When i have added
```
if (columns == null) {
return;
}
```
in DataGridLinesBeadForICollectionView then this same exception occurs in
DataGridColumnResizeBead then i added
```
if (columns == null) {
return;
}
```
in DataGridColumnResizeBead and then again this exception occurs in
DataGridLinesBeadForICollectionView but on other line then i added this again
there and exception gone.
