There is no SetRow() method on my Grid object.
<grid x:name="Grille" background="White" xmlns:x="#unknown">
I'm using Silverlight 2.0, without other plugins.
There is a SetValue() method (SetValue(DependencyProperty dp, object value)). It deals about System.Windows.DependencyObject. Would it be useful for my problem ?

Oops....sorry 
Grid.SetRow(bouton_new, rowvalue);

Thanks 
1) But if there is more than one Grid on the application, how to set which Grid ?
2) Second question, is it possible to insert a row ?
3) Is it possible to merge cells, like in HTML Tables ?

Which grid the property applies to is based on the element you pass to
SetRow() - the element's "parent" grid.

It should be the same as inserting a column as Colin showed in his reply.

I don't know what you mean since I don't know HTML
An element can span multiple rows and/or columns of a grid.
You'd use the SetRowSpan()/SetColumnSpan() methods to adjust that from code
(the default is 1).

Thank you a lot for your help, it's really more clear than before.
There is just again a misunderstood point :
>> Is it possible to insert a row ?
> It should be the same as inserting a column as Colin showed in his reply.
> myGrid.ColumnDefinitions.Add(new ColumnDefintion);
myGrid.ColumnDefinitions.Insert(1, col_def);
That is inserting a column definition amongs others, but do not move the following columns. It seems that columns are statically positionned, as there have a property like Grid.Column="2".
So is it really possible to insert columns and rows ?
I wish I am wrong !

It's up to you to place the row/column definitions where you want them.
If you insert a column/row dynamically then you may need to adjust the properties of the
child elements so they shift to the new column/row positions.
This can all be done programatically.
What are you trying to do that's not working?

Okay, I agree I could do it myself. I was just surprised it wasn't already in place.
But I found a component that does it :
http://www.vectorlight.net/controls/table.aspx
It's an extension to the Grid component.
It's nearly usable except a little bug.

How can i make a control of AUTO FIT(FIT TO SCREEN) in WPF just like we have in Microsoft Visual
Studio 2008,when we design a WPF page in visual studio.
See when we open a XAML page in design view in Visual Studio 2008,we get slider for zoom in and zoom out and also a FIT TO SCREEN button in it.I want to design this FIT TO SCREEN in my application also,but i'm not able to get required parameters.And i'm designing the application in WPF with C# as back end.So what should be the code for that.

Can you provide a little more detail in your question. I am not sure what you are asking.
|
|
|
|
|
i think you can use anchor.
|
|
|
|
|
Could you elaborate on how Anchor can be used.

Hi
I am VERY new to Silverlight and I am currently developing my first Silverlight Application. I have a bunch of mp3s located in my ASP.Net web app at "~/music/". And I have XAML as:-
<MediaElement x:Name="meAudioPlayer" AutoPlay="False" Source="music/test.mp3"></MediaElement>
But the mp3 doesn't play. If I copy the mp3 to "~/ClientBin/music/test.mp3" it works! But I can't copy ALL mp3s to the ClientBin folder. My web app has 1000s of mp3s located in the "~/music/" folder instead. The MSDN documentaton says that I can use Javascript APIs to set the source relative to the calling HTML page. But it doesn't have any example code. Could someone please show me how to do this?
Thanks!

I think it's because of wrong path... you need to go like ../music/test.mp3. or try to get full path from server-side playlist..

