将数据添加到数据网格

Question

I am working on ac# project and I am having a really weird problem.

I'm reading in a file and processing the line and storing the results in separate variables within a list array. I am then going through the list array and populating it into the datagrid.

It successfully loading the file and its a creating a new row for line in the file but each line is blank and there are no columns being displayed. Below is a screenshot of how it looks.

When I debug it I can view the contents of the variables and all the text is there as expected. Below is the code I am using

private void loadNonVerbose(List<LogCatDetails> logCatDetailsList)
        {
            DataSet ds = new DataSet();
            DataTable table = new DataTable();
            DataColumn logLevel = new DataColumn("Log Level", typeof(string));
            DataColumn tag = new DataColumn("Tag", typeof(string));
            DataColumn processID = new DataColumn("Process ID", typeof(int));
            DataColumn message = new DataColumn("Message", typeof(string));

            table.Columns.Add(logLevel);
            table.Columns.Add(tag);
            table.Columns.Add(processID);
            table.Columns.Add(message);

            ds.Tables.Add(table);

            int i = 0;
            foreach (LogCatDetails logCatDetails in logCatDetailsList)
            {
                DataRow row = table.NewRow();
                row[logLevel] = logCatDetails.LogLevel.ToString();
                row[tag] = logCatDetails.Tag;
                row[processID] = logCatDetails.ProcessID;
                row[message] = logCatDetails.Message;
                table.Rows.Add(row);
                if (i == 10)
                {
                    break;
                }
                i++;
            }

            logCatDataGrid.ItemsSource = ds.Tables[0].DefaultView;
        }

Thanks for any help you can provide

UPDATE Below is how the datagrid is defined in the XML

<DataGrid ColumnWidth="*" AutoGenerateColumns="False" Margin="12,51,12,12" Name="logCatDataGrid" />

Answer 1

Set the AutoGenerateColumns property of the DataGrid to True :

<DataGrid ColumnWidth="*" AutoGenerateColumns="True" Margin="12,51,12,12" Name="logCatDataGrid" />

HighCore is correct, and I recommend you follow his guidance. The DataSet/DataTable s are unneeded. You could simplify this by simply modifying the code-behind to the following:

private void loadNonVerbose(List<LogCatDetails> logCatDetailsList)
{
    logCatDataGrid.ItemsSource = logCatDetailsList;
}
