Use the Background and AlternatingRowBackground properties.

Hi
Background and AlternativeRowBackground isn't good enough.
As I mentioned before , the color of each row shall be retreived from the model(stored in the database).
Also,there can be more than 2 users,and each user have it's own color.
Tanks for your help,
Eli

You will need to create a RowStyle for your DataGrid and bind the Background property to the ColourProperty on your class. Something like this:-
<DataGrid ItemsSource="{Binding Path=PostCollection}" AutoGenerateColumns="False">
<DataGrid.RowStyle>
<Style TargetType="DataGridRow">
<Setter Property="Background" Value="{Binding Path=RowColour}"/>
</Style>
</DataGrid.RowStyle>
<DataGrid.Columns>
<DataGridTextColumn Header="UserName" Binding="{Binding UserName}"/>
<DataGridTextColumn Header="Status" Binding="{Binding Status}"/>
</DataGrid.Columns>
</DataGrid>
This obviously assumes the colour property of your user class is called RowColour and that it returns a Brush type. If not you will need to provide a converter if your property returns a Color or string type.
Hope this helps

Once you get the hang of it, it becomes second nature, then you will be amazed at what you can accomplish with it.
Good luck.

I have been searching on the internet for a sample to show me how to show the sql server reporting services (SSRS) reports from a silverlight page i.e. (.xaml)
I have seen where an .aspx file should be used but there is no example on how to use the .aspx page inside or from the .xaml page.
Can you please let me know or point me to a simple site where I can see how to show my SSRS reports from my silverlight application?
Thanks

Thank you for the link which I had seen before.
What I would liek to find out is that in this link which you sent, where do I add the /RpDemoWebForm.aspx webform?
Is it added to the host which has a default.aspx or o the silverlight project?
Thanks

I have added mine in a folder in the web project (where the default.aspx lives. In that folder I have all the bits required to get the data and the .rdlc files with the viewer aspx

Hi All,
I have a stack panel which has grid to show footer buttons. This grid has some column definitions with some fixed width and with * as well. In Star columns I am having Grids again with some coulmn definitions in which I am placing the buttons. These columna are some fixed width, auto. In auto columns I am placing buttons.
My problem here is when I resizing and minimizing my browser some buttons are becoming invisible. It seems the columns are over written one another.
Is there any way that I can make the buttons stretch and make them not over written by the other columns?
Thanks for the help.

Can you post some simplified XAML that demonstrates your issue explicitly (so we don't have to guess what you mean exactly)?

Hi,
I got the fix for this problem, Grid columns over write on one another, the best way is to create the columns to fit all the elements in the column.

Hi,
I want to hide all the controls in a column in my WPF application.
Note - I dont want to hide column, I want to hide its contents only.
Please help me.

Where are the columns ? Are they on a DataGrid, ListView or normal Grid ?

Then I think that you are going to have to create a boolean property in your codebehind/viewmodel, and bind each control to this property. Then whenever you want to show or hide your controls you can just set the property accordingly.
Hope this helps

Thanks You very much . but i am new to wpf can you tell me how can i bind control to property.
|
|
|
|

You should do something like this:-
Fisrt of all create a Boolean property in your code behind that you can bind to(ensure your code file uses the INotifyProperty Interface[^] and your property setter raises the PropertyChanged event)
Then declare the Converter that will set your control's Visibility property to Hidden if your boolean property is true like this:
<Grid.Resources>
<BooleanToVisibilityConverter x:Key="HiddenConverter" />
</Grid.Resources>
Then in your XAML you bind the control's Visibility property to the boolean property, declaring the Converter property to use the HiddenConverter set up previously.
<Label Grid.Column="1" Content="Label1" Visibility="{Binding Path=ShowControls, Converter={StaticResource HiddenConverter}" Margin="3"/>
Then whenever you change the state of your boolean property, the control will be shown/hidden appropriately
Hope this helps

Why not just create a Visibility property? that way you don't need the converter... unless you are using the bool elsewhere, of course .

For my application I need to have different context menus for different text boxes. One of the features I wanted to add to the context menu was the ability to add words to a custom dictionary as the application will be used in a technical field where a lot of words won't be in a standard dictionary. I found a snippet of code online that showed how to do this, however it is in C# and uses a lambda expression that I'm having a very hard time converting. The specific line of code I'm having trouble with is this:
mnuAddToDictionary.Click += (object o, RoutedEventArgs rea) =>
{
this.AddToDictionary(this.txtEdit.SelectedText);
};
mnuAddToDictionary is a menu item and AddToDictionary is the method that actually does work of adding the selected misspelled word to the custom dictionary.
The AddToDictionary method is set up thus:
Public Sub AddToDictionary(ByVal entry as string)
End Sub
The closest I was able to get was AddHandler AddToDictionary.Click, AddressOf AddToDictionary, however I'm getting an error message because the delegate and the method do not have the same signature.
I pretty new to WPF and I'm not familiar with lambda expression yet because I never needed them. Any help would be greatly appreciated as I'm at a loss of what to do now. Any help would be greatly appreciated and thanks in advance.

The Click handler has to have a signature of object, RoutedEventArgs. You'd have to have an intermediate function with that signature that then calls your AddToDictionary function. Probably why they used a lambda . Vb.net supports lambdas too. I don't know vb.net very well, but I think the syntax is something like:
mnuAddToDictionary.Click = Sub(o, e)
AddToDictionary(txtEdit.SelectedText)
End Sub
Or you can just point it to an intermediate function as I said.
|
|
|
|

I was trying something along those lines however when I try to create the lambda expression I get this error message:
Public Event Click(sender As Object, e As System.Windows.RoutedEventArgs) is an event, and cannot be called directly. Use a
That's why I was trying to use the AddHandler method because I can't figure out how to hook into the Click event. I think the lambda expression is correct because I don't get any error messages (although I had to change the 'e' to 'rea' because the variable 'e' hides in an enclosing block.
I think I will go with the immediate function but if someone can explain how I can hook into the click event I would appreciate it since that seems to be a neater why to do it over using an intermediate function. Thanks!

Actually though I think there might be a problem with the intermediate function. I have several text boxes that have this custom context menu so I created a independent function. When you right-click on any of these text boxes, they call this function which know by the sender parameter which text box called it. In that function is where the AddToDictionary menu item is added. If I use AddHandle mnuAddToDictionary, AddressOf AddEntryToDictionary, then when the user clicks on 'Add To Dictionary' how does the AddEntryToDictionary method know which text box the context menu is being currently displayed on? I was thinking I could use a public variable to save the current text box, but I don't think that is a very efficient way.
|
|
|
|
|
Okay...so I finally figured out how to do it. It is actually a combination of the AddHandler method and a lambda expression. The line of code that worked was:
AddHandler AddToDictionary.Click, Sub()
AddEntryToDictionary(selectedText)
End Sub
Originally I was trying to use sender.SelectedText where sender was a ByRef parameter that was the text box that was calling this method, however ByRef parameters apparently can't be used in lambda expressions so I had to do add this line Dim selectedText As String = sender.SelectedText just before the AddHandler line.
Hope this helps others.
