Re: Unknown Error - WPF Discussion Boards

I have a WPF form with a gridsplitter. The cursor is set to SizeWE, but it does not show the resize cursor on a mouseover. I can use it for resizing, so the control can grab the mouse.
Has anyone seen this problem? Any ideas?

Hi,
I have exactly the same problem.
here is my complete code:

<Grid Background="SteelBlue" x:Name="mainGrid">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="250"/>
        <ColumnDefinition Width="2*" />
        <ColumnDefinition Width="250" />
    </Grid.ColumnDefinitions>

    <Grid.RowDefinitions>
        <RowDefinition />
        <RowDefinition Height="25" />
    </Grid.RowDefinitions>

    <Border BorderThickness="4" BorderBrush="SteelBlue"  Background="White">
        <WFDesigner:WorkflowListView x:Name="WorkflowList" Margin="10"/>
    </Border>

    <WFDesigner:WorkflowDetailView x:Name="WorkflowDetail" Margin="0,4" Grid.Column="1" Background="White"/>

    <GridSplitter HorizontalAlignment="Right" Grid.Column="1" ResizeBehavior="CurrentAndNext" Width="4" Background="Red" />

    <Border BorderThickness="0,4,4,4" BorderBrush="SteelBlue"  Grid.Column="2" Background="White">
        <Grid x:Name="ToolboxProperties" DockPanel.Dock="Right">
            <Grid.RowDefinitions>
                <RowDefinition Height="2*" />
                <RowDefinition Height="1*" />
            </Grid.RowDefinitions>
            <ContentControl Content="{Binding ToolboxControl}"/>
            <ContentControl DataContext="{Binding SelectedItem}" Content="{Binding Designer.PropertyInspectorView}" Grid.Row="1"/>
        </Grid>
    </Border>

    <StatusBar Grid.Row="1" Grid.ColumnSpan="3" >
        <TextBlock Text="{Binding Status}" Margin="5,0" />
    </StatusBar>
</Grid>

I tried overriding it by setting "Cursor" value in the GridSplitter XAML definition but it didn't work.

Any idea?

Hi, This is what I do

<GridSplitter Grid.Column="0" ResizeDirection="Columns" Background="LightGray" Width="5" MouseEnter="GridSplitter_MouseEnter" MouseLeave="GridSplitter_MouseLeave"/>

private void GridSplitter_MouseEnter(object sender, MouseEventArgs e)
      {
          if (this.Cursor != Cursors.Wait)
              Mouse.OverrideCursor = Cursors.SizeWE;
      }

      private void GridSplitter_MouseLeave(object sender, MouseEventArgs e)
      {
          if (this.Cursor != Cursors.Wait)
              Mouse.OverrideCursor = Cursors.Arrow;
      }

I first check if the mouse is already in Waiting mode, as I dont want the users to be able to resize the app while I am doing some other stuff.

Hope it helps

hi,
try to set the cursor directly to the gridspliter.
you can do this in you constructor
mygridSpliter.Cursor = Cursors.SizeWE;

Setting the splitter cursor does not seem to work either. My code from the mouseEnter event.

private void GridSplitter_MouseEnter(object sender, MouseEventArgs e)
{
GridSplitter gridSplitter = sender as GridSplitter;

if (gridSplitter.Name == "Splitter1")
{
Splitter1.Cursor = Cursors.SizeWE;
}

}

Good Morning All

After my ouputed(DeepZoom)project, i open my Project in VS2008 and buit the Project and i got this Error. Google did not help.

Vuyiswa Maseko,

Few companies that installed computers to reduce the employment of clerks have realized their expectations.... They now need more and more expensive clerks even though they call them "Developers" or "Programmers."

Some days ago, I was working Expression Blend 2 and VS2008 SP1 and I got the same error .
I've reinstalled .Net Framework (3.5 SP1), and my problem has solved.

Thanks for your reply. I have a Problem Sometimes understanding Versions. I have tried to get rid of Beta Silverlight staff installed on my machine. Can you please tell me the Difference between 3.5 SP1 and 3.5, Can you please send me a link where i can download the Setup for offline Installation.

Thanks

No. You don't need Express edition if you already have VS 2008 professional or other edition. Are you still having that problem ??

Hi,

I am currently working on a SilverLight application that uses a WCF service to create and populate an Excel file and return the Result as the path on the server where the excel file is saved. This returned path will be used by the user to download/save the file.

I initially tried using the 'HypeLinkButton' and assigning the returned URL to the 'NavigateUri' property of the hyperlink. It did not work as when I clicked the URL, the page got navigated to a blank page and the error on the page was the following:

Error:
ManagedRuntimeError error #4004.
UnauthorisedAccessException Access is denied

Once I faced this issue as an alternative I tried navigating to a aspx page by opening a new window and specifying the window's URL as the returned file path. I couldnot find much on this online as well.

Any suggestions?

I do something like this to open a browser window when clicking on something. May not be exactly what you need, but perhaps can get you headed in right direction.

string redirectLink = "http://www.somedomain.com/some.xls"
string browserWindowOptions = "resizable=1|scrollbars=1|menubar=1|status=1|toolbar=1|titlebar=1|width=1000|height=725|left=5|top=5"

HtmlPage.Window.Navigate(new Uri(redirectLink), "_blank", browserWindowOptions)

So...I've been looking for WF threads to see what kinds of questions ppl have been asking, and what the solutions were. I dug through like 10 pages or so of WPF questions and finally gave up. Could we split off the WF and WCF forums so that the questions don't get drowned in the deluge of WPF?

Thanks.
