I am trying to set the grids LayoutObject.text and get the exception "One of the identified items was in an invalid format." when I assign to the

iGridOfData.LayoutObject.Text = robotGridLayout;

If I inspect the value of iGridOfData.LayoutObject.Text and robotGridLayout they both contain the same. They contain the following

"<iGridLayout>
<Col Index=\"-1\">
<Order>-1</Order>
<Visible>True</Visible>
<Width>64</Width>

</Col>
</iGridLayout>"

I have also

System.Xml.XmlDocument myDoc = new System.Xml.XmlDocument();
myDoc.LoadXml(z_JCD.robotGridLayout);

and no fault reported.

Any ideas?

Need a sample to reproduce the problem.

The cause of the problem seems to be when I set the layout explicitly and then try and use the .Text property

iGLayoutFlags layoutFlags = iGLayoutFlags.ColOrder | iGLayoutFlags.ColVisibility | iGLayoutFlags.ColWidth | iGLayoutFlags.Sorting | iGLayoutFlags.Grouping
iGridOfData.LayoutObject.Flags = layoutFlags;

with the iGLayoutFlags.Grouping and iGridOfData.LayoutObject.Text = <previous_values> there is the exception.

Solution was to remove the iGLayoutFlags.Grouping
