我有以下代码：

  protected void GridView4_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "UpdateGCommand")
        {
            if (IsPostBack)
            {
                DataSet EditT = new DataSet();
                DataSet ValidT = new DataSet();
                DataRow row;
                if (Session["Edit"] != null)
                {
                    EditT = (DataSet)Session["Edit"];
                }
                if (Session["Valid"] != null)
                {
                    ValidT = (DataSet)Session["Valid"];
                }

                DataTable dtEdit = EditT.Tables[0];
                DataTable dtValid = ValidT.Tables[0];



                GridViewRow gvr = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);
                int RowIndex = gvr.RowIndex;
                row = dtEdit.Rows[RowIndex];
                //------------------------------------------------------------------------------------
                //------------------------------------------------------------------------------------
                //------------------------------------------------------------------------------------
                // Must be able to update the EditT or dtEdit with value from Gridview4 textboxes here
                //------------------------------------------------------------------------------------
                //------------------------------------------------------------------------------------
                //------------------------------------------------------------------------------------
                dtValid.Rows.Add(row.ItemArray);
                dtEdit.Rows[RowIndex].Delete();
                GridView4.DataSource = EditT;
                GridView5.DataSource = ValidT;
                GridView4.DataBind();
                GridView5.DataBind();
            }
            
        }
    }

和以下asp：

            GridLines="None" OnRowCommand="GridView4_RowCommand"

如您所见，由于我不知道要使用什么代码，因此无法从编辑框发送正确的值。请帮忙

使用此代码。可能这就是您所需要的。

 string txtName = ((TextBox) GridView4.Rows[RowIndex].FindControl("textBox1")).Text;
 string txtEmail = ((TextBox) GridView4.Rows[RowIndex].FindControl("textBox2")).Text;
 string txtMobile = ((TextBox) GridView4.Rows[RowIndex].FindControl("textBox3")).Text;

 if (txtName != null) {
   EditT.Tables[0].Rows[RowIndex]["Name"] = txtName;
 }


 if (txtEmail != null) {
   EditT.Tables[0].Rows[RowIndex]["Email"] = txtEmail;
 }

 if (txtMobile != null) {
   EditT.Tables[0].Rows[RowIndex]["Mobile"] = txtMobile;
 }
