推荐答案

如果您的数据源没有数据，则根据数据表的行数显示消息.

在将数据源绑定到网格之前，请检查数据表中是否有行.如果有任何行，则将其绑定，否则显示消息.
例如:

If your datasource does not have data then show the message based on the datatable row count.

Before binding the datasource to grid, check for rows in the datatable. If there is any row then bind it or else show the message.
Ex:

// Sample snippet in C# - it was easy and quick for me to write
if(mygridsDataSourceTable.Rows.Count > 0)
{
  // BindGrid
}
else
{
  // Show message that there is no record. 
  // Show grid with Emptytextmessage
  // do whatever you like!
}
