I'm getting this error "index was outside the bounds of the array". Here my code

VB

Dim totalcolumn As Integer
If grdTraining.Columns.Count > totalcount Then
   totalcolumn = grdTraining.Columns.Count - totalcount
   For i As Integer = 0 To totalcolumn
      Dim field1 As HyperLinkField = DirectCast(Me.grdTraining.Columns(j), HyperLinkField)
      field1.DataTextField = ColumnsArray(i)
      Me.grdTraining.Columns(j).Visible = False
      j = j + 1
   Next
End If
BindGridView(grdTraining, dtTrainings)

FOR loop with i but inside you are increment j, where you define j? and what is the initial value?

thanks for your answer,j initialized before in my code ,J starts with value 6,when j=12 and i=6 i'm getting code break

Does your grdTraining has 21 columns? Also, commonly you go from 0 to columnCount-1...because of zero index start, your last column will have index one less than columnCount.

grdTraining columns is 15

One of the easiest bugs to resolve. Put a breakpoint at the start of the block and step line-by-line until you find exactly where it fails. Check all values. In the code above there are couple of potential culprits:
grdTraining.Columns(j), ColumnsArray(i) - you're not showing ColumnsArray or j initialiation so its hard to say for sure. Learn to debug, this is not forum question material as it is very easy to resolve.

No, don't go step by step. Just run it, the application will stop at exception (if exception options are correctly set up, which is the case by default). Then put a break point one line before this point, repeat, proceed by steps.

At beak point ,J starts with value 6,when j=12 and i=6 i'm getting code break

Excellent. Now walk through the code and find out which of the arrays runs out of indices. How many elements are there in ColumnsArray? How many columns the gridview has?

Solution 1

debug your code line by line and try to rectified the problem,try to find which array runs out of indices.
Check how many columns in column array and how many columns gridview really has. :)

You are suggesting him so please use comment for this.

upendra shahi 8-Apr-15 6:26am

I'm suggesting him because at-least he should try to do hard work for his issue.

Sergey Alexandrovich Kryukov 8-Apr-15 10:46am

Agree. Please see my other comment to this answer. Anyway, the vote of 1 someone gave you was hardly fair, I up-voted it.

thanx sir..

I think this advice is still acceptable as an answer, maybe not detailed enough, but really leading the inquirer for some resolution. Give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime.

Doesn't it make sense?
