This article mainly introduces "how to solve the problem that GridView_RowUpdating cannot get a new value". In daily operation, I believe many people have doubts about how to solve the problem that GridView_RowUpdating cannot get a new value. I have consulted all kinds of information and sorted out simple and easy operation methods. I hope to help you answer the question of "how to solve the problem that GridView_RowUpdating cannot get a new value"! Next, please follow the small series to learn together!

The copy code is as follows:

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)

{

sqlcon = new SqlConnection(strCon);

sqlcon.Open();

string bianhao = Convert.ToString(this.GridView1.DataKeys[e.RowIndex].Value);

string beizhu = ((TextBox)(GridView1.Rows[e.RowIndex].Cells[6].Controls[0])).Text.ToString();

string sqlstr = "SQL statement '";

sqlcom = new SqlCommand(sqlstr, sqlcon);

sqlcom.ExecuteNonQuery();

sqlcon.Close();

GridView1.EditIndex = -1;

bind();

}

The column value is the original one, not the updated one. The reason is that Page_Load loads data, which will be refreshed automatically after each update. Therefore, it is necessary to determine whether the page is returned and loaded again in Page_Load, as follows

The copy code is as follows:

protected void Page_Load(object sender, EventArgs e)

{

if (! Page.IsPostBack)

{

bind();

}

}

At this point, the study of "how to solve the problem that GridView_RowUpdating cannot get a new value" is over, hoping to solve everyone's doubts. Theory and practice can better match to help you learn, go and try it!
