Asp.net _ static method-convert a Grid to a able method

After the GridView is bound to a able, how does one obtain the value displayed after the GridView is bound? In the context required by the project, search for the method to retrieve the text displayed by cells, and then write a static method, after use in the project, the bug is fixed and relatively stable. Lele is better than zlele, And you can post the code for correction.
