        if (totalPageSize % 10 == 0)
        {

        }

I have done this....

Here is the mistake:

C#

DataTable dt = article_list_class.getTotalArticles();
        totalrows = dt.Rows.Count;
        PAGEsize = 10;
        totalPageSize = totalrows / PAGEsize;
        if (totalPageSize % 10 == 0)
        {
            totalPageSize = Convert.ToInt32(totalPageSize);
        }
        else
        {
            totalPageSize = Convert.ToInt32(totalPageSize)+1;
        }

The problem is the integer division. It truncates, which is not what you want here. Try:

int totalrows = dt.Rows.Count;
int PAGEsize = 10;
int totalPageSize = (int)Math.Ceiling(totalrows * 1f / PAGEsize);

... or, if you want to do it with integer arithmetic only:

int totalrows = dt.Rows.Count;
int PAGEsize = 10;
int totalPageSize = (totalrows + PAGEsize - 1) / PAGEsize;

Solution 1

is your data is in gridview

common mistake
Instead of using Gridview.Rows.count you can use table.rows.count
here table is Gridview datasource table

thanks
