How to customize your own DataGrid

How to customize your own DataGrid

The following example shows how to customize the DataGrid, including how to bind a able to a DataGrid, and how to hide some columns in The DataGrid.
First, if you only set the DataSource attribute of the DataGrid to A able, the TableStyle of The DataGrid will be DefaultTableStyle, and its TableStyle. Count attribute will be zero. Therefore, if you want your DataGrid to have a different table style, you must add your own table style.
The following example sets the data source attribute of a DataGrid and declares a new DataGridTableStyle and four DataGridColumnStyles. This is because in _ periodData. tables [AccountingPeriodData. accountingPeriod_TABLE] has six fields, but I only want to display four, and the first one must be read-only. Of course, I want to change the Header Text of each field, so I use this function to implement it. Note: we cannot set HeaderText as a string constant. We should get it from the source file.
By the way, I declare four DataGridColumnStyle objects, but update them to DataGridTextBoxColumn, which means you can also update them to a DataGidBoolColumn. Of course you should know the reason. :-) // Initialize DataGrid when the form is opened.
Private void InitializeDataGrid ()
{
// Set the DataGrid's datasource to a DataTable
DtgPeriods. DataSource = _ periodData. Tables
[AccountingPeriodData. AccountingPeriod_TABLE];
     
// Create a DataGridTableStyle and set its MappingName is Accounting_TABLE
DataGridTableStyle mydtgTableStyle = new DataGridTableStyle ();
MydtgTableStyle. MappingName = AccountingPeriodData. AccountingPeriod_TABLE;
     
// Create maid, set their properties
