Questions on UI for WinForms Forum

The attached picture shows a UI that I have been copying. In my version of this UI there is a FlowLayoutPanel with my user controls on it. On the right (what I want to build now) is what I think is a ToolWindow. This ToolWindow cannot be moved; it's docked on the right. That's where it stays. It can be pinned or unpinned; nothing else. It expands out over the FlowLayoutPanel.

I think RadDock is what I should use and, if so, I'm just a couple details away from making what I want. If there's a better choice I'd like to hear (read) it. But, if not:

1. How do I make a ToolWindow stay docked and not allow the user to move it anywhere?

I found the forum response for the buttons so that there is only the pin:

toolWindow1.ToolCaptionButtons =

ToolStripCaptionButtons.AutoHide;

2. How do I make that "Pin" button start out not pinned? I want the ToolWindow to be collapsed.

3. How do I get a content area in the RadDock that doesn't have tabs or anything? Basically, I want a rectangular shape that contains my user controls (in a scrolling container) and the ToolWindow...no tabs, no titles, nothing else.

Thank you,
Gary

DateTime Picker and Null

I am deriving a custom control from the RadDateTimePicker (version: 2011.1.11.419 or Q1 2011) trying to get it to work with null values. We need it to display an empty string when bound to a null value. For the most part this is working with the code below.

public new DateTime? Value

{

get

{

if (_value.HasValue)

return _value.Value;

return _value;

}

set

{

if (_value != value)

{

_value = value;

OnValueChanged(new EventArgs());

}

public new DateTime? NullDate

{

get { return _nullDate; }

set { _nullDate = null; }

}

void AmDateTextBox_ValueChanged(object sender, System.EventArgs e)

{

if (this.Value == null)

{

this.SetToNullValue();

}

else

{

this.DateTimePickerElement.TextBoxElement.TextBoxItem.Text = this.Value.Value.ToShortDateString();

}

If I am viewing a record with a date value and change to another record with a date value all is well. If I then change to a record with a null date it displays fine. But when I change back to a record with a date value nothing is displayed. I would also like to remove the hard coded format in the Value Changed event handler. I am binding RadDateTimePicker.Value to a DateTime? field on Csla objects not a data table.

Thanks,

Track event when used 'insert' from contextmenu

Hi,

I try to hook an event that signals the value changing, when I am using the 'Insert' (or 'Einfügen' in german) function from the standard context menu. Neither 'CellValueChanged' is fired nor 'ValueChange' . I need to track cause of the database update. Can you help?

RadListView adding new event handler

I am using Q1 2011 Reporting on VS 2012. I want to add new event to RadListView but I am getting an error. Here is the part of my code. Error line is in bold.

private Telerik.WinControls.UI.RadListView lvRules;

private void lvRules_SelectedItemChanged(object sender, ListViewItemEventArgs e)
{
ListViewDataItem item = e.Item;
if (item == null)
return;
DbSpamRule rule = (DbSpamRule)item.Tag;
Rule2FormObjects(rule);
}

this.lvRules.SelectedItemChanged += new Telerik.WinControls.UI.ListViewItemEventHandler(this.lvRules_SelectedItemChanged);

How can I fix this error?: Cannot implicitly convert type 'Telerik.WinControls.UI.ListViewItemEventHandler' to 'System.EventHandler'

Any suggestions?

ListView and DragDropService

I have a ListView in IconMode which supports drag & drop for reordering the items by using the ListViewDragDropService:
dim myDDService as new ListViewDragDropService = ListView.ListViewElement.DragDropService
It works fine. Now I try the same with a databound ListView but I doesn't react on dragging. When I remove the databinding and fill the listview manually with the items, drag and drop works.

PageView Control Data Binding

I am developing a WinForms application using a RadPageView control with eight tabs. On each tab I have a mix of RadTextBox and RadDropDownList controls all bound to a object using a BindingSource control. When I bind an object to this datasource the SelectedValue on certain drop downs don't always bind on pages after the first one. As soon as I click on the page the SelectedValue updates and it displays the correct value. There doesn't seem to be any pattern to which drop downs have this problem and the ones that have the problem seem to periodically change.

Does anyone know why this happens or if there is a way around it? The problem it is causing me is that when I call ValidateChildren on the form the validation is happening without the values being correct, but when I switch to the page with the error the field is correct but still shows the validation error.

Upgrading from 2009

Hi,

I'm an older user (2009) and I have purchased an actual license (3013.1).
I want to use Upgrade Tool but I can't do what it says in the links...

http://www.telerik.com/help/winforms/pageview-upgrading-to-radpageview.html

"This article is valid for RadControls for WinForms versions prior to Q2 2011 SP1 inclusive. The Upgrade Tool can be used only if started from the SmartTag of the obsolete controls. Since these controls have been removed in Q3 2011, their respective Upgrade Tools are not available as well. In case you want to use the tools, please upgrade/downgrade to Q2 2011 SP1 (v2011.2.11.831)"

The question is, how could I upgrade first to Q2 2011 SP1, and then to 2013.1?

Thank,
Francisco
