推荐答案

在gridview的rowcommand事件中尝试以下代码

Try below code in your rowcommand event of gridview

protected void gridview1_RowCommand(object sender, GridViewCommandEventArgs e)

{

        int index = 0;

        index = Convert.ToInt32(e.CommandArgument.ToString());

        GridViewRow row = gridview1.Rows[index];



}

只需调用fillgrid函数，如下所示。

解决方案1 ​​

Just call the fillgrid function as follows .
Solution 1

FillGrid();
   grdView.PageIndex = e.NewPageIndex;
   grdView.DataBind();

解决方案2

在Page index中添加以下代码更改

Solution 2
Add the following code in Page index Changing

if (CustomersGridView.EditIndex != -1)
    {
      // Use the Cancel property to cancel the paging operation.
      e.Cancel = true;

      // Display an error message.
      int newPageNumber = e.NewPageIndex + 1;
      Message.Text = "Please update the record before moving to page " +
        newPageNumber.ToString() + ".";
    }
