Hi,
we are using telerik Radgridview - version 2010.3.10.1215 (i got it by viewing the properties of the dll under ->reference part of the solution explorer) for winforms application. Our requirement is, the user should drag multiple rows from Radgridview and drop it in a radtreeview node. Currenly we are able to move only one record from grid view to treeview node. After researching for some quite we are still unable to find a solution for this. Any help will be appreciated lot.

BusinessObject Databinding

I have an application that was working fine and then upgraded to the latest version without reading the release notes. I know....dumb...but wanted to keep current.

The problem is with databinding.
I have the following business object that has child colletions for ProductCategories and Locations:

public class Customer

{

private string name;

private List<ProductCategory> categories;

private List<Location> locations;

... with their associated public properties;

}

the ProductCategories class also has a child collection of products like so..

public class ProductCategory

{

private string categoryName;

private List<Product> products;

....

}

public class Product

{

private string productName;

......

}

I would like that tree to display the following:
Customer Name
     Product Categories
          Product Category 1
               Product Name 1
               Product Name 2
          Product Category 2
               Product Name 1
               Product Name 2
Locations
      Location Name 1
      Location Name 2

When I retrieve the information about the customer the child collections get loaded up in a List<Customer> custList

How do I set that up?
Do I use the RelationBindings colletion? If so, how?

Thanks

Weird problem with Property Builder

Hello!

I have upgraded to v.2011.1.11.419 and got a weird problem with the Property Builder (Visual Studio 2008).

It can be reproduced easily. First, I create a simple form with a RadGridView. The Form1.Designer.cs file is:

namespace Test1

{

partial class Form1

{

/// <summary>

/// Required designer variable.

/// </summary>

private System.ComponentModel.IContainer components = null;

/// <summary>

/// Clean up any resources being used.

/// </summary>

/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>

protected override void Dispose(bool disposing)

{

if (disposing && (components != null))

{

components.Dispose();

}

base.Dispose(disposing);

}

#region Windows Form Designer generated code

/// <summary>

/// Required method for Designer support - do not modify

/// the contents of this method with the code editor.

/// </summary>

private void InitializeComponent()

{

this.radGridView1 = new Telerik.WinControls.UI.RadGridView();

((System.ComponentModel.ISupportInitialize)(this.radGridView1)).BeginInit();

((System.ComponentModel.ISupportInitialize)(this.radGridView1.MasterTemplate)).BeginInit();

this.SuspendLayout();

//

// radGridView1

//

this.radGridView1.Dock = System.Windows.Forms.DockStyle.Fill;

this.radGridView1.Location = new System.Drawing.Point(0, 0);

this.radGridView1.Name = "radGridView1";

this.radGridView1.Size = new System.Drawing.Size(284, 264);

this.radGridView1.TabIndex = 0;

this.radGridView1.Text = "radGridView1";

//

// Form1

//

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

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

this.ClientSize = new System.Drawing.Size(284, 264);

this.Controls.Add(this.radGridView1);

this.Name = "Form1";

this.Text = "Form1";

((System.ComponentModel.ISupportInitialize)(this.radGridView1.MasterTemplate)).EndInit();

((System.ComponentModel.ISupportInitialize)(this.radGridView1)).EndInit();

this.ResumeLayout(false);

}

#endregion

private Telerik.WinControls.UI.RadGridView radGridView1;

}

Then I open the Designer View and click "Open Property Builder" for a grid. The Property Builder window blinks quickly and the following message box is shown:

---------------------------
Properties Window
---------------------------
Must specify valid information for parsing in the string.
---------------------------
OK
---------------------------

The Form1.Designer.cs file becomes the following:

namespace Test1

{

partial class Form1

{

/// <summary>

/// Required designer variable.

/// </summary>

private System.ComponentModel.IContainer components = null;

/// <summary>

/// Clean up any resources being used.

/// </summary>

/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>

protected override void Dispose(bool disposing)

{

if (disposing && (components != null))

{

components.Dispose();

}

base.Dispose(disposing);

}

#region Windows Form Designer generated code

/// <summary>

/// Required method for Designer support - do not modify

/// the contents of this method with the code editor.

/// </summary>

private void InitializeComponent()

{

this.MasterTemplate = new Telerik.WinControls.UI.RadGridView();

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

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

this.SuspendLayout();

//

// MasterTemplate

//

this.MasterTemplate.Dock = System.Windows.Forms.DockStyle.Fill;

this.MasterTemplate.Location = new System.Drawing.Point(0, 0);

this.MasterTemplate.Name = "MasterTemplate";

this.MasterTemplate.Size = new System.Drawing.Size(284, 264);

this.MasterTemplate.TabIndex = 0;

this.MasterTemplate.Text = "radGridView1";

//

// Form1

//

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

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

this.ClientSize = new System.Drawing.Size(284, 264);

this.Controls.Add(this.radGridView1);

this.Name = "Form1";

this.Text = "Form1";

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

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

this.ResumeLayout(false);

}

#endregion

private Telerik.WinControls.UI.RadGridView radGridView1;

private Telerik.WinControls.UI.RadGridView MasterTemplate;

}

I tried to uninstall the RadControls at all and install them from scratch. This did not help.

So, could you please help me with a work around this problem? I use a lot of grids in ny project, so, it would be a pity to miss the Property Builder feature.

Thank you.

Column Header Language

Hi,
I have a radform with a gridview control. The "Localizable" property in the RadForm is true and there are only two columns in the gridview. In desgin time, I input the column header text for each column in grid. Then, I change the "Language" in the form and input the Column Header Text in other language.
However, after I switch back language to original, all the column header text I input before were missing.
Then, I checked the resx files for those two language and found that the "GridViewTextBoxColumn" in those files are different.

The resx file in original language (RadForm1.resx):

<xsd:schema id="root" xmlns="" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">

Then, I switch the form language back to original language and find that in "RadForm1.zh-Hant.resx" file, the data name for grid column had changed to "GridViewTextBoxColumn3" instead of "GridViewTextBoxColumn1". So, the column header text can't display in original language.

[Solved] "Click here to add anew row" click on childrow exception

Hello,

I've met this morning a special behavior where an exception occurs.

I create a little project for it, and it's really easy to do it again.
(Project here)

Simply launch an instance of this project, click on little "+" to display Childrows and click on "click here to add a new row" in child table

You'll get an null reference exception

Any workaround for letting user adding a childrow?

Regards
