ISerializable class in TreeNode Tag => XML status ?

Hi,

I have read with interest all the threads and comments on this forum regarding "serialization," with particular attention to exchanges in early 2008 such as :

http://www.telerik.com/community/forums/winforms/treeview/treeview-serializable.aspx#450955

Where Peter of Telerik commented : "You could try to create your own class that implements ISerializable and contains the data you want to store in the Tag property" in response to a query about trying to save strings stored in the Tag of a TreeNode as XML.

I've implemented a class that inherits from ISerializable, and has the mandatory Attributes and Security Permissions, and builds fine, but it breaks the TreeView XML parser or writer.

In my opinion the lack of abilitiy to save strings in Node tags is a real deficit in the TreeView.

Just curious if any changes are happening in this area of functionality. Obviously, as Peter demonstrated (see the linked article above), some objects, like DateTime are easily serializable. But Arrays of string, for example, while theoretically serializable, do not serialize ... but they do not cause an error, either.

Appreciate any clear statement about what is and is not serializable at this time, and in any future planned changes.

thanks, Bill

Dynamic Properties

I want to bind a generic list to a grid view but the columns can't all be defined as properties because they will be dynamic. Is this possible. It seems it should be since we can bind to a DataTable and other generic items which use this[string property] type accessorts.

MultiColumnComboBox - Filter Business Objects

Hey there,

I'm trying to use the MultiColumnComboBox from 2009.1.9.414 to do an AutoFilter on a DataSource that is an array of Buisness Objects.

I've done this before with a DataSource that is a DataTable, and it worked fine. The exact same code is failing to work altogether for Business Objects. Without the filter, I get the full thousand-odd account items returned. With the filter, I get nothing, no matter what I search for.

Other than stepping through my array and creating the DataTable myself, is there another method for doing this?

Sample code below:

                                AccountData[] data = this.GetData();         
                        this.cboSelectTaskAccount.DataSource = data;         
                     
                        // ... Set up my columns         
                     
                        if (this.cboSelectTaskAccount.EditorControl.MasterGridViewTemplate.FilterExpressions.Count < 1)         
                        {         
                            FilterExpression filter = new FilterExpression(         
                                this.cboSelectTaskAccount.DisplayMember,         
                                FilterExpression.BinaryOperation.AND,         
                                GridKnownFunction.Contains,         
                                GridFilterCellElement.ParameterName);         
                            filter.Parameters.Add(GridFilterCellElement.ParameterName, true);         
                     
                            this.cboSelectTaskAccount.EditorControl.MasterGridViewTemplate.FilterExpressions.Add(filter);         
                        }         

I'm hoping there's a fix for this in 2009.1.9.414, as the cost for refactoring to the latest version would be quite steep right now.

Thanks for your time.

GridViewComboBoxColumn value after selection becomes empty

I am using editable RAD grid view to bind some POCO and it has a GridViewComboBoxColumn as defined below

this

.gvTargetSelection.MasterGridViewTemplate.AutoGenerateColumns = false;

GridViewComboBoxColumn gvcbc = new GridViewComboBoxColumn("Priority");

gvcbc.DataSource =

new string[] { TargetGroupPriority.NiceToHave.ToString("g"), TargetGroupPriority.MustHave.ToString("g") };

gvcbc.DropDownStyle =

RadDropDownStyle.DropDownList;

gvcbc.Width = 100;

gvcbc.ReadOnly =

false;

gvcbc.ValueMember =

"Priority";

gvcbc.HeaderText =

"Priority";

gvcbc.FieldName =

"Priority";

this.gvTargetSelection.Columns.Add(gvcbc);

When the control renders, data is populated and which when double clicked exposes the combo box column with above two values [As shown in code above, data source.]

However when I select any value there and move mouse of the control, no longer anything is selected and cell is empty. If you double click again on the cell, data is there.

Am I missing here setting some default property etc ?

[Solved] ForeColor not used?

Hi,

I use a rad button.
All I want to do is to change the ForeColor depending on the situation.

Trying this I found - nothing happens.
So I tried in designer - also the same result.

Whatever I set for forecolor is ignored.

I do nothing more than a clean project - drag a button to it and try to change forecolor.

The button is nice blue (like menus) and the textcolor is darkblue - not changeable.

Regards

Manfred

How to create a cell with several controls ?

Hi everyone,

I have a big problem. I am working on a projct wich was designed in ASP.NET. We used Telerik for this project. We are now migrating the project in Winforms for performances reasons. But there is several things difficult to adapt, especially with GridViews.

In ASP.NET we had a GridView wich indicate the temperatures for each day of the weak (and other things). Each cell contains the different temperatures wich were noted this day. And for each temperature we can edit it (by clicking the temperature : it's a link) or delete it (by clicking the icon : it's a LinkImage). I don't know if I am clear so there is a picture : http://www.casimages.com/img.php?i=091012042545149095.gif.

How can I reproduce the same thing in WinForms. How can I add multiple controls (labels and picturebox) in the same cell and how can I deal with the click on each one ?

Thanks for your help because I'm stuck because of this.

Installing your VS 2010 WinForm preview ?

Hi,

using Vista Ultimate. SP1, VS Studio 2010 beta.

I downloaded the trial version of your shipping WinForms suite

"RadControls_for_WinForms_2009_2_9_903_trial.zip"

today, and installed it with no problem. The demo program runs fine (must be a WPF demo, I'd say from looking at the graphics and interface).

I want to try your WinForm controls in Visual Studio 2010 beta. You have two downloads available on the preview build site :

RadControls_for_WinForms_2009_2_9_903_trial.zip (Release notes)
RadControlsForWinForms.exe (Release notes)

Which I have downloaded. The zipped archive contains a "ReadMe" file which mentions installing the dll's manually in the GAC, but I am not clear what the relationship is between the .exe file and the files in the archive.

Should I un-install your trial version first before running the .exe file ?

A few simple instructions (I have searched your site thoroughly) for the correct installation procedure would be appreciated.

thanks, Bill Woodruff
