WPF datagrid empty row at bottom

📝 Title: Fixing the Pesky Empty Rows Issue in WPF DataGrid

💡 Introduction: Have you encountered the frustrating problem of seeing mysterious empty rows at the bottom of your WPF DataGrid? 😫 Don't worry, you're not alone! This common issue can be quite puzzling, but fear not - we've got you covered with some easy solutions to banish those pesky empty rows for good! In this blog post, we'll dive into the root cause of this problem and provide step-by-step instructions to fix it. Let's get started, fellow developers! 🚀

🔍 The Problem: The problem revolves around a situation where an empty row appears at the bottom of the DataGrid, and sometimes more empty rows are added after interacting with the buttons or checkboxes within the grid. This behavior can be quite baffling, but fear not, we've got something up our sleeves! 😉

⚙️ The Cause: The mysterious empty rows are typically caused by the way the DataGrid is bound to the underlying data source. In the provided context, the DataGrid is bound to a DataTable called GameData. However, the code snippet shared doesn't explicitly remove any previously added rows from the DataTable before returning it, leading to the accumulation of empty rows over time.

🛠️ The Solution: To fix this issue, we need to ensure that the DataTable returned by the GameData property does not contain any empty rows. Here's a step-by-step solution you can follow:

1. Update the property GameData with the following code:

public DataTable GameData
{
    get
    {
        DataSet ds = new DataSet();
        FileStream fs = new FileStream(IMDB.WebPage.Class.Config.XMLPath,
        FileMode.Open, FileAccess.Read);
        StreamReader reader = new StreamReader(fs, Encoding.Default);
        ds.ReadXml(reader);
        fs.Close();
        DataTable temp = ds.Tables[0];
        
        // Remove empty rows from the DataTable
        for (int i = temp.Rows.Count - 1; i >= 0; i--)
        {
            if (temp.Rows[i].RowState == DataRowState.Deleted ||
                temp.Rows[i].RowState == DataRowState.Detached ||
                temp.Rows[i].IsNull(0))
            {
                temp.Rows.RemoveAt(i);
            }
        }

        return temp;
     }
}

1. By looping through the rows of the DataTable, we check if a row is empty using the IsNull method. If a row is empty (all columns are null), we remove it from the DataTable using the RemoveAt method.

2. 🎉 Voila! You're done! Compile and run your application, and you should now be rid of those irritating empty rows. Your DataGrid will now display only the relevant data, sans any emptiness.
