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];

FilterDescriptor filterDescriptor = new FilterDescriptor();

foreach (int value in values)

{

filterDescriptor.PropertyName = column;

filterDescriptor.Operator = FilterOperator.IsEqualTo;

filterDescriptor.Value = value;

columnDescriptor.FilterDescriptors.Add(filterDescriptor);

}

columnDescriptor.LogicalOperator = FilterLogicalOperator.Or;

mainDescriptor.FilterDescriptors.Add(columnDescriptor);

}

mainDescriptor.LogicalOperator = FilterLogicalOperator.And;

mainDescriptor.IsFilterEditor = true;

gridView.FilterDescriptors.Add(mainDescriptor);

}

An easy way for a user to resize a control?

I am working on a Winform program, and I can't believe there isn't an easier way to accomplish what I'm trying.

Basically, I want to display an image that will always be 640x480. Then, I want to have another control on top of it that is nothing more than a selection area that the user can change its size & location inside that 640x480 area, and it will report back its pixel size & x/y location.

Short of drawing all of the lines by hand and adding grips by hand, I can't seem to find an easy way to do this. Am I overlooking something?

Deploying - doubt

Hi again... :-)

I have read the FAQ : Redistributing Telerik RadControls for WinForms

But have some doubts regarding it.

There are two approaches right ? One is to make a single EXE file by merging the assemblies and the EXE of the program. And the other is to merge the assemblies into a single assembly. Am I right ?

If I want to go for the second approach, from where should I get the ILMerge program ?

Thanks in advance..

PS: Special thanks to Richard Slade for the continuous help he had provided to me. Really appreciate it... :-)

Anyone have a transparent theme for buttons?

Hello,

I need to place buttons in the ribbon bar and I only want to show any image and text. I do not want the border or background although it may be nice to have some border show when the mouse is over the button and clicked. I have read about the visual style builder but this is too complicated for me. Has anyone done this and have a DLL for this already? I would even pay someone to do this for me if possible.

Thanks,

Warren

RadTrackBar issue

When I set value using RadTrackBar.Value (using either code or designer), visually it doesn't properly corresponds to what is has to.
For example, Mininum = 20, Maximum = 200, Value = 100, but on the screen thumb is at the right end of control. Also, I think, that it is related - to set value higher than 100 - user has to move mouse out of control to the right side.
Controls version: 2013.3.1127.40

private void InitializeComponent()

{

this.radTrackBar1 = new Telerik.WinControls.UI.RadTrackBar();

((System.ComponentModel.ISupportInitialize)(this.radTrackBar1)).BeginInit();

this.SuspendLayout();

//

// radTrackBar1

//

this.radTrackBar1.Location = new System.Drawing.Point(13, 13);

this.radTrackBar1.Maximum = 200F;

this.radTrackBar1.Minimum = 20F;

this.radTrackBar1.Name = "radTrackBar1";

this.radTrackBar1.Size = new System.Drawing.Size(150, 17);

this.radTrackBar1.TabIndex = 0;

this.radTrackBar1.TickStyle = Telerik.WinControls.Enumerations.TickStyles.None;

this.radTrackBar1.Value = 100F;

//

// Form1

//

this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);

this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;

this.ClientSize = new System.Drawing.Size(292, 273);

this.Controls.Add(this.radTrackBar1);

this.Name = "Form1";

this.Text = "Form1";

((System.ComponentModel.ISupportInitialize)(this.radTrackBar1)).EndInit();

this.ResumeLayout(false);

this.PerformLayout();

}

Custom edit template

I'm really totally new to telerik.
I'm trying to create a form that has a grid view at the top section and at bottem an area for view, add, edit.
Each row in the grid shows basic information of some medical assessemnt. Clicking the row wil show all the information in the bottom area.
I can then edit or delete this information.
Clicking "add" will clear all the fields in the bottom section for inserting a new value.

Can anyone give me pointers on how to best approach with gridview. Example code will be a big help
