Unhandled exception when attempting to access grid definitio

26 Sep 2013, 18:00

What's happening:

[ 0] [0x1e221259] Noesis.dll!<Unknown function>
[ 1] [0x1e434ec4] Noesis.dll!<Unknown function>
[ 2] [0x0cd34f2c] <Unknown module>!<Unknown function>
[ 3] [0x09d59232] mono.dll!<Unknown function>
[ 4] [0x09e600b2] mono.dll!<Unknown function>
[ 5] [0x09d51d3d] mono.dll!<Unknown function>

The exact line of code invoking it:

IntPtr cPtr = NoesisGUI_PINVOKE.Collection_Get(swigCPtr, index);

Collections.cs line 62 while being called from:

Grid g = root.FindName<Grid>("MyGrid");
print(g.GetColumnDefinitions().Get((uint)1));

Where grid has 2 column definitions defined in xaml like so:

<Grid.ColumnDefinitions>
        <ColumnDefinition Width="*" />
        <ColumnDefinition Width="1"/>
    </Grid.ColumnDefinitions>

I've tried a few variations and all are causing problems.

My goal is to be able to modify a grid column width in code...

I tried this xaml:

<Grid
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="100"/>
    </Grid.ColumnDefinitions>
    
</Grid>

And the following script in Unity:

public class GridTest : MonoBehaviour
{
    void Start ()
    {
        NoesisGUIPanel gui = GetComponent<NoesisGUIPanel>();
        Grid root = gui.GetRoot<Grid>();

        ColumnDefinitionCollection columns = root.GetColumnDefinitions();
        if (columns != null)
        {
            uint numColumns = columns.Count();
            Debug.Log(System.String.Format("Num columns = {0}", numColumns));

            for (uint i = 0; i < numColumns; ++i)
            {
                ColumnDefinition col = columns.Get(i).As<ColumnDefinition>();
                GridLength width = col.GetWidth();
                Debug.Log(System.String.Format("Column {0} Width = {1} ({2})",
                    i, width.GetValue(), width.GetGridUnitType().ToString()));
            }
        }
        else
        {
            Debug.Log("Columns is null");
        }
    }
}

I get no errors with the previous example.
Could you please provide the exact xaml and code that is failing?

Problems with the bugtracker have been fixed.

Could you report this bug please?

Bwt, if you can attach a minidump file with the report, even better.

Thanks

I just found out the problem was not because of Noesis, I was attempting to get grid column definitions on the wrong grid, instead of the root grid which contained the grid column definitions I was trying to get the grid column definitions of one of its child grid columns.

Sorry about the mistake!
