c# - Error: Deleted row information cannot be accessed through the row -


to whom may concern, have searched considerable amount of time, work way out of error

"deleted row information cannot accessed through row"

i understand once row has been deleted datatable cannot accessed in typical fashion , why getting error. big issue not sure desired result, outline below.

basically when row in "dg1" deleted row beneath takes place of deleted row (obviously) , inherits deleted rows index. purpose of method replace , reset rows index (via grabbing corresponding value in dataset) took deleted rows place , such index value.

right using label (lbltext) try , response process, crashes when last nested if statement trys compare values.

here code:

void dg1_click(object sender, eventargs e)     {         rowindex = dg1.currentrow.index; //gets current rows         string value = convert.tostring(dg1.rows[rowindex].cells[0].value);          if (ds.tables[0].rows[rowindex].rowstate.tostring() == "deleted")         {              (int = 0; < dg1.rows.count; i++)             {                  if (convert.tostring(ds.tables[0].rows[i][0].tostring()) == value)                  // ^ **where error occurring**                 {                     lbltest.text = "aha!";                     //when working, place index of compared dataset value                                   rowstate, displaying current index of row focussed on in 'dg1'                 }             }         }

thanks ahead of time help, did search, , if easy figure out through simple google search allow myself repeatably hate on me, because did try.

  • gc

the current value data column in inner if statement not available deleted rows. retrieve value deleted rows, specify want original value. should fix error:

if (convert.tostring(ds.tables[0].rows[i][0, datarowversion.original].tostring()) == value)
