Background code:

Protected   Void Btnshowexcel_click ( Object Sender, eventargs E)
{
Try
{
This . Fileupload1.saveas ( " D: \ temp \\ "   + Fileupload1.filename );
Dataset DS = LH. getexceldata (fileupload1.filename );
String Excelname = Fileupload1.filename;
Hiddenfield1.value = Excelname;
Gridview1.datasource = DS;
Gridview1.databind ();
Btnshowexcel. Enabled =   False ;
Btnaddexcel. Visible =   True ;
}
Catch
{
Response. Write ("<SCRIPT> alert ('check failed! Check whether the path is correct! '); </SCRIPT>");
}

}

Because you need to import data to the database in another button event, you can use the hiddenfield control to easily store a variable value.
This control is very handsome ~~~~~~~~
Shuang Shi Jie is doing image design next to me, think of "broken head ~~~~ Hey !!!
It's so happy to ask Lao Zhu for help if you have any problems.
Don't you have to worry about the issues above. I just want to decide when to get it ~~~~~~~~~

Really happy :)
