Unable to cast object of type 'Spire.Doc.TableRow' to type

[SpireLMS]

Hi Team,

I'm getting error while assigning Paragraph.OwnerTextBody.Owner to section.
Please find the code below
Dim fieldParagraph As Paragraph = gridField.OwnerParagraph
Dim section As Section = fieldParagraph.OwnerTextBody.Owner // Getting Error Here(Unable to cast object of type 'Spire.Doc.TableRow' to type)

Document which contains nested tables.

Please let me know, If I missing anything.

Thank you in advance

Hi Muthukumar,

Thanks for your inquiry.

Based on your description and code, I speculate that in the current case, the document hierarchy is as follows:

Code: Select all

Document->Section->Body->Table->TableRow->TableCell->Paragraph

So fieldParagraph.OwnerTextBody is actually a cell object in the table.
If you need to get the current Section, you should refer to the following code:

Code: Select all

Dim tableCell As TableCell=fieldParagraph.OwnerTextBody
Dim tableRow As TableRow=tableCell .Owner
Dim table As Table=tableRow.Owner
Dim section As Section=table.OwnerTextBody.Owner

Of course, if there are more levels of nested tables in your document. Then the hierarchy will look like below. You need to look up correspondingly to get the Section.

Code: Select all

Document->Section->Body->Table->TableRow->TableCell->Table(2)->TableRow->TableCell->Table(3)->....->TableCell->Paragraph

Hope it can help you. If there is any other question, just feel free to contact us.

Hi Andy,

Thanks for your response

I have tried with your provided solution. But, Still I'm getting error like "Value of the 'Body' cannot be converted to 'TableCell'"
And also "Owner is not a member of Table Cell".

Please let me know, If I missing anything.

Thank you in advance.
