Text Not Showing

I have added Text to the carousel image and set the Text to be displayed as textaboveimage - and tried a number of the other options as well - and I cannot see any of the text....

It's not long text either - often just one word.

What am I doing wrong to cause the text not to appear above the image.

I should also mention that the images are 128 x 128... so it's possible that the text is 'under the image' - how do I cause the text to be shown above the image?

I also tried to set the Text Position Offset Height to 140 to see if that would work but still - no visible text.

Can anyone help with this?

DragDrop event in GridView

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];

}

on enter key copy cell values from previous row

Hi,
to facilitate and speed up insert row, when user press enter key all blank cell in current row must be copied from same cell (same column) of previous row.

At the begin the grid is blank, it not have datasource but only template for columns, user can add row by new row grid feature.

I have some problem when the edit row is the new row (not jet added to rows grid collection) and cell is in edit mode.
I try to create a custom GridBehavior to do this, but if row in edit is the new row i can't access it.

Thank you very much.
