单击编辑按钮时，如何在不向上滚动的情况下继续编辑一行？

Question

我正在一个 ASP.NET 项目中使用 C# 编写一个空的 Web 应用程序，我制作了一个带有 CRUD 操作的 gridview。但是当我执行我的项目并单击我制作的按钮时，它会将我带到第一行，然后我必须再次向下滚动。这真的很烦人，但我不知道为什么会这样。即使我使用了 MaintainScrollPositionOnPostBack="true" 它也不起作用。有什么我要添加到我的代码或我必须注意的东西吗？

Answer 1

谢谢你的解释。请在填充 gridview 之前尝试设置 gridview editindex（在更新和删除之后）希望这有帮助。在我的代码下工作。

protected void gvTestUsers_RowUpdating(object sender, GridViewUpdateEventArgs e)
{

    try
    {
        //Parameters Set From Grid
        string tmpUsers_key = (gvTestUsers.Rows[e.RowIndex].FindControl("txtID") as TextBox).Text.Trim();
        string tmpName = (gvTestUsers.Rows[e.RowIndex].FindControl("txtName") as TextBox).Text.Trim();
        string tmpCostCenter = (gvTestUsers.Rows[e.RowIndex].FindControl("txtCostCenter") as TextBox).Text.Trim();
        string tmpEmployee = (gvTestUsers.Rows[e.RowIndex].FindControl("txtEmployee") as TextBox).Text.Trim();
        string tmpFootPlate = (gvTestUsers.Rows[e.RowIndex].FindControl("txtFootPlate") as TextBox).Text.Trim();
        string tmpWirstCord = (gvTestUsers.Rows[e.RowIndex].FindControl("txtWirstCord") as TextBox).Text.Trim();
        string tmpExcluded = (gvTestUsers.Rows[e.RowIndex].FindControl("txtExcluded") as TextBox).Text.Trim();
        string tmpComment = (gvTestUsers.Rows[e.RowIndex].FindControl("txtComment") as TextBox).Text.Trim();
        string tmpsMsg = "";

        //Call function for SP_UPDATE
      bool FuncResult = fcEditTBL_USERS(Convert.ToInt32(tmpUsers_key), tmpName, tmpCostCenter, tmpEmployee, tmpFootPlate, tmpWirstCord, tmpExcluded, tmpComment, ref tmpsMsg, "Update");

        //add this 
        gvTestUsers.EditIndex = -1;
        PopulateGridView();

        lblSuccessMessage.Text = "Selected Record Updated.";
        lblErrorMessage.Text = "";
    }
    catch (Exception ex)
    {
        lblSuccessMessage.Text = "";
        lblErrorMessage.Text = ex.Message;
    }
}

并删除下面的行，

protected void gvTestUsers_RowDeleting(object sender, GridViewDeleteEventArgs e)

{

    try
    {

        {


            gvTestUsers.EditIndex = e.RowIndex;
            PopulateGridView();


            //Parameters for delete operation
            string dltUsers_key = (gvTestUsers.Rows[e.RowIndex].FindControl("txtID") as TextBox).Text.Trim();
            string dltName = (gvTestUsers.Rows[e.RowIndex].FindControl("txtName") as TextBox).Text.Trim();
            string dltCostCenter = (gvTestUsers.Rows[e.RowIndex].FindControl("txtCostCenter") as TextBox).Text.Trim();
            string dltEmployee = (gvTestUsers.Rows[e.RowIndex].FindControl("txtEmployee") as TextBox).Text.Trim();
            string dltFootPlate = (gvTestUsers.Rows[e.RowIndex].FindControl("txtFootPlate") as TextBox).Text.Trim();
            string dltWirstCord = (gvTestUsers.Rows[e.RowIndex].FindControl("txtWirstCord") as TextBox).Text.Trim();
            string dltExcluded = (gvTestUsers.Rows[e.RowIndex].FindControl("txtExcluded") as TextBox).Text.Trim();
            string dltComment = (gvTestUsers.Rows[e.RowIndex].FindControl("txtComment") as TextBox).Text.Trim();
            string dltsMsg = "";


            //Call function for SP_Delete
           bool FuncDelete = fcEditTBL_USERS(Convert.ToInt32(dltUsers_key), dltName, dltCostCenter, dltEmployee, dltFootPlate, dltWirstCord,dltExcluded, dltComment, ref dltsMsg, "Delete");

            if (FuncDelete == false)
            {
                lblErrorMessage.Text = dltsMsg;
                lblSuccessMessage.Text = " ";
                return;
            }


            gvTestUsers.EditIndex = -1;
            PopulateGridView();
            lblSuccessMessage.Text = "Selected Record Deleted.";
            lblErrorMessage.Text = "";

        }
    }
    catch (Exception ex)
    {
        lblSuccessMessage.Text = "";
        lblErrorMessage.Text = ex.Message;
    }
}

Answer 2

我通过将 SearchBox-Event 代码移动到我的 PopulateGridView 中解决了这个问题。所以现在 PopulateGridView 看起来像这样：

void PopulateGridView()
        {
            string find = "select * from TBL_USERS where (Name like '%' + @Name + '%') or (employee like '%' + @Employee + '%')";
            SqlCommand comm = new SqlCommand(find, con);
            comm.Parameters.Add("@Name", SqlDbType.VarChar, 255).Value = TextBox1.Text;
            comm.Parameters.Add("@Employee", SqlDbType.VarChar, 32).Value = TextBox1.Text;
            con.Open();
            comm.ExecuteNonQuery();
            SqlDataAdapter da = new SqlDataAdapter();
            da.SelectCommand = comm;
            DataSet ds = new DataSet();
            da.Fill(ds, "Name");
            da.Fill(ds, "Employee");
            gvTestUsers.DataSource = ds;
            gvTestUsers.DataBind();
            con.Close();
}

搜索框事件：

protected void Button1_Click(object sender, EventArgs e)
        {
            PopulateGridView();
}

否则每次我尝试使用 EDIT、CREATE 或 DELETE 操作时它都会直接跳转到 Void PopulateGridView。

单击编辑按钮时，如何在不向上滚动的情况下继续编辑一行？

How do I maintain editing a row without scrolling back up when I click on the edit button?
