Ahh. Yes. I didn't quite understand that. I haven't done any Binding before, but looks pretty straightforward. I'm sure I can figure it out with your sample. I appreciate it.
I had actually created a ListBox and populated it with TextBlocks showing the Email #, but that's it. I couldn't figure out how to populate it with a second item TextBoxes. Binding looks like the answer.

It is really straightforward. I've no doubt you'll breeze through it.

Pete,
Stumped. I have the following Grid setup. 3 columns. Within Column 0, I have 5 rows. Within Column 0, Row 3, I have 2 more columns. It works. However, I can't get the 'EMAIL ADDRESSES' TextBlock to appear in Column 2. Even with Grid.Column = "0" Grid.Row = "2". Where does it need to be in the code? Also, if I want controls in Row 3, now I have a second Column constraint to deal with (Col 0, Row 3, Column 0 or 1). How do I deal with that? I tried naming the Grid, but it doesn't allow that type of syntax. I think that's only for C# code.
Sutton
<Grid Name="MiscGrid" ShowGridLines="True" Height="768" Width="1220">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="330"></ColumnDefinition>
<ColumnDefinition Width="700"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Grid Grid.Column="0" Name="C0Grid" ShowGridLines="True">
<Grid.RowDefinitions>
<RowDefinition Height="120"></RowDefinition>
<RowDefinition Height="180"></RowDefinition>
<RowDefinition Height="30"></RowDefinition>
<RowDefinition Height="300"></RowDefinition>
<RowDefinition Height="*"></RowDefinition>
</Grid.RowDefinitions>
<Grid Grid.Row="3" Name="R2Grid" ShowGridLines="True">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="60"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<TextBlock Height="20" HorizontalAlignment="Left" Margin="0,0,0,0" Text="EMAIL ADDRESSES" VerticalAlignment="Top" FontSize="16" />
</Grid>
</Grid>
</Grid>

Try putting Grid.Column="1" into the TextBlock, as the count is zero based. But, I think you are getting a bit confused as to how your grid looks. Reading through your Grid code, I get the following visualisation:
-----------------------------------------------------
| | | |
|---------------| | |
| | | |
|---------------| | |
| | | |
|---------------| | |
| | EA | | |
|---------------| | |
| | | |
|---------------|-----------------|-----------------| EA represents the Email Addresses textblock. Try setting each Grid Background to a different colour, and you'll see what I mean.

You are correct. That's what it looks like, except not to scale. I have this test code running in Visual C#. I wanted to put the 'EMAIL ADDRESSES' TextBlock in Row 2 as a header. But, I figured it out. You have to put the TextBlock code BEFORE the redefinition of the Row 3 Grid. That actually makes sense. I'm guessing Row 2 is out of scope once Row 3 is redefined into 2 columns.
BTW, I come from the embedded world of 25+ years, but not much Windows programming. I'm just dangerous enough to get a basic software app working in Visual C#. But, with fairly basic controls. I'm now trying to enhance the app with a few more complex controls.
Thanks for your advice.

Pete,
I took a different approach. I'm trying to create a ListBox on the fly without using any XAML code. I got it working - almost. What I have is an array of TextBoxes of 'Zone Descriptions'. I can put those into the ListBox as ListBoxItems, and it works great - no problem.
I want to add at the front of the TextBox a TextBlock or header that says 'Zone 1' or whatever the zone is along with the TextBox, which is user changeable. I have an array of TextBlocks. But, I can't (or don't know how to) adjust the ListBoxItem.Content to hold both the TextBlock and TextBox combo. LBI[i].Content = TBlkZoneDesc[i] + TBxZoneDesc[i] is what I want to do, but that syntax is not allowed. Doing either one separately works fine, but not both.
Do you have a suggestion on how to do that?
Sutton
ListBox LBZoneDesc = new ListBox();
LBZoneDesc.Width = 300;
LBZoneDesc.Height = 240;
Grid.SetColumn(LBZoneDesc,0);
Grid.SetRow(LBZoneDesc,2);
ListBoxItem[] LBI = new ListBoxItem[64];
for (byte i = 0; i < 5; i++)
{
LBI[i] = new ListBoxItem();
LBI[i].Padding = new Thickness(2);
LBI[i].Content = TBxZoneDesc[i];
LBZoneDesc.Items.Add(LBI[i]);
}
C0Grid.Children.Add(LBZoneDesc);

Hi
I needed a custom ComboBox control with a DataGrid as popup. I managed to change the MSDN example and everything works except I can't set ComboBox.IsDropDownOpen property from the
Trigger.
It it usefull also for setting ComboBox.Text property with the text selected from the DataGrid.
The problem is at the end near comments:
Property="ComboBox.IsDropDownOpen" Value="False"
(this line does not have any affect because the comboBox is not identified by name or style type).
Somehow I need to specify the comboBox style..
Any ideas how to do it?
RelativeSource with TemplateParent..

