Hi everyone,

This is my first time working with the ribbon bar. I created a ribbon form and then added a tab and then a group. It looks fine in the default theme. When i change the theme to one on the right side of the image it looks like the bottom part of the group is cut off. Is this right? Also, why does the title text look like it does?

Thanks for your help!

Editor Control with AutoComplete support for "contains" logic

Hi,

Do you offer a control that is ideally TextBox -based that has AutoComplete functionality, much like "out-of-box" TextBox, but with additional support for "contains" logic, in addition to "starting with" logic?

For example, when typing in "p", both "Pear" and "Apple" would be suggested, as both contain "p".

Or optionally, it could be a ComboBox - based control, but allowing free-form entry by user without having to add entered value to Items collection.

Is my current understanding correct that you guys currently don't have this as TextBox-based, according to: http://www.telerik.com/community/forums/winforms/editors/intellisense-autocomplete-in-textbox-like-in-outlook.aspx ? And that your TextBox only shows one suggestion, even though there could be multiple options for autocomplete?

Thanks!

Telerik.WinControls.UI.DataGroup.Header

Hi,

I have a grid with groupings by customer ID. When I iterate in code through the data groups, the header property is returning the value but the first character is truncated off.

the Text on the group header band shows "Customer ID: 1235" but when i check the group.header value, its returning "235". Every group that has a number does this. the string headers seem to work ok.

Pass Datatable Object to Cell C#

Hi,

I tried to display some charts in a Grid like the attached picture, so I need to pass the data to the cell and I used following code:

Random r = new Random ();

GridServer.Rows.Add ("1");

for (int i= 1; i <= 16; i++)

{

DataTable table = new DataTable ();

table.Columns.Add ("DateTime", typeof (DateTime));

table.Columns.Add ("Value", typeof (double));

table.Rows.Add (DateTime.Now, r.Next (100));

table.Rows.Add (DateTime.Now.AddSeconds (30), r.Next (100));

table.Rows.Add (DateTime.Now.AddSeconds (60), r.Next (100));

table.Rows.Add (DateTime.Now.AddSeconds (90), r.Next (100));

table.Rows.Add (DateTime.Now.AddSeconds (120), r.Next (100));

table.Rows.Add (DateTime.Now.AddSeconds (150), r.Next (100));

GridServer.Rows[0].Cells[i].Value = table;

}

Basing on the definition, the type of GridServer.Rows[0].Cells[i].Value is object

public class GridViewCellInfo : IEquatable<GridViewCellInfo>

{

// Summary:

// Gets or sets the value.

public object Value { get; set; }

//

}

So the GridServer.Rows[0].Cells[i].Value should get the reference of my DataTable, but the actually value of Value is a empty string.

Is this a bug or anything wrong in my code?

Thanks

Charles

Problems in printing grid with multiline field

I have a gridView in a winform. I have set one of the column "Note" to:
wraptext= true
multiline= true

This is my print button:

private void BtnPrint(object sender, EventArgs e)

{

GridPrintStyle style = new GridPrintStyle();

style.FitWidthMode = PrintFitWidthMode.FitPageWidth;

style.PrintHeaderOnEachPage = true;

this.radGridView1.PrintStyle = style;

this.radGridView1.PrintPreview();

}

despite the above, the result I get, see picture attached, is not the expected one.The multilines field doesn't shows properly the content. Part of the text is out of the visible box.
I have tried with several printers but the problem is always the same.
What I can do to solve this problem?

How to get themes working?

Hi, I have this old winforms application that I am updating.
I want the RadGridView I have just added to it to use a different theme than default, but whatever I do, nothing happens..

I tried setting the ThemeName on the grid to "TelerikMetro", I also tried;

ThemeResolutionService.ApplicationThemeName = "TelerikMetro";

That sounded like the right thing to do after googling a bit - didn't work either from Program.cs or main.cs (the form with the grid)

I just don't get it.. how the heck do you get themes to work?

I've added references to Telerik.WinControls, t.w.gridview, t.w.themes.telerikmetro,t.w.ui, t.w.ui.design, t.windows.controls, t.w.c.data, t.w.c.datavisualization, t.w.c.gridview

This is driving me off the edge at the moment :(

Drag and drop files from the Desktop (or Windows Explorer) to RadListView

Hello guys, I hope you are doing great.

I'm working on a WinForms project. One of the requirements is to drag files from the Desktop (or Windows Explorer) and drop them on a RadListView component.

I set the AllowDrop and AllowDragDrop properties of the my listView object, and then I added the following events:

private void listView_DragEnter(object sender, DragEventArgs e)

{

MessageBox.Show("DragEnter");

}

private void listView_DragDrop(object sender, DragEventArgs e)

{

MessageBox.Show("DragDrop");

}

When I drag an item from the Desktop and enter the listView area, I get the "DragEnter" message. If I comment that code out, and then drop an item on the listView, I don't get the "DragDrop" message.

My first question is: is it possible to achieve what I'm trying to do? And if it is possible, my second question is: what am I doing wrong?

I created a small test project to isolate the situation. The following is the complete code of the form class:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

using Telerik.WinControls;

namespace DragFromDesktop

{

public partial class DragFromDesktopForm : Telerik.WinControls.UI.RadForm

{

public DragFromDesktopForm()

{

InitializeComponent();

}

private void DragFromDesktopForm_Load(object sender, EventArgs e)

{

}

private void closeButton_Click(object sender, EventArgs e)

{

this.Close();

}

private void listView_DragEnter(object sender, DragEventArgs e)

{

//MessageBox.Show("DragEnter");

}

private void listView_DragDrop(object sender, DragEventArgs e)

{

MessageBox.Show("DragDrop");

}

I'm also attaching an example of how the form looks like. The big white square is the list view which I want to drop the items to.

Thanks in advance.

Best regards,

Alejandro

CompositeFilterExpression not filtering as expected

I have a grid which has to be filtered programatically based on user entry. More than one column has to be filtered and each column may have more than 1 value to be filtered upon. Like say, Col1, Col2, Col7, Col8 has to be filtered on {1,4}, {1,38}, {78,65} & {1,0} respectively.

I have written the below code for this but looks like it filters only on the last set of values i.e. 4,38,65,0.

public static void SetGridFilterComposite(RadGridView gridView, Dictionary<string, List<int>> filterValues)

{

CompositeFilterDescriptor mainDescriptor = new CompositeFilterDescriptor();

List<int> values = null;

if (filterValues == null || filterValues.Count == 0) return;

ClearGridFilterColumns(gridView);

foreach (string column in filterValues.Keys)

{

CompositeFilterDescriptor columnDescriptor = new CompositeFilterDescriptor();

if (gridView.Columns.Contains(column))

{

values = filterValues[column];
