckedChanged += new ListViewItemEventHandler(radListElement_ItemCheckedChanged);

this.Children.Add(radListElement);

}

void radListElement_VisualItemFormatting(object sender, ListViewVisualItemEventArgs e)

{

BaseListViewVisualItem lvi = e.VisualItem as BaseListViewVisualItem;

lvi.DrawBorder = true;

lvi.DrawFill = true;

lvi.CanFocus = true;

}

void radListElement_ItemCheckedChanged(object sender, ListViewItemEventArgs e)

{

if (e.Item.CheckState == Telerik.WinControls.Enumerations.ToggleState.On)

{

PropertyValue val = (PropertyValue)e.Item.DataBoundItem;

val.Selected = true;

}

else

{

PropertyValue val = (PropertyValue)e.Item.DataBoundItem;

val.Selected = false;

}

protected override void SetContentCore(object value)

{

IList list = (IList)value;

radListElement.DataSource = list;

radListElement.DisplayMember = "Name";

radListElement.ValueMember = "ID";

}

protected override Type ThemeEffectiveType

{

get

{

return typeof(GridDataCellElement);

}

public override bool IsCompatible(GridViewColumn data, object context)

{

return data is CheckListBoxColumn && context is GridDataRowElement;

}

public class CheckListBoxColumn : GridViewDataColumn

{

public CheckListBoxColumn(string fieldName)

: base(fieldName)

{

}

public override Type GetCellType(GridViewRowInfo row)

{

if (row is GridViewDataRowInfo)

{

return typeof(CheckListBoxCellElement);

}

return base.GetCellType(row);

}

public class Data

{

public string Name { get; set; }

public IList Field { get; set; }

}

public partial class MYForm : Form

{

public MYForm()

{

InitializeComponent();

Init();

}

private void Init()

{

GridViewTextBoxColumn column1 = new GridViewTextBoxColumn("Name");

ksGrid.Columns.Add(column1);

CheckListBoxColumn column2 = new CheckListBoxColumn("Field");

ksGrid.Columns.Add(column2);

column2.Width = 250;

ksGrid.AutoGenerateColumns = false;

ArrayList list = new ArrayList();

IList values1 = new ArrayList();

values1.Add(new PropertyValue() { ID = 1, Name = "Blue" });

values1.Add(new PropertyValue() { ID = 2, Name = "Yellow" });

values1.Add(new PropertyValue() { ID = 3, Name = "Red" });

Data data1 = new Data { Name = "Color", Field = values1 };

list.Add(data1);

IList values2 = new ArrayList();

values2.Add(new PropertyValue() { ID = 4, Name = "M" });

values2.Add(new PropertyValue() { ID = 5, Name = "L" });

values2.Add(new PropertyValue() { ID = 6, Name = "XL" });

Data data2 = new Data { Name = "Size", Field = values2 };

list.Add(data2);

ksGrid.DataSource = list;

object ob = ksGrid.Rows[1];

}

ScrollablePanel not showing scrollbar

Hi there,

i have the following problem:

I have a RadScrollablePanel.

Inside this Panel i added two RadGroupBox-Controls.

The first is positioned in the upper left corner with Anchor = Left Top Right and minimum size of 300

The second is positioned in the upper right corner with Anchor = Top Right.

Now when resizing my Form, i expected when the Minium size is reached, the Scrollable Panel should show scrollbar.

I added an example project

Thanks Florian Keller