Now that you have been using WPF for a while, look back and tell me what your 'ah-ha' moment was...
Usually we have one defining point where all the pistons start firing and all the lights come on that opens up a whole new world for us. What was yours with regards to this technology?
|
|
|
|
|
Well - this[^] article describes mine. However, talking to Josh, Sacha, Dr WPF and Karl's been good for lots and lots of "oh wow" moments.
|
|
|
|
|
Not sure ALL the pistons are firing yet!
I liked this article on how a humble listbox can be completely changed in appearance.
http://bea.stollnitz.com/blog/?p=40[^]
Then going back a few weeks later and understanding (most of) the code this time.
Also as Pete said lots of good WPF authors here on CP.
Same thing, might not quite understand them, but let them sink in and they make more sense on rereading.
Another thing was understanding that XAML is not some mysterious language but you can do things like just make an arraylist with integers and bind it to a listbox, very easily when you know how.
The Pro WPF book has a nice chapter on this at the start. (You might be able to find this on google books, if you don't have a copy)
<window.resources>
<sys2:arraylist x:key="myArrayList" xmlns:x="#unknown" xmlns:sys2="#unknown">
<sys:int32 xmlns:sys="#unknown">1
<sys:int32>2
<sys:int32>3
</sys:int32></sys:int32></sys:int32></sys2:arraylist>
</window.resources>
<listbox itemssource="{StaticResource myArrayList" />
Then once you learn all that WPF stuff, you goto Silverlight and find out half of the good stuff is missing. *sob*

When I realized updating/expanding my old MFC-based UI code was taking way to
much time and I thought "hmm....I'll take a look at WPF...". 
I have Silverlight/WPF ah=ha moments several times a day...

Ooh, another one.
I was looking at my first attempt at a WPF app, and I was thinking "Who wrote this crap? It's all done wrong!"
Stuff like updating text on controls via a loop instead of just using databinding.
|
|
|
|
|
There have been many! And many followed by a ... "oh ... I didn't expect that" but mostly "doh!", "FECK" & "Blurgh!!"

I am really hoping someone here can help me. I've been playing around with the WPF DataGrid and am having a weird problem. What I have is a TabControl with two tabs. Each tab has a DataGrid with two columns. The first column Width is "Auto" and the second column Width is "*" which should fill the remaining space in the Datagrid. What is happening is that the DataGrid in the first tab's columns are sized appropriately, but the second tab's second column is wider than it should be. Also, if I change the SelectedIndex to the second tab, it's columns are size correctly but the first tab's columns aren't. I have tried to Invalidate the DataGrid control when the selected tab changes but that didn't seem to do anything. I'm not sure how to explain this better but here is some example XAML:
<TabControl TabStripPlacement="Left"
Margin="0,0,0,0"
Background="White" Padding="0,-10,0,0"
SelectedIndex="0"
Grid.Row="1"
x:Name="TabEdit">
<TabItem Header="Tab 1">
<tk:DataGrid
AutoGenerateColumns="False"
ItemsSource="{Binding Path=Properties}"
>
<tk:DataGrid.Columns>
<tk:DataGridTextColumn
Width="Auto"
IsReadOnly="True"
Header="Property"
Binding="{Binding DisplayName}"
/>
<tk:DataGridTextColumn
Width="*"
IsReadOnly="False"
Header="Value"
Binding="{Binding AggValue, NotifyOnValidationError=True, ValidatesOnDataErrors=True}"
/>
</tk:DataGrid.Columns>
</tk:DataGrid>
</TabItem>
<TabItem Header="Tab 2">
<tk:DataGrid
AutoGenerateColumns="False"
ItemsSource="{Binding Path=Properties}"
>
<tk:DataGrid.Columns>
<tk:DataGridTextColumn
Width="Auto"
IsReadOnly="True"
Header="Property"
Binding="{Binding DisplayName}"/>
<tk:DataGridTextColumn
Width="*"
IsReadOnly="False"
Header="Value"
Binding="{Binding AggValue, NotifyOnValidationError=True, ValidatesOnDataErrors=True}"
/>
</tk:DataGrid.Columns>
</tk:DataGrid>
</TabItem>
</TabControl>
If this is not enough information, I'd be happy to answer questions.
Thanks for reading!
P.S. Sorry if the code is hard to read. I couldn't get it to work in a code block (<pre></pre>)

Great! Thanks for trying it. I'm glad it's not something really obvious that I missed at least.
