I have datagrid (total records 7) and pagesize is 6 and pager style is numeric and two columns (name column and checkbox column and all are checked)

by default, currentpageindex is 0 and first 6 records appearing and clicked on 2nd page and it shows 7th record. when uncheck 7th checkbox(2nd page) and click on save button, saving user selection to Database and populating grid again.

now total record count is 6 and current pageindex should be 0. but it is not changing and pageindex remains 1 and I gotta error for this case.

"Invalid CurrentPageIndex value. It must be >= 0 and < the PageCount."

Can anybody help?

Thanks

Have you physically tried setting the PageIndex to 0? See if that clears up your error.

"The one language all programmers understand is profanity."

finally i ended up with following calculation/solution and is working good.


        If dtSelectedInstitutions.Rows.Count > 6 Then
            If dtSelectedInstitutions.Rows.Count / 6 > dgSI.CurrentPageIndex Then
                sPageIndex = dgSI.CurrentPageIndex - 1
                If sPageIndex = -1 Then dgSI.CurrentPageIndex = 0
            Else
                dgSI.CurrentPageIndex = dgSI.CurrentPageIndex - 1
            End If
        Else
            dgSI.CurrentPageIndex = 0
        End If

I had a similar problem with paging in a datagrid. My was due to changes in search criteria. It seems like dparsons idea should work. I tried working it out with IF statements and it didn't work in the long run. To fix it I had to clear the grid and reload it which also set the index back to zero.

Good luck.
