PROBLEM

RadPageLayout throws IndexOutOfBounds exception when iterating over LayoutRowCollection.

DESCRIPTION

When I try to use a For Each loop to iterate over the LayoutRowCollection, I receive an IndexOutOfBounds error.

SOLUTION

The RadPageLayout component does not fully implement the GetEnumerator() method from the IEnumerable interface. As an result, an iterator can not be built automatically which leads to issues while using a For Each loop.

To work around this issue - a traditional For loop can be used. The code below demonstrates how to loop over all rows and columns of a RadPageLayout to do work or locate information.

C#

for (int row = 0; row <= RadpageLayout1.Rows.Count - 1; row++)
{
    for (int col = 0; col <= RadpageLayout1.Rows.Item(row).Columns.Count - 1; col++)
    {
        // Do Work
    }
}

VB

For row As Integer = 0 To RadpageLayout1.Rows.Count - 1
    For col As Integer = 0 To RadpageLayout1.Rows.Item(row).Columns.Count - 1
        'Do Work
    Next
Next
