datagrid|web| Cell thinking:
Adds a double-click event for each cell when the control is created and marks the row and column number of the cell.
When you double-click a cell, the row number of the cell and the column number are returned as parameters to the server.
The DataGrid is again bound to modify the value of the object cell.
Known problem: When the contents of a cell are enclosed in single quotes ('), the contents are not truncated. But this is not the case when you enter it later.
The tall man knows how to solve, please tell me.
