hi all ,
I have a file upload option which on click of upload button, the file will be updated to the Grid,
now my question is ,
the first time upload has to get into the grid without comparing any grid values(as there will be no values in grid)
then when i am uploading the file for the second time , it has to check in the grid whether the same file name is there in the grid , if there throw the error , else save it to the grid,
then all the grid rows has to updated in the sharepoint list,
how can i do this
