I have been working on styling an expander. When it's expanded, there is a line across the top that seperates the header area from the content area. Any way to remove this line?
I added this:
<Trigger Property="IsExpanded"
Value="True">
<Setter TargetName="Border"
Property="BorderThickness"
Value="0" />
</Trigger>
But it hide ALL of the header's border when the control is expanded. I just want to remove the lower portion of the header's border.
Thanks

Then you can't use a border, you are going to have to break up the control so you can manipulate the lower bound!

Why not? You can set the thickness on each side individually.

Then you can use the border and you have answered the question! I have not played with the border other than the minimum, I responded based on the question, I would have thought the OP would have explored that before asking the question, it seems so obvious. Silly of me!
Have 5 sisnce the OP does not seem to have worked out the response to a good answer.

Set BorderThickness to "1,1,1,0" in your trigger.

Hi
I use a ComboBox style (the style from msdn example), but I customized it to replace the standard popup with a datagrid.
The problem I have is I can't catch Key.Down with the event handler PreviewKeyDown.
The comboBox is defined with the style described.
It has to do with the template style applied on the comboBox.
Somehow the keydown is caught by the combobox, because I see for few ms the ItemBinding path in the textBox, but it is not caught in the code.
I have tried also to put in style somthing like with no success.
<EventSetter Event="PreviewKeyDown" Handler="OnPreviewKeyDown" />
any ideas how to solve it?
Is it possible to use my comboBox declared in xaml and override OnPreviewKeyDown in the code behind?
<ComboBox Name="comboBoxFunctions"
Style="{DynamicResource ComboBoxStyleDataGridMethods}"
Height="23" HorizontalAlignment="Left" Margin="6,26,0,0"
IsEditable="true"
VerticalAlignment="Top" Width="231"
IsDropDownOpen="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type Gui:BuildCommandWindow}}, Path=IsDropDownOpened }"
KeyUp="ComboBoxFunctionsKeyUp"
PreviewKeyUp="ComboBoxFunctionsPreviewKeyUp"
IsTextSearchEnabled="False" />

I styled an expander control. I then templated a ListView so that each ListViewItem is the expander.
The problem is that the expander doesn't fill up to the width of the list. It only appears as wide as the expander's content.
Ok, here's the XAML. I know it's alot but I thought you may want to copy & paste to see what it does. Can anyone see why the list items don't sie properly?

How would changing the height of the rows affect the width of the expanders in the list?

Hi, I am using WPF Toolkit Charting controls to create a bubble chart. I have been able to plot the bubble chart but now I need each bubble to be shown as a circle with sectors like in a piechart.
My first thought is to plot the piechart in a user control that would serve as a template for the bubble datapoints in the Bubble chart - if this is possible, i have no idea how to go about it.
So is there a way to customize the bubble Datapoints of the Bubble Series in this way or can someone tell me how i can achieve something like this.
Thanks in advance.

Did anyone knows the method to merge cells in C1Flexgrid for WPF not the usual DataGrid? I need to look my C1Flexgrid exactly like this,
Need to merge the cells and to give a back color to it. Please help me out.

You are posting a lot of questions here about a commercial third party control. When you purchased the control, you will also have purchased support for it - that would be the best place to start for getting expert help with the control. You might as well get your moneys worth.

Hello,
I am writing my app using MVVM pattern.
I have a XamDataGrid and i need to display in it my ViewModels.
I have a collection of VMs so each VM should be a row in the DataGrid.
Also each VM has a child VM that has collection of VMs. Each such VM contains 3 properties- Field, Value and operator.
I need the DataGrid to have dynamic fields according to the fields i have (in the collection of "small" VMs). each cell will contain the right value from the small VM under the right field .
The operator value should be displayed in another operator column. All operators are the same for the VMs related to same row in the DataGrid.
Currently i did it using dependency property- i bind the collection of VMs and than build a DataTable with dynamic columns and set is as DataSource of the dataGrid.
The thing is that it is fine if my DataGrid is read-only. But i need an option to change the DataGrid values . If i will do it with current code (with dependency property) i don't know what VM to change (because the DataGrid cell is not bind to any object).
How can i still solve this so it will work with binding?

|
|
|
|
Right,
But i don't know the number of fields i have.

Using C# only, and not WPF, is there a way to tie a TextBlock and TextBox together so that if I put them in a ListBox, they both scroll together? This is assuming you can put two controls in a ListBox, which you might not be able to do. If not, how can I do this. I have got working my scrolling List of TextBoxes, but I want to put a Label at the front of each TextBox. Either by a string or by a TextBlock.
But, I want to do this on the fly in C# and not use any WPF. If possible.

Not sure about the listbox control but I would assume it will take a data template which means you should use a template with a grid/stackpanel and a textblock bound to a description field and the other textblock/box bound to the value field in your list.
Don't give me any crap about not wanting to do it in xaml, if that is the case then go back to winforms where you are meant to manipulate the view.

Well said!

I don't use Winforms. And, I have my reasons for not wanting to do it in XAML.
|
|
|
|

I know you don't use winforms but the question goes against all the design principles of WPF. I'd be interested in the reasons for not wanting to use xaml.
I have found one and that is building a grid based on a pivot but there you don't know the number of columns.