Hi there, I have this XML file:
="1.0"="utf-8"
<Wpf>
<wpfctrl id="NavBtnTemplate">#FFCFDEFF</wpfctrl>
</Wpf>
and i want to bind Fill property of My Rectangle to value of wpfctrl node with id="NavBtnTemplate". How I can achieve this? Actually I have this rectangle inside my custom UserControl's Control Template. But hope that will not be the problem since I can bind to the properties of elements inside UserControl:
My UserControl (actually is very simple)
<UserControl.Resources>
<ControlTemplate x:Key="WpfWebSparkNavTemplate" TargetType="{x:Type Button}">
<Grid x:Name="controlLayout" Height="29.648" Width="84.284">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal"/>
<VisualState x:Name="MouseOver"/>
<VisualState x:Name="Pressed"/>
<VisualState x:Name="Disabled"/>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Rectangle x:Name="rectangle"Fill="#FFCFDEFF" Margin="0" Height="31" d:LayoutOverrides="VerticalAlignment" >
</Rectangle>
<Label x:Name="buttonCaption" VerticalAlignment = "Center"
HorizontalAlignment = "Center"
FontWeight = "Bold" FontSize = "12" Content="{TemplateBinding Content}"/>
</Grid>
</ControlTemplate>
</UserControl.Resources<UserControl.Resources>
<ControlTemplate x:Key="WpfWebSparkNavTemplate" TargetType="{x:Type Button}">
<Grid x:Name="controlLayout" Height="29.648" Width="84.284">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal"/>
<VisualState x:Name="MouseOver"/>
<VisualState x:Name="Pressed"/>
<VisualState x:Name="Disabled"/>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Rectangle x:Name="rectangle"Fill="#FFCFDEFF" Margin="0" Height="31" d:LayoutOverrides="VerticalAlignment" >
</Rectangle>
<Label x:Name="buttonCaption" VerticalAlignment = "Center"
HorizontalAlignment = "Center"
FontWeight = "Bold" FontSize = "12" Content="{TemplateBinding Content}"/>
</Grid>
</ControlTemplate>
</UserControl.Resources>

I did not found Blend wizard to allow me to state such filters on XML
Please help. Thank you.

I have a grid with 3 defined columns. Is there a way to divide column 1 into 3 grid rows without affecting the other 2 columns? I've tried defining RowDefinitions, but it spans all 3 columns. I don't want that. I only want it to affect the 1 column.
|
|
|
|
|
Embed another Grid inside the first column, and put the RowDefinitions in that Grid.
|
|
|
|
|
Thanks. But, I'm not sure where to put it. I've tried before, and I get 'ColumnDefinition does not support direct content'.
<grid name="TestGrid" showgridlines="True" height="768" width="1220">
<grid.columndefinitions>
<columndefinition
="" width="330">
<grid name="C1Grid" showgridlines="True">
<grid.rowdefinitions>
<rowdefinition height="200">
<columndefinition width="700">
<columndefinition width="*">
|
|
|
|
|
I tried to put in my code, but it kicks it out.
|
|
|
|
|
<grid name="TestGrid" showgridlines="True" height="768" width="1220">
<grid.columndefinitions>
<columndefinition
="" width="330">
<grid name="C1Grid" showgridlines="True">
<grid.rowdefinitions>
<rowdefinition height="200">
<columndefinition width="700">
<columndefinition width="*">
|
|

|

You need to encode XAML in pre blocks for me to be able to see it. All I see there is empty space.
|
|
|
|
|
<Grid Name="TestGrid" ShowGridLines="True" Height="768" Width="1220">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="330">
<Grid Name="C1Grid" ShowGridLines="True">
<Grid.RowDefinitions>
<RowDefinition Height="200"></RowDefinition>
</Grid.RowDefinitions>
</Grid>
</ColumnDefinition>
<ColumnDefinition Width="700"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
</Grid>
|
|
|
|
|
What you need to do is:
<Grid Name="TestGrid" ShowGridLines="True" Height="768" Width="1220">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="330" />
<ColumnDefinition Width="700"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Grid Grid.Column="0" Name="C1Grid" ShowGridLines="True" />
<Grid.RowDefinitions>
<RowDefinition Height="200" />
<RowDefinition Height="250" />
<RowDefinition />
</Grid.RowDefinitions>
</Grid.ColumnDefinitions>
</Grid>You can now add your items to the Grid in Column 0 as you desire.

|
|
|

Thanks. However, when I execute this code, the 2 rows in column 0 span thru column 1 and column 2. That seems to mess up columns 1 and 2, since I have 2 full UI columns in 1 and 2. I need the grid to stop and column 1.
|

|

Pete,
Thanks. I got it. There was a missing Grid tag and one too many Column definitions.
Next question. If I have the following Grid (which is the same), why doesn't putting TextBlocks in Row 2 work? It always puts the two text blocks in Row 0, no matter what value I put in Grid.Row. Putting the Text in Grid.Columns 0,1, or 2 works fine. But, not the rows.
<Grid Name="MiscGrid" ShowGridLines="True" Height="768" Width="1220">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="330"></ColumnDefinition>
<ColumnDefinition Width="700"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Grid Grid.Column="0" Name="C1Grid" ShowGridLines="True">
<Grid.RowDefinitions>
<RowDefinition Height="120"></RowDefinition>
<RowDefinition Height="180"></RowDefinition>
<RowDefinition Height="330"></RowDefinition>
<RowDefinition Height="*"></RowDefinition>
</Grid.RowDefinitions>
</Grid>
<TextBlock Grid.Row="2" Height="20" HorizontalAlignment="Left" Margin="0,0,0,0" Text="ZONE DESCRIPTIONS" VerticalAlignment="Top" FontSize="16" />
<TextBlock Grid.Row="3" Height="15" HorizontalAlignment="Left" Margin="0,0,0,0" Text="(25 chars max)" VerticalAlignment="Top" />
</Grid>
|
|
|
|
|
That's because you've put your TextBlock elements in the outer Grid. You need to put them in the inner Grid for it to lay out using that Grid positioning.
|
|
|
|
|
Well, that was a duh moment. Thanks for the info. Works perfectly now.

No problem. Any developer who says they don't have a Duh moment is a liar. I have several a week.
