Cannot edit

I have a simple GridView with editable columns, and sometimes (I can't reproduce it every time) after a "refresh" of the data (=> when I set the DataSource again) I can't edit values, for example I can't check checkboxes, and I even can't select rows...
Do you have an idea about what could prevent the grid to enter edit mode?

Modifying an Existing Theme

Hello telerik team,
I would like to edit existing Theme for our whole application - i read documentation page http://www.telerik.com/help/winforms/themes_workingmodifyingexisting.html and I wonder whether it's possible to "edit whole existing Office2007Black" theme - not just certain controls and then merge it into our .xml theme file.

Change Image When Disabled

What is the best way (or is there a way) to swap images when a RadImageButtonElement is on the ribbonbar. We would also like to keep the text the same color but have the control be disabled with a different image.

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 ?
