[Solved] Using RadContextMenu instead in of standard context menu in a derived control

I have a control that is derived from RadLabel. Inside this control I would like to add a RadContext menu instead of the standard Windows Forms context menu. What's the proper way to do this inside my control? I don't want to rely on a ContextMenuManager on the parent form but instead encapsulate everything in my control.

Regards

Erwin

Problem at RibbonBar Element

I have a c# aplication where I have to build programaticly many RadImageButtonElements from scratch. When I move the mouse over the RadImageButtonElement the button doesn't highlight if I hover with the mouse over the button. When I add a new RadImageButtonElement from RadRibbonBar when I hover over with the mouse I see that the RadImageButtonElement will be highlighted. Can you please help me what to add to my my code so that my RadImageButtonElement can be highlighted as well. Thank you for your time and if it is not the correct forum please move this thread to the correct forum.

At RadRibbonBar you can add an RadImageButtonElement through the Edit Items functionality. I have to create a new RadImageButtonElement programmability and cannot make the item highlighted when my mouse hovers over the RadImageButtonElement. When I add an RadImageButtonElement through Edit Items functionality then I can highlight the RadImageButtonElement when I hover with my mouse over the ribbonbar element.

I added the code:

RadImageButtonElement oButton = new RadImageButtonElement();

// add image to the button and other things

oButton.Text = oOperation.ToString();

oButton.DisplayStyle = DisplayStyle.ImageAndText;
oButton.TextImageRelation = TextImageRelation.ImageAboveText;
oButton.Image = oButton.ImageClicked = oButton.ImageHovered = GetButtonImage(oOperation, true);

rrbgOptions.Items.Add(oButton);

rrbgOptions is the form RadRibbonBarGroup . When I run my program inside the RadRibbonBarGroup the image buttons created with the RadImageButtonElement apears but when I move my mouse over the buttons they don't highlight.

When I add the Image button on using the form RadRibbonBarGroup Edit Items controls to create the Image buttons the buttons will be highlighted when I move my mouse over them.

Can you please help so that the Image Buttons created programaticly as shown as above can be highlighted when I move the mouse over them.

Thank you.

Areaseries: Use horizontal axis as origin of coloring

Hi,

I am trying to snap the coloring of area series around to horizontal axis. The first pic (Area Coloring) illustrates what I've got, Area Color Goal what I'd like to see. I've already tried to split negative values from positives, like this http://www.telerik.com/forums/set-the-color-of-negative-value-on-areaseries, but the result is the same in winforms.

Please advise.

Best Regards.

DropDownList not consistently showing the list window

Hello Support,

I am using Telerik for Winforms version 2015.2.728.40. We are testing our application using Remote Desktop Services in Windows Server 2012. We are experiencing an issue with all the drop downs in that the drop down window does not consistently show. Most times, the display window for the drop down lists are truncated, even though the items are still selectable.

I created a sample application with one form and one dropdownlist and was able to reproduce this behavior with Telerik version 2015.2.728.40.

I updated the sample to version 2016.2.608.40 and only saw the issue once.

I'm wondering if there is anything I can do to make the dropdownlist list show correctly with version 2015.2.728.40?

Thanks

Francisco

Iterate Rows with wrong Results

I tried to use GridView in Master/Details Mode to get data from MongoDb Server.

And as the pic shows, I get the Id and the name from a Collection of Users, then I Iterate the parent Rows to get the Id and I fetch in the 2nd Colection of Product to get the details of each user.

In the server, the 1st user have only 1 product but in the pic it show it 3 times with 2 tables.

So how to get the right results and how work with Master/Detail GridView

namespace TelerikGridView

{

public partial class Form2 : Form

{

List<WatchTblCls> wts;

List<UserCls> user;

List<SymboleCls> symb;

public Form2()

{

InitializeComponent();

wts = new List<WatchTblCls>();

user = new List<UserCls>();

symb = new List<SymboleCls>();

}

private async void button1_Click(object sender, EventArgs e)

{

// add user into datagridview from MongoDB Colelction Watchtbl

var client = new MongoClient("mongodb://servername:27017");

var database = client.GetDatabase("WatchTblDB");

var collectionWatchtbl = database.GetCollection<BsonDocument>("Watchtbl");

var collectionUser = database.GetCollection<BsonDocument>("Users");

//wts = await collectionWatchtbl.Find(x => true).ToListAsync();

//Get User Data

var filter = new BsonDocument();

using (var cursor = await collectionUser.FindAsync(filter))

{

while (await cursor.MoveNextAsync())

{

var batch = cursor.Current;

foreach (var document in batch)

{

user.Add(new UserCls()

{

Id = ObjectId.Parse(document["_id"].ToString()),

Name = document["Name"].ToString()

});

}

//Get WatchTbl Data

using (var cursor = await collectionWatchtbl.FindAsync(filter))

{

while (await cursor.MoveNextAsync())

{

var batch = cursor.Current;

foreach (var document in batch)

{

wts.Add(new WatchTblCls()

{

Id = ObjectId.Parse(document["_id"].ToString()),

UserId = document["userId"].ToString(),

WID = document["wid"].ToString(),

Name = document["name"].ToString()

//Symbole

});

}

this.radGridView1.DataSource = user;

this.radGridView1.Columns["fbId"].IsVisible = false;

this.radGridView1.Columns["Pass"].IsVisible = false;

}

GridViewTemplate childTemplate;

private GridViewTemplate CreateChildTemplate()

{

childTemplate = new GridViewTemplate();

this.radGridView1.Templates.Add(childTemplate);

GridViewTextBoxColumn column = new GridViewTextBoxColumn("wid");

childTemplate.Columns.Add(column);

column = new GridViewTextBoxColumn("name");

childTemplate.Columns.Add(column);

childTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

return childTemplate;

}

private void Form2_Load(object sender, EventArgs e)

{

GridViewTemplate childTemplate = CreateChildTemplate();

this.radGridView1.Templates.Add(childTemplate);

childTemplate.HierarchyDataProvider = new GridViewEventDataProvider(childTemplate);

}

private void radGridView1_RowSourceNeeded(object sender, GridViewRowSourceNeededEventArgs e)

{

foreach (GridViewRowInfo item in radGridView1.Rows)

{

var itll = item.Cells["id"].Value.ToString();

foreach (var itemWts in wts)

{

if (itll == itemWts.UserId.ToString())

{

GridViewRowInfo row = e.Template.Rows.NewRow();

row.Cells["wid"].Value = itemWts.WID.ToString();

row.Cells["name"].Value = itemWts.Name.ToString();

//symbole

e.SourceCollection.Add(row);

}

public class WatchTblCls

{

[BsonId]

public ObjectId Id { get; set; }

public string UserId { get; set; }

public string WID { get; set; }

public string Name { get; set; }

public List<SymboleCls> Symbols { get; set; }

}

public class UserCls

{

[BsonId]

public ObjectId Id { get; set; }

public string fbId { get; set; }

public string Name { get; set; }

public string Pass { get; set; }

}

public class SymboleCls

{

[BsonId]

public ObjectId Id { get; set; }

public string Name { get; set; }
