gridview中具有分页和过滤的列的总和。 [英] Sum of a column in gridview with paging and filtering.

问题描述

decimal total = 0;
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        total += Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "calc"));
    }
    lblTotal.Text = total.ToString();
}

我的尝试：



我正在使用当前页面的总和（我正在使用分页和过滤）。我想要所有gridview的总和，当我过滤我的gridview时，我也希望更新。

What I have tried:

I am taking the sum of current page with this (I am using paging and filtering). I want all my gridview's sum and when I am filtering my gridview I want that updated too.
