Hi

I have my own objects I want to bind to my grid and I want to make the column by myself because it’s not all the fields I want publish so I do like this

    
                        CompanyEOList Companylist = new CompanyEOList(WinXLFSecurity.XLFSecurity, WinXLFSecurity.CurrentDAL);  
        
                        Companylist.GetAll();  
        
                        gdCompanyList.MasterGridViewTemplate.AllowAddNewRow = false;  
        
                        gdCompanyList.MasterGridViewTemplate.AutoGenerateColumns = true ;  
        
                        gdCompanyList.MasterGridViewTemplate.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill;  
        
            gdCompanyList.MasterGridViewTemplate.Columns.Add(new GridViewDataColumn("Address", "Address"));  
        
                        gdCompanyList.DataSource = Companylist ;

where gdCompanyList is my grid. When I do like this and want filtering I can’t edit the filtering textbox. If I set the property AutoGenerateColumns to true it works. I have also tried to set the property AllowFiltering on the new column but that work either.

Telerik.WinControls.UI.GridViewDataColumn newColumn = new GridViewDataColumn("Name", "Name")

newColumn.AllowFiltering = true;

gdCompanyList.MasterGridViewTemplate.Columns.Add(newColumn);

What have I missing ?

One other thing. When I bind my own objects to the grid and the user is edit the objects how do I force the grid to save the change ?

Best regards

Binding to sub-objects with nulls problem

Hi,
I'm trying to reimplement a part of system using telerik gridView control.
I'm trying to bind a collection of objects to a dataGridView. This objects contains some other objects, that's why i want to use binding to sub objects. Everything works great, until a sub-object is a NULL. Then the whole row is not displayed. What I want to achive, is only not to display this column's value, and display all other values.
Is it possible using such a binding scenario?
Or should I do it in any other way (for example by initializing all these items with empty ones)? As far as these are database objects, I don't want to implement additional logic for adding such 'empty' items and deleting them before saving changes to DB.

I have similiar problem when using wpf version of this control.

Thanks for Your help in advance

RadMessageBox custom icon

I would like to use a custom icon with RadMessageBox. I see that the only overloaded calls to Show() which let you pass an icon .bmp file also require that you pass the previous window as the first parameter. I would like to use the same default window as the overloads to Show() that don't require this parameter. What can I use as the window that would give me the same results?

Fantastic work on the controls!

I have a legacy app which I was doing some updates to, so I thought I'd attach the telerik WinForms controls. I can't even express how pleased I am with the entire suite...my app looked like crap (admittedly) before. However now just by changing a few classes to inherit from Telerik and no other changes, the app looks 200% better and somehow runs faster!

Nice work guys, super happy

[Solved] GridView Column reordering problem

If I want to reorder columns in treeview, nothing happens. If I want to reorder columns in tableview, the property builder automaticaly closes. The only way reordering works is, if I first reorder columns in treeview (although it doesn't seem this does anything) and then reorder columns in tableview.

Closing an MDI Child Form

Hello,

I have forms inside document panes. The panes are created automatically for each MDI child form. I don't understand why document panes are working with form events. Isn't it logical that the little X button in the top right corner of the document pane causes the form to close? As a replacement for the normal close button of the form. If I don't want the form to close, just hide, I can always intercept the FormClosing event and cancel it, right?

The way it works now is very bad:
1) When I manually call the form Close method , the form closes, but the pane stays open. It should close as well since it is obviously not needed anymore.
2) When I click the document pane's X button it disappears, but the FormClosing/FormClosed events do not fire.

I've also read another post related to Activate and Deactivate events not firing and you say it's by design. I don't understand why it should be this way. Without the proper plumbing I have to write a lot more complicated code just to do all this basic stuff.

Can't you extend the document pane logic to support MDI child forms better? If not, is there another solution?

[Solved] Hidden items showing empty space

I have a RadComboBox displaying 70 user options (yes, it's a lot, but it's needed to replicate an electronic device that has all of these settings). To simplify the option selection for users, I'm using a second RadComboBox to allow the user to see only subsets of the 70 options in the first RadComboBox. Whether I use the Hidden or Collapsed visibility settings for the items I wish to hide, an empty space is shown in the drop-down list so the list is just as long, but mostly empty. Is this the intended behavior of the RadComboBox, or have I set this up incorrectly? Please don't tell me I supposed to load separate collections of items and have different selected item event code for each subset.

Thanks in advance for your help.
