Can someone assist me with the issue of my table crashing when there is data in the DataGrid in WPF? It appears that the DataGrid is creating its own column causing the problem.

There could be a number of different reasons why your table is crashing when there is data in the DataGrid in WPF. However, one possible cause of the problem could be due to the DataGrid creating its own column. Here are some steps you can take to troubleshoot the issue:

1. Check the DataGrid properties: Ensure that the AutoGenerateColumns property is set to “false”. This will prevent the DataGrid from generating its own columns.

2. Check the DataContext: Ensure that the DataContext of the DataGrid is set correctly. The DataContext should be set to an object that implements the IList interface.

3. Check the column definition: Ensure that the column definition in the XAML code of the DataGrid matches the type of data being displayed. For example, if you are displaying a datetime value, ensure that the column is defined as a DateTime column.

4. Check the binding: Ensure that the binding of the column is correct. Check that the binding expression for each column matches the correct property of the data item being displayed in that column.

5. Check if there are any exceptions: Check if there are any exceptions being thrown by the DataGrid control. If there are, these will give you an idea of what is causing the problem.

6. Try removing some columns: If the DataGrid is still crashing, try removing some columns to see if that helps.

7. Check the performance of the application: If the DataGrid is crashing due to performance issues, try optimizing the application. For example, you could implement paging to load only a small portion of the data at a time.

By following these steps, you should be able to identify and resolve the issue causing your table to crash when there is data in the DataGrid in WPF.
