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; }

Telerik UI for Winforms or WPF ? which one would be the right option

Hi All

We are currently migrating one of our application from which is built on Third Party software( don't want to name it) to Telerik . The Application is an Windows Forms application and we need to get rid of the existing Third Party software and move that to Telerik. The existing applications has lot of Grids with features such as expand , collapse and filtering . Apart from that the application also contains Advanced Grid Grouping controls, Advanced Grid Navigation controls. It also contains Advanced Split Container's , Advanced Tab Page and Advanced Tree . I can see these controls available in Telerik UI for Windforms but not sure which would be best suitable product Telerik UI for Windforms or Telerik UI for WPF. Any Suggestions or Recommendations on the same will be highly helpful .

RadGridView Custom Base Class Setting Filter Defaults

We have created our own class based on the RadGridView. It has been themed and coded so all of our grids look and operate the same throughout the application. One of our requirements is to have the filtering row available at the top row of each grid.

Through theming I have removed the filter description text and the filter selection button. What we are left with is an empty filter row across the top of the grid that users can type into to filter the grid.

The issue is that the default filtering is set to "Contains" and our requirements are for it to be set to "Starts with". Every thing I see on this board shows how to set the default filtering to the columns after they have been set. I need to set this on the Grid base or master template so all columns will have this setting. Is this possible or do I have to wait until all columns are set and the roll through them each individually?

Here is a snippet of the base class code.

// CoreRadGrid
            this.Font = new System.Drawing.Font("Segoe UI", 8.25F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
            this.UseCompatibleTextRendering = false;
            this.MasterTemplate.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.None;
            this.MasterTemplate.EnableAlternatingRowColor = true;
            this.ThemeName = CoreTheme.ThemeName();
            this.RootElement.UseDefaultDisabledPaint = false;
            this.MasterTemplate.EnableFiltering = true;

            // set Default filter
            this.MasterTemplate.FilterDescriptors.Clear();
            FilterDescriptor filter = new FilterDescriptor();
            filter.Operator = FilterOperator.StartsWith;
            filter.IsFilterEditor = true;
            this.MasterTemplate.FilterDescriptors.Add(filter);

            this.MasterTemplate.MultiSelect = true;
            this.MasterTemplate.ViewDefinition = tableViewDefinition1;
            this.AutoGenerateColumns = true;

tile Image opacity

Hi.

The two halves of the screen shot are the same tile in different states.

The first, in "No" state, has a background image that is an opaque bitmap.

The second, in "Yes" state, shows the same tile, same background image, but its foreground Image is set to an opaque plain black bitmap painted with a solid white circle containing a green tick. This is to give a gray blind effect.

The bottom part of the tile is made up of several docked lightvisualelements to create a slider button.

I notice that the gray blind seems to be painted opaquely over the other elements, which I was pleased about as I actually wanted this effect. Is tile.Image always painted opaque? But I noticed that the bottom section of the tile isn't obscured or affected by by the blind, which again is what I want, but is this because of the presence of all the docking and visual elements?.

The problem is that I wanted the white, ticked circle to appear solid. Is this not possible by painting the circle as part of the image? Or do I need to add it as yet another docked visual tile element and set that one's image to the circle?

Adding a new form?

Winforms Q2 2013 SP1

Visual Studio 2013

I recently re-installed Telerik Winforms because I moved to a new PC on Windows 10

Also I now use VS2013 instead of VS2010

On my old PC, in VS2010 I could create a new radForm in my project by clicking "Add New..." and then select radForm from the telerik tab.

In my install on VS2013 I cannot find that anywhere.

Also the Telerik menu seems more empty than on my old pc.

I included pictures of both.

The telerik controls are included in the Toolbox

I uninstalled and re-installed again, but to no avail.

Please help,

regards,

Martin

Load on Demand

Hello,

The RadGridView's DataSource is set to a BindingSource. I am using the RadGridView.TableElement.VScrollBar.ValueChanged event to detect once the user has scrolled to a certain point. I then grab more items from the database and load them into the BindingSource and call BindingSource.ResetBindings(false) to refresh the items in the grid. This works fine unless the user is dragging the Thumb on the ScrollBar. After the event is triggered and more items are loaded, the Thumb is still focused and drag-able, but there is a large empty area below the last row in the grid. You can scroll down a lot further than the number of rows in the grid. Calling Refresh on the GridView does not remove the white area.

Is there a way to remove the white area this creates? Or maybe a better way to accomplish Load on Demand?

Unable to Drag And Drop DataSource Object field to Form

Hi,

I'm trying to perform operations as illustred in your article here: http://docs.telerik.com/data-access/developers-guide/data-access-model/advanced-model-tasks/developer-guide-domain-model-managing-advanced-project-data-source.

I can't! Object's three in the Data Source tool window seems to be "readonly", not draggable to the RadForm. They have aspect like in the first image attached. If I try to switch to a regular WinForm form, and I come back to the Designer, the aspect of the objects and field is slightly different, as in the second attachment, and I can drag them to the form succesfull.

Where is the trick? Why I can't with the RadForm form?

Thanks in advance.
