ObjectDataSource does not find SelectCountMethod

Question

I am trying to use the ObjectDataSource with enabled paging. This requires me to use the SelectCountMethod (so the grid can know how many pages there are).

Accepted Answer

Your method does not take the same parameters because parameter names are case-sensitive:

```
public static int GetContentGridItemsCount(Guid? contentItemId,
    string contentTypeId, string contentTypeGroup,
    Guid? parentItemID, string parentFieldID)
{
}
```

Is not the same as:

```
public static int GetContentGridItemsCount(Guid? contentItemID,
    string contentTypeID, string contentTypeGroup,
    Guid? parentItemID, string parentFieldID)
{
}
```

The names of the first two arguments have to end with a uppercase `D` in order to match the method signature `ObjectDataSource` is looking for.
